Which of the following is the balanced equation for p + o2 → p2o5? question 3 options: a) 4p + o2 → 2p2o b) p + 5o2 → 2p2o5 c) 4p + 5o2 → p2o5 d) 4p + 5o2 → 2p2o5

Given equation:

P + O2 → P2O5

In order for the equation to be balanced, the stoichiometry of the atoms of one kind on the reactant side must be equal to that on the product

Reactants                                            Products

P = 1                                                       P = 2

O = 2                                                     O = 5

The balanced equation would be:

4P + 5O2 → 2P2O5

Reactants                                            Products

P = 4                                                      P = 4

O = 10                                                    O = 10

Ans: D)

Your answer is P + 5O2 → 2P2O5.

This is the answer for K12 Chemistry. I just took the quiz.
