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
