You are running a calorimetry experiment where you are trying to determine the number of Calories (with a capital C!) in a peanut. You set up your aluminum can of water and take all your initial data, putting it in the table below. Then, you set your peanut ON FIRE You finish filling out your table once the peanut has gone out. How many Calories of heat did your peanut release? Round your answer to two digits after the decimal point.
Initial Mass of Peanut
3.11 grams
Final Mass of Peanut
0.52 grams
Mass of Water
60.7 grams
Initial Temp of Water
22.4 degrees C
Final Temp of Water
75.6 degrees C

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

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?
