Question

Balance the following Chemical
equation
(i) Zn + O2 → ZnO
(ii) Na + O2 → Na2O
(iii) Fe + Hcl→ Fecl2 + H2​

Answer 1

Step-by-step explanation:

2zn+02 --> 2zno

4Na + O2 --> 2Na2O

Fe + 2HCL --> FeCl2 + H2

Answer 2

(1) Zn+O2 - Zno

Balancing the equation

2Zn + O2 -- 2ZnO

(2) 4Na + O2 -- 2(Na20)

(3) Fe + 2HCl -- FeCl2 + H2
