You run a reaction which will make ammonia (NH3) as a product. You predict that you should make 6.29 x 1024 molecules of ammonia in your reaction. How many grams of ammonia will you make if your prediction is correct

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
