How to balance these chemical equations: - 1.NaOH+H2SO4-Na2SO4+H2O
- 2.KClO3-KCl +O2
- 3.Hg(NO3)2+KI - HgI2+KNO3
The balanced chemical equation is as follows:
1. 2 NaOH (aq) + H2SO4(aq) Na2SO4(aq) + 2 H2O(l)
2. 2 KClO3(s) 2 KCl(s) + 3 O2(g)
3. Hg(NO3)2 (aq) + 2 KI (aq) HgI2(aq) + 2 KNO3
1. 2 NaOH (aq) + H2SO4(aq) Na2SO4(aq) + 2 H2O(l)
2. 2 KClO3(s) 2 KCl(s) + 3 O2(g)
3. Hg(NO3)2 (aq) + 2 KI (aq) HgI2(aq) + 2 KNO3
