7. Calculate the energy required to change 1.00 mole of ice at -10.°C to water at 15°C. The heat capacity of ice is 2.03 J/g°C, the heat capacity of water is 4.184 J/g°C, and the molar heat of fusion for ice is 6.02 kJ/mol.
and the molar heat of vaporization for water is 40.6 kJ/mol

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution.part bcalculate the percent ionization of ha in a 0.010 m solution
