Denali has a spectacular aura about
Chemistry question?

Determine the amount of heat (in joules) absorbed or released in each of the following changes.

5. 100.0 g of ice melted, with no temperature change
6. 40.0 g of water, boiled at 100.0 degrees C
12. 47.8 g of lead melted, with no change in temperature
14. The complete vaporization of 53.8 g of lead at its boiling point.

You don't have to do all of them. Pick one and show me how to do it. I will choose best answer based on how many you do and if you explain it well. Thanks!
