What do subscripts tell you about a compound?

Answer 1

This is farely simple. The subscripts just tell you how many atoms of an element are in the compund. Like this: H20 - Water has 2 hydrogen atoms and 1 oxygen atom CO2 - Carbon Dioxide has 1 carbon atom and 2 oxygen atoms. hence the name carbon di(which means 2)oxide(oxygen). The numbers succeeding elements indicate the number of atoms of that particular

element in the compound. For example, in H20, there are two hydrogen atoms and one oxygen atom. In H2SO4, there ar two Hydrogen atoms, one Sulfur atom and four Oxygen atoms.

Answer 2

The subscript in the equation tells you how many atoms of that element there are in the reaction. For example:

H20 --> H2 + O2

Before the reaction there are 2 hydrogen atoms and 1 oxygen (the subscript 1 isn't shown). After the reaction there are 2 hydrogen atoms and 2 oxygen atoms.

Keep in mind that this is a skeleton equation and isn't balanced yet.

Answer 3

The subscripts following an element tells you the number of atoms of that element in one molecule of the compound. Example: potassium dichromate has the formula K2Cr2O7. There are 2 potassium atoms (K), 2 chromium atoms (Cr) and 7 oxygen atoms (O), in one molecule of the compound.

Answer 4

The subscript in the equation tells you how many atoms of that element there are in the reaction.

Answer 5

the subscript refers to how many atoms of each element are in the molocule. for instance, H2O means two hydrogen molecules and one oxygen molecule.

Answer 6

The subscript to the right of a chemical element symbol tells you how many atoms of that element are present. No subscript means one.
