Question

write the chemical equations for the following chemical reactions
1. Reaction of zinc with dilute hydrochloric acid
2.reaction of iron with air and water
3.reaction of iron with copper sulphate
4.reaction of hydrogen and oxygen to produce water
5.reaction of an acid and a base

Answer 1

the chemical equations for the following chemical reactions

1) When zinc react with hydrochloride acid.
Zn + 2HCl --- ZnCl2 + H2

2) When iron react with water.
4Fe + 6H2O ---- 2Fe2O3 + 3H2

When iron react with air.
3Fe + 2O2 --- Fe3O4

3) When copper sulphate react with iron.
CuSO4 + Fe ---- FeSO4 + Cu

4) when hydrogen react with oxygen
2H2 + O2 --- 2H2O

5) when acid react with base
HCl + NaOH --- NaCl + H2O
