What is 1 copper, 1 sulfur, 2 hydrogens, and 5 oxygens?


Energy is stored here in a chemical compound


What are chemical bonds?


Reactions, such as burning, that release energy


What are exothermic reactions?


Energy required to start a reaction


What is Activation energy?


Type of reaction in which the products contain more energy than the reactants


What is an endothermic reaction?


Type of energy reaction shown by this graph:


What is an exothermic reaction?


Solid that forms from a solution in a chemical reaction


What is a precipitate?


Two or more elements chemically combined in a specific ratio


What is a compound?


H2, H2O, and H2SO4 are examples of these


What are molecules?


Indicates how many atoms of each element are present in a molecule

Water stops fires by keeping fuel from coming into contact with this


What is oxygen?


Iron rusting is this type of change


What is a chemical change?


Making lemonade is this type of change


What is a physical change?


Used to slow down a chemical reaction


What is an inhibitor?


Adding heat has this effect on a reaction


What is SPEED UP the reaction?


The effect that decreasing surface area has on the rate of a reaction


What is SLOW or DECREASE the rate of the reaction?
