Answer 1

Answer #1

1.

The number of S atoms is balanced on either side of equation.

There are 2 N atoms on right hand side of equation. So add coefficient 2 to ammonia on reactants side

H and O atoms are balanced on either side of equation. This is the balanced chemical equation

2.

To balance Se atoms, add coefficient 2 to on reactants side

To balance Li atoms, add coefficient 2 to on products side

S and O atoms are balanced on both sides of equation. This is balanced chemical equation

3.

To balance N atoms, add coefficient 2 to on products side

To balance F atoms, add coefficient 3 to on reactants side

This is balanced chemical equation
