we mix 11 mL of M nitric acid with mL of .695 M calcium hydroxide. Both solutions are initially at 20 degrees celcius. What is the final temperature?

Compare and contrast physical changes with chemical changes.

In a chemical reaction at equilibrium, the rate of the forward reaction the rate of the reverse reaction. if the rate of the forward reaction more products are formed.

3. how much energy in joules is required to evaporate .0005 kg of liquid ammonia to vapor at the same temperature? 4. how much energy ( in megajoules ) is given up by .75 kg of water at 0c when it freezes to form ice at 0c? 5. explain how heat works between and at critical temperatures?
