1. What is the difference between an endothermic reaction and an exothermic reaction? 2. There is a 1.80kg of water in a kettle. Calculate the quantity of heat that flows into the water when it is heated from 14.0C to 94.7C. [Specific heat capacity (c), for water is 4.18J/(g.C) ] 3. What would the final temperature be if 300.0J of heat were transferred into 10.0g of methanol initially at 20.0C ? [Specific heat capacity (c), for methanol is 2.918J/(gC) ] 4. Communicate the enthalpy change by using the four methods described in class for the following chemical reaction. Assume standard conditions (SATP) for the measurements of initial and final states. The simple decomposition of aluminum oxide powder (H=+1676kJ/mol aluminum oxide ) 5. In a chemical reaction what does a +H indicate
