Answer : The correct option is, 13.7 mole
Solution : Given,
Moles of 
= 27.4 moles
The given balanced chemical reaction is,
From the balanced chemical reaction, we conclude that
As, 2 moles of react with 1 moles of 
So, 27.4 moles of react with 
moles of
Therefore, the number of moles of oxygen required are, 13.7 moles
Answer:
Metal oxides are compounds composed of metal ions and oxide ions. Nonmetal oxides are compounds composed of nonmetal atoms and oxygen atoms. The main difference between metal oxides and non metal oxides is that metal oxides are basic compounds whereas nonmetal oxides are acidic compounds.

Answer:
NH₄Cl, Magnesium sulfate, KCN
Explanation:
Determine whether the given compound name or formula contains a polyatomic ion.
- NH₄Cl. YES. It contains the polyatomic ion ammonium NH₄⁺.
- Magnesium sulfate. YES. It contains the polyatomic ion sulfate SO₄²⁻.
- Sodium phosphide Na₃P. NO.
- Calcium hydroxide Ca(OH)₂. NO.
- KCN. YES. It contains the polyatomic ion cyanide CN⁻.
Answer:
Zero (0)
Explanation:
Since Na^+ has a charge of +1 and Cl^- has a charge of —1 in NaCl
Then the net = +1 —1 = 0
