Given that the specific heat capacities of ice and steam are 2.06 J/g°C and 2.03 J/g°C, the molar heats of fusion and vaporization for water are 6.02 kJ/mol and 40.6 kJ/mol, respectively, and the specific heat capacity of water is 4.18 J/g°C, calculate the total quantity of heat evolved when 27.2 g of steam at 170°C is condensed, cooled, and frozen to ice at -50.°C.
predict the formula of a compound that presumably would result from the reaction between magnesium and topaline, and name the compound.
how much heat in kj would be required to vaporize 1.00 L of diethyl ether (C4H10O), density is 0.714g/mL at 298 K, if the enthalpy of vaporization at this temperature is 26.0 kj/mol?
