Answer 2

$\color{blue}{\huge{\fbox{\bigstar{\mathfrak{\color{red}{..!!Hello\:Mate!!..}}}}}}$

$Mn{0}_{2} + Al ----> {Al}_{2}{O}_{3}+Mn$

let solve this question mathematically

$A Mn{0}_{2} + B Al ----> C {Al}_{2}{O}_{3}+D Mn$

Here is the steps:

A = D

2A= 3C

B = 2C

Let the value of C be 2

so,

B = 2C = 2 (2) = 4

then,

2A = 3C

2A = 3 (2)

2A = 6

A = 6/2=3

then,

A = D

So, D = 3

Therefore,

A=3, B= 4, C=2, D=3

Now substitute this values in place of the letters A,B,C,D.

Surprisingly the equation is balanced.

Here is the balanced equation.

$3Mn{0}_{2} + 4Al ----> 2{Al}_{2}{O}_{3}+3Mn$

This is the easiest method to balance equation..

Hope this is useful..
