Question

Balance The equations below:

1. Na + H2O -> NaOH + H2


2. S8 + O2 --> SO3


3. HgO --> Hg + O2


4. Zn + HCl --> ZnCl2 + H2


5. SiCl4 + H2O --> H4SiO4 + HCl

Answer 1

Balanced Equations:-
i) 2Na+2H2O --》2NaOH+H2
ii) S8+12O2--》8SO3
iii) 2HgO --》2Hg + O2
iv) Zn+2HCl--》ZnCl2+ H2
v) SiCl4 + 4H2O --》H4SiO4 + 4HCl

Answer 2

2Na+2H2O --> 2NaOH+H2

S8+12O2 --> 8SO3

2HgO --> 2Hg+O2

2Zn+4HCl --> 2ZnCl2+ 2H2

2SiCl4 + 8H2O --> 2H4SiO4 + 8HCl
