chapter 6 Chemical Reactions Jacob Cheatum

A product is the result of a chemical reaction .

A substance or molecule that is in a chemical reaction .

Chemical energy is what is released when a compound reacts with others to form new compounds .

A chemical reaction that releases heat to the surroundings . An example is in a isooctane -oxygen reaction because more energy is released as the products form to break the bonds in the reactants .

Is a reaction that must have heat to take place . Example - hydrated barium hydroxide combined with ammonium nitrate in a flask .

A reaction that requires two or more substances combine to make a new compound .

Is when a compound is broke down to form two or more simple substances .

The process that a electric current is used to make a chemical reaction , such as the decomposition of water .

Is the oxidation of an organic compound and when this happens heat is released .

Is when one of the elements in a compound is replaced by another .

Is when a reaction happens and the positive and negitive ions of the reactants switch places .

Is a chemical reaction in which the oxidation number of a molecule , atom , or ion changes by loosing or gaining electrons .

A atomic or molecular species that has unpaired electrons .

The gaining of electrons

To bond chemically with oxygen

Is the representation of chemical reactions

Compares the moles of one substance to the amount of miles to another substance .

The number in front of a variable

States that mass can not be created or destroyed

States the a chemical compound always contains the exact same proportion of elements .

Increases the rate of a reaction without it going any major changes

Can produce a biochemical reaction .

A substance or layer that is under something happening .

Is when the state in both reactants are present and have no farther tendency to change .
