Question

Balance the following equation.

Answer 1

Answer:

• 2,1,2

Explanation:

aMg +b O2 --> cMgO

Rule of balancing :- Number of atom of an element should be equal on both side of equation.

Balancing O :- 2b = c

( now by hit and trial method )

for b = 1 => c = 2

and Balancing Mg :-

c= 2 and c = a

=> a = 2

2Mg + O2 ---> 2MgO
