Water, made up of water
A description of a chemical reaction that gives the chemical formulas of the reactants and the products of the reaction. Coefficients indicate the number of each molecule present in the reaction. These coefficients can be changed so as not to violate the Law of Conservation of Mass.
A number or a constant multiplied by a term in an algebraic expression. Coefficients always go first. Or is that "ladies"…?
A chemical reaction between a fuel and oxygen that produces heat and light as well as carbon dioxide and water.
A reaction in which a compound is broken down into simpler compounds or elements.
Also known as a metathesis reaction. A reaction in which two reactants trade partners. Here's an example: AB + CD → AC + BD.
The process of driving an electrical current through a reaction mixture.
A process that absorbs heat.
Exothermic is the term used to describe a reaction that releases heat.
A scientific principle that states that matter cannot be created nor destroyed.
A change that does not transform one substance into another substance, such as freezing or melting. That is to say, no new types of molecules are formed during a physical change.
Cause something to happen prematurely
Fling something down
A molecule that is produced in a chemical reaction. Products are generated by reactants.
The chemicals that are present before a chemical reaction takes place. They react together to produce new chemical compounds. In a chemical equation, reactants are listed on the left hand side of the arrow.
A reaction in which one component of a compound is replaced by a new component. Here's an example: AB + C → A + BC.
An equation that identifies the reactants and products but the equation is not necessarily balanced.
The set proportions in which elements or compounds react with one another.
The formation of a complex product from simpler reactants. Here's an example: A + B → AB.
A decomposition reaction initiated by heat.
An equation in pure word form with no elemental symbols or numbers.
