b) 93.33 litros d) 6 litros

Evaluate this exponential expression,8. (2 + 3)2 – 42

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?

If 22.5 liters of oxygen reacted with excess of hydrogen, how many liters of water vapor could be produced?
