Question

You may never change ----------- in chemical formula

Answer 1

$\bf\huge\underline\red{AnSweR}$

$\implies$You cannot change subscripts in a chemical formula.

•  to balance a chemical equation; you can change only the coefficients.

•  Changing subscripts changes the ratios of atoms in the molecule and the resulting chemical properties.

• For example, water (H2O) and hydrogen peroxide (H2O2) are chemically distinct substances.

Answer 2

Answer:

You cannot change subscripts in a chemical formula to balance a chemical equation;you can change only the coefficient.Changing subscripts changes the ratios of atoms in the molecule and the resulting chemical properties.For example,water (H20) and hydrogen peroxide (H202)are chemically distinct substances.
