Numerical relationships between compounds in a balanced chemical equation, used to predict product or reactant amounts. Balanced Chemical Equation
A symbolic representation where the number of atoms for each element is equal on both sides, ensuring mass conservation. Reactant
A starting substance in a chemical reaction, present on the left side of a chemical equation. Product
A substance formed as a result of a chemical reaction, shown on the right side of a chemical equation. Coefficient
A number placed before a chemical formula in an equation, indicating the relative amount of each substance. Mole
A unit representing 6.022 x 10^23 particles, used to count atoms, molecules, or ions in chemistry. Stoichiometric Chart
A visual tool guiding the stepwise conversion from given information to unknown quantities in stoichiometric calculations. Mole-to-Mole Comparison
A step using coefficients from a balanced equation to relate the amounts of two substances in a reaction. Given Information
The known quantity or substance provided in a problem, serving as the starting point for calculations. Unknown
The quantity or substance to be determined in a stoichiometric problem, typically the calculation's goal. Gram
A metric unit of mass commonly used to express the amount of a substance in stoichiometric problems. Atom
The smallest unit of an element, which can be counted or converted in stoichiometric calculations. Molecule
A group of atoms bonded together, representing the smallest unit of a compound involved in reactions. Formula Unit
The simplest ratio of ions represented in an ionic compound, used in stoichiometric conversions. Ion
A charged particle, either positive or negative, that may be counted or converted in stoichiometric calculations.
