The equations are not balanced. Which equation would have the same coefficients in the same order as 2CO2 3H20 → C2H6O 3O2? Al FeO → Al2O3 Fe CH4 O2 →CO2 H2O PCl5 H2O → HCl H3PO4 FeCl3 NH4OH → Fe(OH)3 NH4Cl.

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
