How many molecules of o2 are required to react with 3.00 moles p4?
p4+5o2⟶2p2o5

molecules of

Explanation:

We have the following balanced equation

According to the stoichiometric coefficients of the reagents for each mole of , 5 moles of are needed,

We apply a simple three rule to find out how many moles of O2 are required for 3 moles of P4 to react

Now we know that we need 15 moles of so that 3 moles of reactions

Remember that 1 mole (of any element or substance) is equal molecules

To find out how many molecules of O2 are required we apply a simple rule of three

To react 3 moles of, molecules of are required

elements make up everything, and they combine to make compounds.

the answer is c
