You react 100.0 ml of a 1.01 M HBr(aq) solution with 99.1 mlof a 1.05 M KOH(aq) solution. The density of each solution is 1.04g/ml. The heat capacity of the calorimeter is 7.0 J/C. You observea ΔT of 6.3 C. Assume a 4.18 J/g C specific heat for thesolution.
Calculate the heat evolved in the neutralization.

A 1.00L solution containing 3.50x10^-4M Cu(NO3)2 2.20x10^-3M ethylenediamine(en). The kf for Cu(en)2+ is 1x10^20. What is the concentration of Cu2+(aq) in the solution
If the partial pressures of CO2 and H2O in exhaled air are each 27.0 torr at 30.6°C, calculate the masses of CO2 and of H2O exhaled in 1.00 hour of sleep.
why doen't the mass number decrease? (because there is one less neutron). But the atomic number increases due. What happens to the electrons?
