Chemical Reaction

Front

Chemical change; when substances interact with each other. Original substances are used up.

Back

Compound

Front

Any amount of a chemical combination of 2 or more different atoms.

Back

Physical Change

Front

When a substance changes its phase (changes to a solid, liquid , gas, or plasma) or is modified (size, shape, etc) but remains the same substance.

Back

Balanced Equation

Front

Chemical equation where the total mass of the reactants equals the total mass of the products. Produced by changing the coefficients of the compounds.

Back

Chemical Change

Front

Chemical reaction; when substances interact with each other. Original substances are used up.

Back

Reactants

Front

Substances existing before a chemical reaction takes place. Found to the left of the arrow.

Back

balanced

Front

the amount of atoms on the left of the yield sign are the same as the amount of atoms on the right, Law of Conservation of Mass (mass can't be created or destroyed)

Back

coefficient

Front

a small whole number that appears as a factor in front of a formula in a chemical equation

Back

Chemical Equation

Front

Written representation of a chemical reaction/chemical change; shows all the reactants and products. Always in the form of: Reactants arrow Products.

Back

Bubbles

Front

Gas given off during a chemical reaction; may or may not have an odor. Sign of a chemical reaction.

Back

Products

Front

Substance(s) existing after a chemical reaction takes place. Found to the right of the arrow.

Back

chemical equation

Front

a representation of a chemical reaction that uses symbols to show the relationship between the reactants and the products

Back

Molecule

Front

A chemical combination of 2 or more of the same atoms.

Back

Other Signs of a Chemical Reaction

Front

light, heat, color change, new substance exists

Back

reactants

Front

things that react together (on the left side of the equation)

Back

yields

Front

the arrow in the middle of the equation

Back

chemical reaction

Front

the process by which one or more substances change to produce one or more different substances

Back

formula equation

Front

a representation of the reactants and products of a chemical reaction by their symbols or formulas

Back

Subscript

Front

Number written after and BELOW an element in a chemical formula telling you how many of the preceding element are needed for that compound or molecule.

Back

Coefficient

Front

Number in front of a compound's chemical formula telling you how many molecules of that compound are needed.

Back

products

Front

things that are produced (on the right side of the equation)

Back

Law of Conservation of Mass

Front

Mass cannot be created nor destroyed; Mass can only change forms. The total mass of products equals the total mass of the reactants.

Back

Chemical Formula

Front

The symbols and quantities (shown by subscripts) of the atoms needed to make 1 molecule of a substance.
