Question

In balancing a chemical equation, which of the following are you allowed to do?

A) change coeffecients
B) change superscripts
C) change subscripts
D) add new substances

Answer 1

When you balance an equation you can only change the coefficients(the numbers in front of molecules of atoms). Coefficients are the numbers in front of the molecule. Subscripts are the smaller numbers found after atoms. These cannot be changed when balancing chemical equations

Answer 2

Change Coefficients
