    This presentation will help you to learn how to balance chemical equation easily.

2. Balancing equation
NaOH + H2S -> Na2S + H2O
3. Balancing equation
NaOH + H2S -> Na2S + H2O
You are asked to balance the chemical equation above.
4. Balancing equation
NaOH + H2S -> Na2S + H2O
This equation is too crowded.
5. Balancing equation
NaOH + H2S -> Na2S + H2O
This equation is too crowded.
No space to fill in the coeficient.
6. Balancing equation
NaOH + H2S -> Na2S + H2O
Give space between substances to fill in the coefficient.
