4. Determine the final temperature of the solution formed when 0.31 g sodium oxide is added to 100 ml water in a calorimeter. Assume that the volume of the resulting solution is 100 ml. The temperature before reaction is 19°C. The heat capacity of the calorimeter is 20J/°C. Suppose that the specific heat and density of the solution are the same as those of water. Write down all the reaction equations needed to solve this exercise.
