Question

plese do this balence

Answer 1

mg+o2=mgo
=2mg + o2=2mgo

Answer 2

heya

here is ur answer

======================

given skeleton equation :-


Mg + O2 ====> MgO

step -1 :- Mg + O 2 ==> MgO

step -2

number of atoms in LHS and RHS

LHS-Mg - 1

RHS - Mg -1

LHS - O - 2

rhs- O -1

↪ so oxygen is not Balanced

↪ multiplying with 2 on RHS

step -3 :-

Mg + O 2 ===> 2MgO

step -4 :-

number of atoms in LHS and RHS

LHS - Mg - 1

RHS - Mg - 2

LHS - O - 2

RHS - O -2

↪ Mg in LHS is not Balanced ,so let's multiply by 2

step - 5

2Mg + O2 ===> 2MgO

step -6

number of atoms in LHS and RHS

LHS - Mg-2

RHS -Mg -2

LHS - O -2

RHS - O -2

step - 7

2Mg + O2 ====> 2MgO ↪ Balanced equation.

hope it helps u..!!
