Chemical reactions involve rearrangement of reactant atoms to make new products in a lab setting or experiment.

Evidence of a chemical reaction in a lab includes the following formations: gas bubbles, water, precipitation, energy change, color change, and change in odor.

A chemical equation involves rearrangement of reactant atoms to make new products in a lab setting or experiment. It involves element and compound symbols, coefficients, and subscripts.

There are five types of chemical reactions: synthesis, decomposition, combustion, single displacement/replacement, and double displacement/replacement.

Chemical equations must be balanced to obey the Law of Conservation of Matter/Mass.

Reactions will continue until one of the reactants (the limiting reactant) runs out.

When the limiting reactant runs out, the remaining reactant is the excess reactant.

Stoichiometry, along with a balanced chemical equation, will help determine the limiting and excess reactants.

In a chemical reaction, you have reactants and products. The reactants are used to create the products.

A chemical reaction has occurred when you see bubbles, water, color change, or a solid form.

Chemical reactions must follow the Law of Conservation of Matter/Mass, which means you have to end with the same amount you started with.

Limiting reactants are what runs out first in a chemical reaction.

Excess reactants are what you have extra of after the chemical reactions stops.

Synthesis reaction is when two reactants make one product.

Decomposition reaction occurs when one reactant is broken down into two products.

Single replacement/displacement reaction is when one element is replaced or substituted with another element.

Double replacement/displacement reaction occurs when parts of two ionic compounds are exchanged, making two new compounds.
