Chemical Reactions Will

Substance that forms in a chemical reaction.

A substance in a chemical reaction.

Energy released when a chemical compounds reacts to make new compounds.

Reactions that release energy. Ex isooctane-oxygen reaction, more energy is released as the products form than is absorbed to break bones in the reactants.

Reaction that absorbs energy. If you put hydrated barium hydroxide and ammonium nitrate together in a flask, the reaction between them takes so much energy from the surroundings that water in the air will condense and then freeze on the surface of the flask.

When small molecules join together in chains to make larger structures called polymers.

When substances are broken apart.

The simplest decomposition reaction.

Reaction where oxygen is a reactant.

Atoms of one element appear to move into a compound and atoms of the other element appear to move out.

When two compounds appear to exchange ions.

Electron transfer.

When electrons are available for bonding.

Chemical change in which electrons are gained by removal of oxygen.

When reactant loses one or more electrons.

Representation of a chemical reaction.

Relative number of moles of a substance.

Number in front of a chemical.

Matter can not be created or destroyed.

A compound always contains the same elements in the same proportions, regardless of how the compound is made or how much of the compound is formed.

Something that slows or speeds up the reaction.

A protein that is a catalyst for chemical reactions in living things.

Something that supports the reaction.

A balanced state.
