Hess's Law describes the conservation of energy in chemical reactions, stating that the heat flow of a reaction is equal to the sum of the heat flow of its composite reactions. A calorimeter measures the heat flow by creating a closed-system that contains the reaction. Ideally, a reading from the calorimeter would show the exact change in heat that a given reaction requires; however, the calorimeter absorbs an amount of heat from the system. Calculating the Qcal, the heat of the calorimeter, allows you to adjust your readings to determine the total heat flow of a reaction.

The seasons are caused as the earth, tilted on its axis, travels in a loop around the sun each year
If this is scientific notation, then the answer is 22290000, or 2.229x10^7
