Giren equation CaCO3 cao +62 A balanced chemical equation have equal no. of each atom on both side of arrow lets counts the no. of each. atom on left and right side of equation Left side ca=1 right side casi cal c=1 0=3 No.

.
Of each atom es game on both side so it is already a balanced chemical equation. coefficient is the no. of moles as each substance involved in reaction. So tatal no al coefficient of this reaction is 1 (CaCO3) + 1 ccao) + 1 (CO2) = 3 This som af coefficient of this reaction is 3.
