Unit 3b - Chemical Equation - AP Chemistry

chemical equations

visual representations of the atoms/molecules involved in a chemical reaction

shows the molar ratio “recipe” for all reagents/products

reagents

the chemical(s) you begin with prior to a chemical reaction occurring

typically written on the left side of the equation

products

the chemical(s) you end with after a chemical reaction has occurred

typically written on the right side of the equation

yields/produces

the verbal way of saying a chemical reaction occurs

shown in an equation by the arrow, which points in the direction of the reaction or from reagents to products

conversation of matter

no matter is gained or lost during a chemical reaction

balancing

the use of coefficients to mathematically alter a chemical equation to make sure it abides by the law of conservation of matter

coefficients

the large numbers in front of the chemical formulas

represent the number of moles of each reagent/product present in the reaction

phases

the state of matter each reagent/product is found in during the reaction
