9. Given : P + O2 = P2O5

Balanced Chemical Equation: 4P + 5O2 = 2P2O5

Reactant Product

P = (1) 4 | P = (2) 4

O = (2) 10 | O = (5) 10

Reaction Information

Phosphorus + Dioxygen = Phosphorus Pentoxide

Reaction Type: Synthesis

10. Given: HCl + NaOH = NaCl + H2O

Reactant Product

H = 2 | H = 2
