Balance the following equations:

$Zn plus HNO subscript 3 space rightwards arrow space space space space Zn left parenthesis NO subscript 3 right parenthesis subscript 2 plus NH subscript 4 NO subscript 3 plus straight H subscript 2 straight O$

Solution

Zn plus 2 HNO subscript 3 space rightwards arrow space space space Zn left parenthesis NO subscript 3 right parenthesis subscript 2 plus 2 straight H space space space... left parenthesis 1 right parenthesis

HNO subscript 3 plus 8 straight H space rightwards arrow space space space NH subscript 3 plus 3 straight H subscript 2 straight O space space space space space... left parenthesis 2 right parenthesis space space space space NH subscript 3 plus HNO subscript 3 space rightwards arrow space space space NH subscript 4 NO subscript 3 space space space space space... left parenthesis 3 right parenthesis

Multiplying equation (1) by 4 and adding the three equations.
