Type of Reactions
This type of reaction involves one compound breaking down into two or more simpler substances.
What is Decomposition?
Increasing this variable (which is a measure of heat) usually speeds up a reaction.
You must have the same number of these on both sides of the equation.
What are atoms?
What are the substances called that start a chemical reaction?
Reactants
What gas is produced when vinegar reacts with baking soda?
Carbon Dioxide
In this reaction, two or more substances combine to form a single compound.
What is synthesis?
These substances speed up a reaction without being consumed.
What are catalysts?
This number goes in front of a compound to balance the equation.
What is a coefficient?
What are the new substances formed in a chemical Reaction?
Products
What kind of reaction causes iron and rust?
Oxidation
A reaction where one element replaces another in a compound.
What is Single Replacement?
The area available for reactants to interact; increasing it can speed up a reaction.
What is surface area?
The law stating matter cannot be created or destroyed.
What is the Law of Conservation of Mass?
What does the arrow in a chemical reaction mean?
Yields or produces
What type of reaction is used in hand warmers?
Exothermic
In this reaction type, two compounds exchange elements or ions to form new compounds
What is double replacement?
A higher concentration of reactants means this will likely happen to the reaction rate.
What is it increases?
Balance _Al + HCl ~ AlCl3 + H2
What forms when two solutions mix and solid appears?
Precipitate
What process converts light energy into chemical energy in plants?
Photosynthesis
This reaction involves oxygen and produces heat and light, often resulting in CO2 and H2O.
What is combustion?
The minimum amount of energy needed to start a reaction.
What is activation energy?
N2 + H2 ~ NH3
N2 + 3H2 ~ 2NH3
In redox reactions, this particle is transferred?
Electron
Fireworks involve rapid reactions that release heat and light. What type of reaction is this?
Combustion
