calculate the amount of heat required to vaporize 8.48g of water at its boiling point
Calculate the change in entropy (in J/K) when a 44.0 g of nitrogen gas is heated at a constant pressure of 1.50 atm from 19.3 ºC to 86.5 ºC.
If a bottle of nail polish remover contains 151 g of acetone, how much heat would be released by its complete combustion?
Calculate the fraction of atoms in a sample of argon gas at 400K that have an energy of 10.0 KJ or greater.
Find the concentration of Cu2+ in equilibrium with CuBr(s)and 0.10 M Br
Calculate the molar mass of the unknown gas. (Remember that the faster the rate of effusion, the shorter the time required for effusion of 1.0 L; that is, rate and time are inversely proportional.)
