a balloon is filled to a volume of 7.00 times 10^2 mL at a temperature of 20.0 degrees celcius. the balloon is then cooled at constant pressure to a temperature of 1.00 times 10^2 K. what is the final volume of the balloon?
When N2O5 (g) is heated it dissociates into N2O3 (g) and O2(g) according to the following reaction: N2O5(g) N2O3(g) + O2(g) Kc= 7.75 at a given temperature. The N2O3(g) dissociates to give N2O(g) and O2(g) according the following reaction:
