Chemistry problem, needing help with some equations?

what does the "per" mean when it is in an equation u write. for example: Sodium peroxide or Perbromic Acid. Also the equations for each would help too!

Answer:
Per usually means more than the "usual" amount, typically for the amount of Oxygen in the formula. There are others, though.

For example ,Sodium usually reacts with Oxygen to form Sodium Oxide or Na2O.

But Sodium Peroxide has a formula of Na2O2. If you will notice there is one extra Oxygen or two rather than the usual number of just one.

Bromic Acid has the formula HBrO3 and PerBromic Acid has one more Oxygen with the formula of HBrO4.

Also, in the anion Br03- the charge on Br is +5 but in Br04-, the charge is +7.
Stands for the higher oxidation state.
It usually means more oxygen than the same word without it.
For example, water is H2O. Hydrogen peroxide is H2O2.
Unfortunately, there is no standard as to exactly how many oxygens the letters "per" mean - just that there are more!
