2 is the answer iam not sure about it
Yes
<u>Answer:</u> 6 moles of 
will be decomposed.
<u>Explanation:</u>
We are given:
Moles of oxygen gas produced = 9 moles
The chemical equation for the decomposition of follows:
By the stoichiometry of the reaction:
If 3 moles of oxygen gas is produced by 2 moles of
So, 9 moles of oxygen gas will be produced by = 
of
Hence, 6 moles of will be decomposed.
Answer:Heterogeneous
Explanation:they can be separated by using the method of winnowing
Molar mass:
NH₃ = 14 + 1 * 3 = 17.0 g/mol
hope this helps!
Answer:
Acid + Base -------> Salt + Water
Explanation:
The reaction between an acid and bases is called a neutralization reaction. The result of the reaction is salt and water. For example, when hydrochloric acid(acid) and sodium hydroxide(base) react they form sodium chloride(salt) and water. Also, heat is evolved.
Example:
HCl + NaOH ----------> NaCl + H2O
HCl is hydrochloric acid.
NaOH is sodium hydroxide which is a base.
NaCl is sodium chloride which is a salt.
H2O is water.
