Question

Balance the following chemical equations.


a) HNO 3 + Ca(OH) 2 - Ca(NO) 2 + H2O


b) NaOH + H2 SO 4 - Na 2 SO4 + H2O


c) Nacl + AgNO 3 - AgCl + NaNO3


d) Bacl2 + H2 SO4 - BaSO4 + HCl​

Answer 1

a) 2HNO 3 + Ca(OH) 2 - Ca(NO3) 2 +2 H2O

b)2NaOH + H2 SO 4 - Na 2 SO4 + 2H2O

c) already balanced

d) Bacl2 + H2 SO4 - BaSO4 + 2HCl

Explanation:

count no.of atoms of different elements on each side and manage the equation in such a way that both side atoms are equal

Answer 2

(a) 2HNO 3+Ca(OH) 2→Ca(NO 3 ) 2 +2H 2 O

(b) 2NaOH+H 2 SO 4 →Na 2 SO 4+2H 2 O

(c) NaCl+AgNO 3 →AgCl+NaNO 3

(d) BaCl 2 +H 2 SO 4 →BaSO 4+2HCl
