Front 1

Reactant

Back 1

a substance that takes part in and undergoes change during a reaction.

Front 2

Product

Back 2

an article or substance that is manufactured or refined for sale.

Front 3

Catalyst

Back 3

a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.

Front 4

Inhibitor

Back 4

a thing that inhibits someone or something.a substance that slows down or prevents a particular chemical reaction or other process, or that reduces the activity of a particular reactant, catalyst, or enzyme.

Front 5

Rate of Reaction

Back 5

Reaction rate, the speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.

Front 6

Conservation of Mass

Back 6

a principle stating that mass cannot be created or destroyed.

Front 7

Decomposition Reaction

Back 7

Image result for Decomposition ReactionChemical decomposition, analysis or breakdown is the separation of a chemical compound into elements or simpler compounds. It is sometimes defined as the exact opposite of a chemical synthesis. Chemical decomposition is often an undesired chemical reaction.

Front 8

Synthesis Reaction

Back 8

Image result for synthesis reaction definitionA synthesis reaction or direct combination reaction is a type of chemical reaction in which two or more simple substances combine to form a more complex product. The reactants may be elements or compounds. The product is always a compound.

Front 9

Precipitation Reaction

Back 9

A precipitation reaction refers to the formation of an insoluble salt when two solutions containing soluble salts are combined. The insoluble salt that falls out of solution is known as the precipitate, hence the reaction's name. Precipitation reactions can help determine the presence of various ions in solution.

Single-displacement reaction

Back 10

A single-displacement reaction, also known as a single-replacement reaction, is a type of chemical reaction where an element reacts with a compound and takes the place of another element in that compound. This type of reaction is typically pictured like this: Here, A replaces B in the compound BC.

Front 11

double-displacement reaction

Back 11

A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products

Front 12

chemical reaction

Back 12

a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction.

Front 13

chemical equation

Back 13

A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side.

Front 14

endothermic reaction

Back 14

The term endothermic process describes a process or reaction in which the system absorbs energy from its surroundings; usually, but not always, in the form of heat.

Front 15

exothermic reaction

Back 15

An exothermic reaction is a chemical reaction that releases energy by light or heat. It is the opposite of an endothermic reaction. Expressed in a chemical equation: reactants, products + energy.
