Concept: Balancing Chemical Reactions

Problem: Balance the following equations:(b) P4(s) + O2(g) ⟶ P4O10(s)

FREE Expert Solution

A reaction is balanced when the elements in the reactant side and product side are equal in number of moles.

To balance the given equation:

P4(s) + O2(g) ⟶ P4O10(s)


  •  Count the number of moles of each element in the reactant side and product side.

      In the unbalanced equation, the reactant side has 4 P and 2 O. In the product side, 

      there are 4 P and 10 O.
