The transfer of energy to the surroundings. 1 of 9 What energy are exothermic reactions usually transferred as and what does this cause? Heat energy causining the surroundings to become hotter. 2 of 9 Name three examples of exothermic reactions? Combustion, oxidation and neutralisation. 3 of 9 Name two everyday uses of exothermic reactions? Hand warmers and self-heating cans. 4 of 9 What is an endothermic reactions do? Take in energy from the surroundings. 5 of 9 What energy are endothermic reactions usually transferred as and what does this cause? Heat energy causing the reaction mixture and it's surroundings to become colder. 6 of 9 Name three example of endothermic reactions? Electrolysis, thermal decomposition and reactions betwwen ethanonic acid and sodium carbonate. 7 of 9 Name an everyday use of endothermic reactions? Sports injury cold packs. 8 of 9 What is reversible reaction? When the reaction in one direction will be exothermic, and the reaction in the other direction will be endothermic. 9 of 9
