In a chemical equation the coefficients
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. WebCHEM 1010 CH 9. Term. 1 / 36.
