What is diatomic?
This type of reaction occurs when an element displaces another element in a compound, producing a new compound and a new element.
What is a single replacement reaction?
How does the concentration of reactants affect the reaction rate?
More reactants mean a faster reaction.
water → hydrogen + oxygen

A chemical equation
Increasing the temperature of a solution will ________________________ the speed of the substance dissolving.
What is increase?
A hydrocarbon will combine with oxygen and in the process, give off energy in the form of light and heat to produce carbon dioxide and water.
What is combustion?
