PLZ Help! When a sample of 114.97 g NH4NO3 dissolves in 47.07 g of water, the temperature changes from 28.4 C to 7.9 C. Calculate the heat flow (Q) with respect to the water in calories.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

it should be all of them because it asks if you included all of those in your answer

explanation:

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
