Metals react with ______ to form compounds that are alkaline.
2 answers:
Answer: Option (B) is the correct answer.
Explanation:
When metals react oxygen atom then they tend to form metal oxides which are basic in nature. This is because when metal oxides are added in water then it results in the formation of metal hydroxides which are alkaline in nature.
For example,
Whereas when metals react with hydrogen atom then it results in the formation of metal hydrides which are acidic in nature.
When metals react with non-metals then it results in the formation of ionic compounds. These ionic compounds can be acidic or basic in nature.
Not all metals react with metalloids as only a few of them react with metalloids.
Thus, we can conclude that metals react with oxygen (O) to form compounds that are alkaline.

Mass of N₂ will be formed : 50.12 g
<h3>Further explanation</h3>Reaction
2 NH₃(g) + 3 CuO(s) → N₂(g) + 3 Cu(s) + 3 H₂O(g)
moles NH₃ = 3.58
ratio mol NH₃ : mol N₂ = 2 : 1
so mol N₂ :
mass N₂ (MW=28 g/mol) :
