The elements are oxygen and carbon
So C12 is the limiting reactant and P4 is the excess
Mass P4 consumed= 0.31 mol X 123.9 g/mol =38.41 g P4 consumed.
Hope i helped
Two subatomic particles that are located in the nucleus of an atom are Protons and Neutrons.
Ions have an extra or lost an electron. Isotopes have different numbers of neutrons.
1 meter = .001 kilometers so 4.5 x 10^3 = 4500 so .001 x 4500 = 4.5 kilo
