Question 1 attached, match each description with the appropriate term.Question 2) Combustion is an example of an exothermic reaction: True or falseQuestion 3) There are modern calorimeters in which the energy released by the combustion reaction is completely transferred to the water with no loss to the surroundings: True or false

v a chemical reaction that occurs in the presence of oxygen and results in the release of energy the amount of heat released when a substance undergoes combustion the energy change for a chemical reaction that involves the formation 1. combustion of a compound from its elements and that is determined 2. exothermic change experimentally under standard conditions 3. first law of thermodynamics a law stating that energy cannot be 4. heat of combustion created or destroyed- energy is always conserved 5. second law of thermodynamics a law stating that when energy is transferred or changed from one 6. standard heat of formation form into another, some of the energy is always transferred to the surroundings (usually as waste heat ) a chemical change that involves a release of energy, usually in the form of heat, to the surroundings
