WebDec 2, 2024 · Coefficients are whole number multipliers. If, for example, you write 2 H 2 O, that means you have 2 times the number of atoms in each water molecule, which would be 4 hydrogen atoms and 2 oxygen atoms. As with subscripts, you don't write the coefficient of "1", so if you don't see a coefficient, it means there is one molecule. WebMar 7, 2024 · C3H 8 + O2 → 3CO2 +4H 2O The last step is to determine the coefficient of the oxygen gas on the LHS. We see that we have 6 +4 = 10 oxygen molecules on the RHS, so we will have 10 2 = 5 molecules on the LHS. The final balanced chemical equation is C3H 8 + 5O2 → 3CO2 + 4H 2O iron skillet wisconsin
