2) Mg +HCl --> MgCl2 +H2
3) Al + Fe2O3 --> Al2O3 +Fe
4) Na2CO3 + HCl ---> NaCl + H2O+ CO2

Answer 1

Answer:

1)BaCl2 + H2SO4 ----› BaSO4 + 2HCl

2)Mg + 2HCl ---> MgCl2 + H2

3)2Al + Fe2O3 ---> Al2O3 + 2Fe

4)Na2CO3 + 2HCl ---> 2NaCl + H2O + CO2

Explanation:

number of moles on reactant side = no. of moles on product side
