What are products?
Substance that forms in a chemical reaction.
What are reactants?
Participates in chemical reaction and can be a substance or a molecule.
What is chemical energy?
Energy that is released in a chemical compound and r ads to produce new compounds.
What is exothermic reaction?
Chemical reaction that is when heat is released to the surroundings.
What is a endothermic reaction?
Requires heat to have a chemical reaction
What is a synthesis reaction?
Reaction which 2 or more substances combine to make a new compound.
What are decomposition reactions?
Reaction that has to have a single compound that breaks down to form 2 or more simpler substances.
What is a electrolysis?
Process that a electric current is used in to produce a chemical reaction such as decomposition of water.
What is a combustion reaction?
A oxidation reaction of organic compounds that releases heat.
What is a single displacement reaction?
One element or radical takes place of another element or radical in a compound.
Double displacement reaction
Reaction that gas, a solid participate, or a molecular compound forms from the apparent exchange of atoms or ions between new compounds.
Oxidation reduction reaction
Any chemical change that one species is oxidized and another species is reduced.
What are radicals?
Organic group that has one or more electrons available for bonding.
Chemical equation
Representation of chemical reactions that have symbols to show their relationship between reactants and products.
What are mole ratios?
Relative number of molds of substances that is required to produce a given amount of product in a chemical reaction.
What are catalysts?
Substances that changes the rate of chemical reactions without being consumed or changed significantly
What are enzymes?
Type of protein that speeds up metallic reactions in plants and animals with out being changed or destroyed permanently.
What is a substrate?
Part, substance, or element that lies beneath and supports another part, substance, or element that the reactant in reactions catalyzed by enzymes.
Chemical equilibrium
State of balance that rate of a forward reaction equals the rate of reverse reaction and concentrates of products and reactants remain unchanged.
What is reduced
Substance that accepts electrons
Oxidized
Substance that gives up electrons
Coefficient
Equation balanced only by putting number in front
Law of conservation mass
mass is neither created nor destroyed in chemical reactions.
Law of definite proportion
a chemical compound always contains exactly the same proportion of elements by mass.
