An ice cube is placed in 80 mL of 70oC water. When the ice melts the temperature of the water is 60oC. a. How much energy was needed to melt the ice? Show the steps of how you figured this out b. Use the information on page D-50 to explain how the ice melts. Include information about the energy transfers.

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
