The starting substances that undergo change in a chemical reaction

The substances produced as a result of a chemical reaction

• Elements that appear as Diatomic molecules in nature must be present as the
• diatomic, not single atoms in a chemical equation: H₂, O₂, N₂, F₂, Cl₂, Br₂, I₂

Mass is neither created nor destroyed in an ordinary chemical reaction

A representation for a chemical reaction that uses chemical symbols and chemical formulas instead of words to describe the changes that occur in a chemical reaction.

A chemical reaction that has the same number of atoms of each element involved in the reaction on each side of the equation

A number placed to the left of a chemical formula in a chemical equation that changes the amount but not the identity of a substance.

A chemical reaction in which a single product is formed from two or more reactants

X + Y → XY

A chemical reaction in which a single reactant is converted into two or more substances

XY → X + Y

A chemical reaction in which one element within a compound is replaced by another element

X + YZ → Y + XZ

A Chemical Reaction in which two compounds exchange parts with each other and form two new compounds

AX + BY → AY + BX

A chemical reaction in which a substance reacts with Oxygen (usually from air) that proceeds with evolution of heat and usually also a flame.

The study of quantitative relationships among reactants and products in a chemical reaction

The reactant in a chemical reaction that is entirely consumed during them chemical reaction

The maximum amount of a product that can be obtained from given amounts of reactants in a chemical reaction if no losses or inefficiencies of any kind occur

the amount of a product actually obtained from a chemical reaction

the ration of the actual yield in a product to its theoretical yield, multiplied by 100 (to give percent)
