Question

How do I balance these equations and please show me all the required steps H2 + O2 → H2O ii. HgO → Hg + O2 iii. C + O2 → CO2 iv. Zn + HCl → ZnCl2 + H2 v. Ca + H2O → Ca(OH)2 + H2

Answer 1

Answer:

1. 2H2 + 2O2 => 2H2O ( 4hydrogen atoms on the L.H.S nd R.H.S

similarly.. 4oxygen atoms on the Lhs nd rhs)

2. 2HgO → 2Hg + O2

3. C+ O2 → CO2 ( already balanced )

4. Zn + 2HCl → ZnCl2+ H2

5. Ca + 2H2O → Ca(OH)2 + H2
