Answer the following questions about an endothermic reaction by filling in the blank with the correct term in red provided in brackets. In an endothermic reaction, thermal energy can be thought of as a: (reactant/product) The reaction vessel of a calorimeter becomes (warmer/cooler) A The thermal energy of the reactants-is the products (less/greater) The temperature inside the reaction vessel (increases/decreases) Part D: Calculations A/ A than the thermal energy of
A calorimeter was filled with 50 g of water with an initial temperature of 13 °C then hot water weighing 100 g and a temperature of 97 °C was introduced. The system was allowed to reach equilibrium and the final temperature was 68 °C. What is the specific heat of the calorimeter in J/g °C? Report answer with three significant figures.
