Exothermic gives off energy therefore endothermic keeps energy inside 1 of 10 If we put more energy in than out it's .... And the opposite..... More energy in than out (endothermic) less energy in than out (exothermic ) 2 of 10 What is a reactant and product ? A reactant is what you start with and the product is what you end up with 3 of 10 What is thermal decomposition ? Thermal decomposition is the breakdown of a chemical by heat 4 of 10 Calcium carbonate (heated ) carbon dioxide + calcium oxide Limestone. CO 2. Quicklime 5 of 10 What are properties of materials ? Properties of materials are suited to what it's meant to be used for 6 of 10 What are designer materials ? Designer materials are materials that have been created for a specific purpose 7 of 10 If something fizzes it means .... Gas is being given off 8 of 10 If something whizzes it means ..... Energy is being released 9 of 10 If it bursts into flames .... So much energy has been released it turns to heat and light (flame) 10 of 10
