c) sodium oxide is added to water to produce sodium hyodroxied

d)dilute hydrochloric acid react with iron filings

Answer 1

These are the chemical equation to these word equations :

1) 2Al + 6HCl $\to$2AlCl_​3 + 3H₂
2 ) Cu + 2H₂SO₄ $\to$ CuSO₄ + 2H₂O + SO₂
3) Na₂O + H₂O $\to$ 2NaOH
4) Fe + 2HCl $\to$ FeCl₂ + H₂
