what is A and B ?
ltem 5 M Review I Constants I Periodic Table Part A Find the heat of solution for potassium perchlorate when \( 11.0 \mathrm{~g} \) of potassium perchlorate is dissolved with enough water to make \( 107.3 \mathrm{~mL} \) of solution. Express your answer using two significant figures. Part B Determine the temperature change that occurs when \( 11.0 \mathrm{~g} \) of potassium perchlorate is dissolved with enough water to make \( 107.3 \mathrm{~mL} \) of solution. (Assume a heat capacity of \( 4.05 \mathrm{~J} / \mathrm{g} \cdot \) " \( \mathrm{C} \) lor the solution and a density of \( 1.05 \mathrm{~g} / \mathrm{mL} \).) Express your answer usinn two significant figures.
Potassium perchlorate \( \left(\mathrm{KClO}_{4}\right) \) has a lattice energy of \( -599 \) \( \mathrm{kJ} / \mathrm{mol} \) and a heat of hydration of \( -548 \mathrm{~kJ} / \mathrm{mol} \). Find the heat o Express your Part B Determine the te heat capacity of Express your ar
(A) Heat of solution = (Enthalpy of hydration) + (Enthalpy of lattice formation) (Enthalpy of lattice formation) = - Lattice enrgy Thus, Heat of solution (Hsol) of KClO4 = (-548kJ
