Concept: Balancing Chemical Reactions

Problem: Using your newly-found equation balancing knowledge, balance the following equations:1) ___ NaClO3 → ___ NaCl + ___ O22) ___ Ca + ___ O2 → ___ CaO

FREE Expert Solution

We’re being asked to balance the given equations.


Recall that when balancing chemical equations, we have to make sure that the number of elements on both sides is equal with the lowest whole number coefficients.


Reaction 1:

___ NaClO3 → ___ NaCl + ___ O2

Na       1

Na       1

Cl        1

Cl        1

O         3

O         2


Balance O: We have 3 O on the reactant side and 2 O on the product side – add a coefficient of 2 to NaClO3 and a coefficient of 3 to O2:
