10 Potassium Facts (K or Atomic Number 19)

10 Potassium Facts (K or Atomic Number 19) Potassium is a light metallic element that forms many important compounds and is essential for human nutrition. Here are 10 fun and interesting potassium facts. You can get more details about potassium on the potassium facts page. Fast Facts: Potassium Element Name: PotassiumElement Symbol: KAtomic Number: 19Atomic Weight: 39.0983Classification: Alkali MetalAppearance: Potassium is a solid, silvery-gray metal at room temperature.Electron Configuration:  [Ar] 4s1 Potassium is element number 19. This means the atomic number of potassium is 19 and each potassium atom has 19 protons.Potassium is one of the alkali metals, which means it is a highly reactive metal with a valence of 1.Because of its high reactivity, potassium is not found free in nature. It is formed by supernovas via the R-process and occurs on Earth dissolved in seawater and in ionic salts.Pure potassium is a lightweight silvery metal that is soft enough to cut with a knife.  Although the metal appears silver when its fresh, it tarnishes so quickly that it normally appears dull gray.Pure potassium usually is stored under oil or kerosene because it oxidizes so readily in air and reacts in water to evolve hydrogen, which may be ignited from the heat of the reaction.The potassium ion is important for all living cells. Animals use sodium ions and potassium ions to generate electric potentials. This is vital for many cellular processes and is the basis for the conduction of nerve im pulses and stabilization of blood pressure. When not enough potassium is available in the body, a potentially fatal condition called hypokalemia can occur. Symptoms of hypokalemia include muscle cramps and irregular heartbeat. An overabundance of potassium causes hypercalemia, which produces similar symptoms.  Plants require potassium for many processes, so this element is a nutrient that is readily depleted by crops and must be replenished by fertilizers. Potassium was first purified in 1807 by Cornish chemist Humphry Davy (1778–1829) from caustic potash (KOH) via electrolysis. Potassium was the first metal to be isolated using electrolysis.Potassium compounds emit a lilac or violet flame color when burned.  It burns in water, just like sodium. The difference is that sodium burns with a yellow flame and is more likely to shatter and explode!  When potassium burns in water, the reaction releases hydrogen gas. The heat of the reaction can ignite the hydrogen.Potassium is used as a heat transfer medium. Its salts are used as a fertilizer, oxidizer, colorant, to form strong bases, as a salt substitute, and for many other applications.  Potassium cobalt nitrite is a yellow pigment known as Cobalt Yellow or Aureolin.The name for potassium comes from the English word for potash. The symbol for potassium is K, which is derived from the Latin kalium and Arabic qali for alkali. Potash and alkali are two of the potassium compounds k nown to man since ancient times. More Potassium Facts Potassium is the 7th most abundant element in the Earths crust, accounting for about 2.5% of its mass.Element number 19 is the 8th most abundant element in the human body, accounting for between 0.20% and 0.35% of body mass.Potassium is the second lightest (least dense) metal after lithium.Three isotopes of potassium occur naturally on Earth, although at least 29 isotopes have been identified. The most abundant isotope is K-39, which accounts for 93.3% of the element.The atomic weight of potassium is 39.0983.Potassium metal has a density of 0.89 grams per cubic centimeter.The melting point of potassium is  63.4  oC or  336.5 K and its boiling point is  765.6  oC or  1038.7 K. This means potassium is a solid at room temperature.Humans can taste potassium in aqueous solution. Dilute potassium solutions taste. Increasing the concentration leads to a bitter or alkaline flavor. Concentrated solutions taste salty.One lesser-known use of potassium is as a portable oxygen source. Potassium superoxide (KO2), is an orange solid used to release oxygen and absorb carbon dioxide in respiration system for submarines, spacecraft, and mines. Sources Haynes, William M., ed. (2011).

Is College Worth It Professor Ramos Blog

Is College Worth It Is college worth it? College is a business and like all businesses it’s a large investment. An investment in time, money and sometimes even your social life. Many choose college because of the benefits it promises those considering a way out of fast food and other entry-level jobs. But, is college for everyone? Is college for you? This is something I myself struggled with and questioned when I was going through the enrollment process when trying to determine what it was I wanted out of college. In this article I’ll break down some numbers and give you some key examples as to why college isn’t for everyone and why college isn’t needed to be successful. The enrollment rate of college students from the years 2000 to 2018 have sky rocketed from 15.3 million students to 19.9 million. A staggering 4.7 million student difference in only 18 years and it doesn’t stop there, by 2027 its projected that the enrollment rate will increase to 20.5 million students! A number produced by the National Center for Educational Statistics (https://nces.ed.gov/fastfacts/display.asp?id=372). So why is it that more people are going to college? â€Å"From an early age, we get the message that going to college is as crucial step in life† (315), we see this advertised on billboards, the sides of building, in commercials, our communities, online advertisements and pressure from our friends and family. College propaganda has become burnt into American culture (thanks Obama), But interesting enough the drop out rates are actually decreasing, a survey analyzing the drop out rates from the years 2000 to 2016 went from an average drop out rate of 10. 9 percent to a surprising 6.1 percent. (https://nces.ed.gov/fastfacts/display.asp?id=16) So, Is this a good thing? While these numbers are impressive, they’re a little misleading. For most students unable to afford college; the ones working their 9-5 jobs, raising kids, living on their own, etc., The question of whether or not college is worth it no longer remains the issue but rather, is the cost worth it? The average middle class American typically can’t afford colleges increasing tuition rates. These students are usually forced to apply for grants and loans to make it through college with the hopes of landing in a good university, and ultimately get their dream job (which is the goal). But if these goals aren’t financially and articulately planned out ahead of time, the â€Å"helping hand† financial aids offer come with a major â€Å"backhand† of debt. â€Å"The average student debt in the united states is $32,731, while the median student loan debt amount is $17,000† (https://www.valuepenguin.com/average-student-loan-debt) This means that the average students graduating with debt may have been better off never going to college in the first place, but sadly most well-paying careers require a college degree and prior experience. A contradiction that leaves college graduates over-educated and underpaid with degrees they can’t use for jobs that won’t hire them. ï ¿ ¼ (image source: https://www.insidesources.com/college-debt-vs-education-choices/) So while student drop out rates are decreasing, the average student debt is catapulting, leaving its mark on the American economy. A hindsight that is happening right before our eyes and I’m sure someone right now reading this article is feeling the full effect of their empty wallet because of college. It’s no joke, but you may be thinking to yourself, â€Å"What about grants? What about scholarships?â€Å" Yes, grants are an option that help out tremendously with the cost of college but rarely do they cover the full cost of tuition rates and while scholarships are a huge financial weight off the shoulder, applying yourself and acquiring the right ones is a skill in itself, a skill set very few know. Weighing the pros and cons of college takes a bit of consideration as to whether or not its right for you. The pros of having a college degree means more options and better paying careers, the average college graduate making $570,000 more than just high school graduate ov er a life time (that’s about a 71%-136% more in pay than the average high school diploma holder). But the dark side of this graduates paradise is the debt that comes hand in hand. It was reported as of May 2018, roughly 44 million American college graduates owed over $1.5 trillion in student debt and 45% of these people surveyed said college wasn’t worth it. (https://college-education.procon.org/). Bradley Gauthier, a college graduate, managed to rack up $68,472 in student debt, he writes about how college ruined his life and the mistakes he made to acquire this debt. At an early age he built a thriving business that implemented technology in residences and offices, but later he liquidated the business to attend and help him pay for his time in college. This quickly took a turn for the worse when it wasn’t enough and Gauthier began to pull out loans to help him the rest of the way through. â€Å"But it’s too late, I’ve accrued a mortgage payment equivalent monthly loan amount. Before consolidation I’m looking at $750 a month just to pay interest. I’ve been out of college 4 years and I still have yet to begin paying down the principal.† A direct quote from Bradley Gauthier’s article How College Ruined My Life (http://blog.bradleygauthier.com/how-college-ruined-my-life/) With that kind of debt and the interest rates that come with it, it is likely he’ll never be able to fully pay off this debt in his life time without some help. In my own personal opinion, if one is to choose the high road and pursue a better education, you’ll need to first find what it is you want out of college. Having a major is a start, but that doesn’t mean you need to stay permanent to the major you chose and unintentionally land a career you may eventually hate. It’s also not a good idea to pick a handful of random classes just because you want them, wasting not only your money but the governments as well. The point I’m trying to make is if your unsure of what it is you want out of college but you want the education (plus the career options) you’ll need to sit down and decide if it’s worth it for you. Many succeed in life debt free without college. Some being college drop-outs themselves acquiring better pay than even college graduates. Bill Gates being one the most influential examples of this; On his way to becoming a lawyer just like his father, Gates gets inspired by a magazine clip about Altair computers, calls the Altair computer company about a computer language he (hadnt yet) wrote and boom, a snow ball of hardwork took hold of his life tranforming him into the billionaire we know today. Another great example that hits a soft spot in my own personal life is my oldest brother, Dylan Werner. He was a college student and acquired a degree to become a Firefighter/Paramedic, but he soon realized it wasn’t for him. He left his career job entirely and became an entrepreneur. Ill spare you all the minor details inbetween, but Dylan now is a millionaire, traveling the world teaching yoga and fulfilling his dreams (true story, go check him out https://www.dylanwerneryoga.com/ ). ï ¿ ¼(Photo of Dylan Werner; via Instagram @dylanwerneryoga) The point of the matter is that he built a career for himself without the help of a piece of paper telling him he was fit for the job. College is a major commitment, it can be taxing on all aspects of life, but it can also be fun if you make the right choices and HAVE A PLAN! If you want to be a doctor and you think that will make you happy then go and get that degree! Just know College isn’t for everyone so going off the notion that in order to succeed in life you need a college degree simply isn’t true. Read against the grain, learn from everything, find what it is that makes you happy and stick with it. Sometimes the most unexpected things turn into success, and if college is the thing that makes you happy, then keep making college work for you. But if it isnt, then go and make your own path.

Without a Paddle Amazon and Hachette and Us

Without a Paddle Amazon and Hachette and Us Without a Paddle: Amazon and Hachette and Us Hi. At Reedsy we live, sleep, and all but photosynthesise self-publishing news and discussion. Even if you were living under a rock, a massive rock, like a boulder, you wouldn’t have been able to avoid the suddenly very loudly proclaimed views of authors both traditionally published and self-published over the whole Amazon-Hachette blood war that’s been happening for over a month now. So we had to say something. In fact, we said two things. Below you can find Dave’s take, and you can find Ricardo’s perspective over here.–Well, that was a hell of a week.The Amazon/Hachette cold war is now into its second month. Hachette’s books continue to suffer difficulties on Amazon’s store, including availability issues and price increases.On Wednesday Douglas Preston released an open letter to readers. Previously it had been quietly circulating amongst authors, collecting signatures including Robert A. Caro and Stephen King. Preston et al asked Amazon to â€Å"resolve its dispute with Hachette without hurting authors and without blocking or otherwise delaying the sale of books to its customers.†Self-published author Hugh Howey responded almost immediately on change.org petitioning Hachette to â€Å"stop fighting low prices and fair wages It’s almost absurdly comic, by the way, that this whole conversation has continued without a real, firm context of what exactly Amazon are asking for. The issue driving this could be anything from Amazon demanding discounts and charging for pre-order buttons to Jeff Bezos personally demanding Hachette deliver a plump firstborn male infant every Summer Solstice in unholy tribute.

Critical review of journal of counselling psychology qualitative Essay

Critical review of journal of counselling psychology qualitative research - Essay Example Both therapies are illustrated in detail through corresponding case studies. The purpose of the abstract is to draw the readers’ attention to the issues that the paper deals with such as the eating disorders Anorexia Nervosa and Bulimia Nervosa and to focus their attention accordingly on the details of the main topic of the paper which are the evidence-based treatments for children and adolescents afflicted with these eating disorders. The article was crafted very well that it was able to achieve its goal of informing the readers thoroughly about the eating disorders of Anorexia Nervosa and Bulimia Nervosa as well as the available psychological interventions effective for treatment and management of the disorders. 2. What are the main areas of information contained in the Introduction? In the introduction, eating disorders were discussed, specifically, the onset of Anorexia Nervosa (AN) and Bulimia Nervosa (BN) in children and adolescents. ... It was not reported what factors may be responsible for it and if family-based interventions were suggested, it was not clear why.
