What do subscripts in a chemical equation tell about the equation?
really need help
- the subscripts tell you how many atoms of each kind of element are in the molecule, say you have H2O, this means that there are 2 atoms of hydrogen and one atom of oxygen, likewise, if you have Ca(NO3)2, this means that you have one calcium, two nitrogen, and six oxygen per molecule, the parenthesis tell you that everything inside of them is multiplied by the subscript outside. so N*2 and O3 * 2. you have to understand that the subscript is always referring to the number of atoms of the chemical element that it comes after in the equation, not before.30
