Please show work for problems 1-4
1. Calculate the activation energy for vacancy formation in aluminum, given that the equilibrium number of vacancies at 500°C (773 K) is 7.57 x10m3. The atomic weight and density (at 500°c) for aluminum are 26.98 g/mol and 2.62 g/cm, respectively 2. What point defects are possible for Al,0, as an impurity in Mgo? How many Al ions must be added to form each of these defects? 3. A sheet of steel 4.5 mm thick...

I. What is the heat capacity of 185g of liquid water? How many Kilojoules are needed to raise the temperature of 10 kg of liquid water from 24.6°C to 46.2°C and 38.5 mol of water from 38.1°C to 79.4°C? Ans: 774.04J/gC, 903.74Kj, 119.75KJ 2. A 2.200 g sample of quinone, C&402. is burned in a bomb Calorimeter whose total heat capacity is 7.854 kJ C. The temperature of calorimeter increases from 23.44°C to 30.57C. What...
