Question by pubertycrap: How do I write the equation of a chemical reaction when potassium and oxygen combine to form potassium oxide?
As I write the equation of a chemical reaction when potassium and oxygen combine to form potassium oxide? I thought it was K + O2 ——–> KO2 be sought but I found the formula, instead of K2O. Which one is right? And if it please the K2O erklären.Vielen Thanks to all!
Best answer:
Answer by Alan F The valency of potassium is 1, having 1 electron in outer shell.
The valency of oxygen is 2 having 2 electrons in it’s outer shell.
So the product is K2O
Your reaction would indicate a velency of 1 or 2 for potassium depending on valency you give oxygen
04/04/10 Update: The chemical name for Epsom salt is “magnesium sulfate”. Magnesium is extremely viable in flame even in smail quantities are emergency lighters developed bars of magnesium to be shaved in small batches of magnesium power, then a spark from a flint and magnesium increases instantly prepared …. sounds deadly. Gritweed cotaminated is marijuana. This game sparkles gritweed, when ignited, and was well immersed in the epson salt solution during the drying process. Gritweed can pollute any of the folowing: Ground glass, sand, quartz, sugar, Epsom salt, baking soda. Some are gritweed with spray on glass etching. This is done to add weight to buds. Gritweed hit the UK in ’07 and ’08. There is very little evidence of U.S. gritweed … up to now. Be aware and spread the word about this dangerous situation. Let Buy to sell it, dont, do not smoke it!

We show you how to protect rust galvanized metal objects. First, we get 30 g of zinc sulfate and dissolved in 100 ml of water. Zinc sulfate was back in our video about the creation of a copper sulfate and zinc battery: www.youtube.com Then connect the element that allows you to mobilize to the negative terminal of a 5-volt power supply. Connect the positive terminal on a strip of metallic zinc. Zinc metal was from our video on getting materials from batteries get: www.youtube.com Immerse both electrodes into the zinc sulphate solution and keep it touch. Then on the current train and run it for about a minute to give the metal a zinc coating. Remove the object and now it is galvanized. To test the rust, put it on a paper towel soaked in salt water. You should also place a dot beside it unprotected for a good comparison. Cover the towel to prevent evaporation and then wait a day or two. The treated object should remain rust-free, perhaps the development of a white crusty coating. The untreated object should attaches rust. Video Rating: 4 / 5
Any of three classes of chemical compounds containing the element sulfur. The three classes of sulfides include inorganic sulfides, organic sulfides (sometimes called thioethers), and phosphine sulfides. Inorganic sulfides are ionic compounds containing the negatively charged sulfide ion, S2−; these compounds may be regarded as salts of the very weak acid hydrogen sulfide. Organic sulfides [...]more →
