What is the formula for potassium oxide potassium and oxygen )?
Potassium oxide is an ionic compound formed by combining potassium and oxygen. It carries the chemical formula K2O.
What happens when potassium reacts with oxygen?
Potassium reacts with oxygen to form K2O2 and KO2 only. Xenon, because the first ionization energy is low enough, allowing oxygen to bond to the xenon atom.

What happens when potassium is burned?
Elemental potassium reacts vigorously with water, generating sufficient heat to ignite hydrogen emitted in the reaction, and burning with a lilac-colored flame.
What happens to potassium when heated?
Pure potassium is a highly reactive metal. The conflagration occurs because the combination of potassium and water creates potassium hydroxide (KOH) and hydrogen gas, as well as heat. The heat ignites the hydrogen gas, and the whole shebang goes boom.
What mass of oxygen is formed when 735g of potassium chlorate decomposes?
That is correct. What mass of oxygen is formed when 735g of potassium chlorate decomposes? You should get 288 grams as the answer. You’ve been told you’ve got 735 grams of Potassium Chloride, and so you divide the mass by the molar mass (not twice the molar mass!).
How do you calculate the molar mass of potassium in a reaction?
You are given the mass of Potassium involved in the reaction (7.8) and so divide this by the molar mass of Potassium. This should give: Use m = n x Mr, and so work out the molar mass for K 2 0 and then multiply by the moles already calculated.
How do you calculate the ratio of potassium chloride to oxygen?
You’ve been told you’ve got 735 grams of Potassium Chloride, and so you divide the mass by the molar mass (not twice the molar mass!). And then you have the 2:3 ratio and so work that out. Then you multiply by the mass of O 2 (not three lots of O 2, as you’ve already used the ratio the effectively remove the three!).
What is the mass of oxygen in 192g of magnesium?
What mass of oxygen reacts with 192g of magnesium? 2Mg+O2->2MgO 2 moles of magnesium and 1 mole of oxygen, therefore ratio is 2:1 192/(2×24.3)=3.9moles 3.9×32=124.8g Do I still have to divide 3.9 by 2 because of the ratio?
