Balancing equation
This presentation will help you to learn how to balance
chemical equation easily.
Balancing equation
NaOH + H2S → Na2S + H2O
You are asked to balance the chemical equation above.
Balancing equation
NaOH + H2S → Na2S + H2O
We’ll do it in 3 easy step :1. Mark the elements with
color2. Connect coefficients with
the same color3. Adjust the coefficients.
Balancing equation
NaOH + H2S → Na2S + H2O
No space to fill in the
coefficient.
Balancing equation
NaOH + H2S → Na2S + H2O
NaOH + H2S → Na2S + H2O
Give space between substances to fill in the
coefficient.
Balancing equation
NaOH + H2S → Na2S + H2O
Put in boxes to fill up coefficients.
