Hydrgen and chlorine are diatomic molecules. They are H2 and Cl2 respectively.
H2 + Cl2 ---> HCl
Reactants --
1. Hydrogen = 2 H atoms (1 H2 molecule)
2. Chlorine = 2 Cl atoms (1 Cl2 molecule)
Product--
1. HCl = 1 H atom and 1 Cl atom
No of atoms in reactants = No of atoms in product
For that, put '2' in front of HCl (product). Read it as 2HCl. Remember '2' is common for both H and Cl. So you will have 2H and 2 Cl respectively in the product side.
H2 + Cl2 ---> HCl (unbalanced/skeleton eqn)
H2 + Cl2 ---> 2HCl (balanced eqn)

(i) Metal hydrgen (bi)carbonate/Metal Carbonate + Acid ---> Metal salt + H2O + CO2
NaHCO3 / Na2CO3 + HCl ---> NaCl + H2O + CO2
KHCO3 / K2CO3 + HCl ---> KCl + H2O + CO2
When metal carbonates/bicarbonates react with an acid, a metal salt, water and carbondioxide are formed.
(ii) Metal + Acid ---> Metal Salt + H2
Zn + HCl ---> ZnCl2 + H2
Mg + HCl ---> MgCl2 + H2
When a metal reacts with an acid, metal salt is formed along with the evolution of hydrogen gas.
