a representation of a chemical reaction that uses symbols to show the relationship between the reactants and the products.
4 Indications of a chemical reaction
precipitate, change in color, increase or decrease in temperature, and/ or production of gas.
A number in front of a chemical formula in an equation that indicates how many molecules or atoms of each reactant and product are involved in a reaction.
a substance that initiates or accelerates a chemical reaction without itself being affected
separation of a substance into two or more substances that may differ from each other and from the original substance
A reaction in which one element or radical takes the place of another element or radical in a compound
a reaction in which a gas, a solid precipitate, or a molecular compound forms from the apparent exchange of atoms or ions between two compounds
a chemical reaction that occurs when a substance reacts with oxygen, releasing energy in the form of heat and light
the relation between the quantities of substances that take part in a reaction or form a compound (typically a ratio of whole integers)
the sum of the average atomic masses of all the atoms represented in the formula of any molecule, formula unit, or ion
a chemical formula showing the ratio of elements in a compound rather than the total number of atoms
the relative number of moles of the substances required to produce a given amount of product in a chemical reaction
the substance that controls the quantity of product that can form in a chemical reaction
the maximum amount of product that can be produced from a given amount of reactant
