What is a decomposition reaction
A reaction that splits one reactant into two
100
What is a exothermic reaction
A reaction that releases energy into its surroundings (usually in the form of heat)
100
What are the two parts of a chemical equation?
The reactants and the Products
100
What happens when you balance an equation?
You add coefficients to molecules on each side of the problem to help make the number of each atom on both sides the same.
200
What is a synonym of a synthesis reaction
An addition reaction
200
What is an endothermic reaction
A reaction that needs to absorb heat from its surroundings to proceed in the reaction
200
Do the reactants turn into products, or are the reactants created by the products?
They turn in to the products
