Question

In the chemical question CH4 + 2O2 CO + 2H2O, What is the total amount of mass that is represented by the reactants methane (CH4) and oxygen (O2), in amu?

Answer 1

Answer:

CH4 + 2 O2 → CO2 + 2 H2O + energy The energies of the products are lower than the energiies of the reactants.

Answer 2

Answer:

Mass of carbon is 12

Mass of hydrogen is 1

Mass of methane is 12+4×1

12+4=16
