Question

Q4) Balance the following equations
i) H2 + O2 - H20
ii) N2 + H2= NH3
iii) C + 02 = Co2
iv) Ca + Hal =CaCl2 + H2
v) Na + O2 = Na20​

Answer 1

Answer:

i) 2H₂+O₂=2H₂0

ii)N₂+3H₂=2NH₃

iii)C+O₂=CO₂

iv)Ca+2HCl=CaCl₂+H₂

v)4Na+O₂=2Na₂O

Answer 2

(i) 2H2 + O2 → 2H2O

(ii) N2 + 3H2 → 2NH3

(iii) 2C + O2 → 2CO2

(iv) Ca + 2HCl → CaCl2 + H2

(v) 4Na + O2 → 2Na2O
