Answer 1

Explanation:

a) Mg + Hcl = MgCl2 + H2

= Mg + 2HCl → MgCl2 + H2

b)NaOH + H2SO4 =Na2SO4 + H2O

=2 NaOH (aq) + H2SO4 (aq) → 2 H2O (l) + Na2SO4 (aq)

c)Ca(OH)2 + Cl2 = CaOCl2 + H2O

=Cl2 + Ca(OH)2 → H2O + CaCl2 + Ca(ClO3)2

d)Pb(NO3)2 = PbO + NO2 + O2

= 2Pb(NO3)2 → 2PBO + 4NO2 + O2.

e)Ca(HCO3)2 +Na2CO3 = CaCO3 +NaHCO3

= Ca(HCO3)2 (aq) + Na2CO3 (aq) → 2 NaHCO3 (aq) + CaCO3 (s)

Hope this will help you.
