In an exothermic reaction heat is given out to its surroundings 1 of 9 What is the best example of an exothermic reaction? Burning Fuels 2 of 9 What happens to heat in an endothermic reaction? In an Endothermic reaction heat is taken in from the surroundings. 3 of 9 What is the best example of an endothermic reaction? Thermal decomposition 4 of 9 What kind of reaction is adding an acid to an alkali and why? Adding an acid to an alkali is an Exothermic reaction because you will see an increase in temperature. 5 of 9 What kind of reaction is dissolving aluminium nitrate in water and why? Dissolving ammonium nitrate in water is an Endothermic reaction because it results in a drop in temperature. 6 of 9 What kind of reaction is bond breaking and why? Bond breaking is an endothermic reaction because energy must be supplied to break bonds. 7 of 9 What kind of reaction is bond making and why? Bond making is an Exothermic reaction because energy is released when new bonds are formed. 8 of 9 What does the calorimetric method involve? Measuring the change of heat in a chemical reaction. 9 of 9
