Answer:
Explanation:
Matter can be classified into two broad categories: pure substances and mixtures. ... A substance that can be broken down into chemically simpler components (because it has more than one element) is a compound. For example, water is a compound composed of the elements hydrogen and oxygen.
Answer:
80.043 g/mol
Explanation:
Ammonium nitrate is a chemical compound, the nitrate salt of the ammonium cation. It has the chemical formula NH ₄NO ₃, simplified to N₂H₄O₃. It is a white crystalline solid and is highly soluble in water. It is predominantly used in agriculture as a high-nitrogen fertilizer.
Answer:
3.2 g of O₂
Solution:
This reaction is for the formation of Potassium Superoxide, The reaction is as follow,
K + O₂ → KO₂
First let us confirm that either the given amount of Potassium produces the given amount of Potassium oxide or not,
So,
As,
39.098 g (1 mole) K produced = 71.098 g of K₂O
So,
3.91 g of K will produce = X g of K₂O
Solving for X,
X = (3.91 g × 71.098 g) ÷ 39.098
X = 7.11 g of K₂O
Hence, it is confirmed that we have selected the right equation,
So,
As,
39.098 g of K required = 32 g of O₂
So,
3.91 g of K will require = X g of O₂
Solving for X,
X = (3.91 g × 32 g) ÷ 39.098 g
X = 3.2 g of O₂
Answer:
Faster, and the substance will be a gas.
Explanation:
I'm quite not sure with it. But, I've tried my best. Since maybe the substance is liquid
