A 22.0 g sample of propane is burned in a bomb calorimeter that contains 300. g of water. If the temperature change is 18.5∘C and the heat capacity of the calorimeter is 824 J∘ C, how much heat was released by the combustion of the propane sample? Assume the heat capacities of the reaction products are negligible compared to that of the water and the calorimeter.

Astudent is trying to create a table that compares hypotheses, theories, and laws. hypothesis theory law do scientific researchers formulate it? yes yes yes does it explain why things happen? yes yes no yes yes yes is it used to make predictions? no yes yes which of the following questions would most likely fill the blank in the table? is it an intelligent guess? is it newly formulated? is it based on observations? has it been proved?
