Good evening
how formulas are made​

Answer 1

Answer:

A chemical formula identifies each constituent element by its chemical symbol, and indicates the proportionate number of atoms of each element. In empirical formulas, these proportions begin with a key element and then assign numbers of atoms of the other elements in the compound—as ratios to the key element.

Answer 2
