Balancing Chemical Equations Introduction
Part 1 Directions:
1) Put a circle around the product(s), 2) Put a square around the reactant(s), 3) Underline the subscripts, 4)
Balance the chemical equations. Make sure there is the same number on both sides of the equation.
A.
S8 +
O2
SO2
B.
K10 +
Na3
K + Na6
C.
N2 +
Ca2
N2Ca
D.
Al +
C2
Al2C3
Part 2 Directions:
Check each of the chemical equations and identify if the equation is balanced or not balanced. Then circle the color
in the correct column and then add that color to all of the matching numbers on the picture on the back.
