Standard 5:Chemical Nomenclature, Reaction Types, and Yield

Chemical Reaction

• a process that occurs when two or more molecules interact to form a new product(s)

• a reaction in which a change to the physical properties of a material or substance occurs.

Reactants

• chemical substances that react together to form a new substance during a chemical reaction.

• a particle of matter that uniquely defines a chemical element.

Products

• is a pure substance made up of two or more elements.

• a substance that is present at the end of a chemical reaction.

Synthesis Reaction

• the study of the chemicals, chemical reactions and interactions that take place in living organism

• occurs when two or more reactants combine to form a single product.

Decomposition reaction

• occurs when two or more reactants combine to form a single product.

• the process or effect of simplifying a single chemical entity into two or more fragments.

Single replacement/displacement reaction

• a reaction in which one element is substituted for another element in a compound.

• two ionic compounds that are exchanging anions or cations

Double replacement/displacement reaction

• when parts from 2 compounds switch places

• a reaction in which one element is substituted for another element in a compound.

Combustion Reaction

• a reaction in which a change to the physical properties of a material or substance occurs.

• a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat.

Chemical equation

• describes how a trait or allele changes in frequency over time.

• symbolic representations of chemical reactions in which the reactants and the products are expressed in terms of their respective chemical formulae.

Coefficients

• a number placed in front of a chemical symbol or formula.

• • an ionic compound whose charge is neutralised. It combines ions with a positive charge with those of a negative one.
