1. No, the are not the same.
The Combined Gas Law is:
P1V1/T1 = P2V2/T2
The Ideal Gas Law is:
PV = nRT
Your chemistry textbook should explain the difference. The most importance difference is that in the Combined Gas Law, the amount (moles) of gas are assumed to be constant. In the Ideal Gas Law, the amount of gas is one of the variables.
