"A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas."
Understanding how to balance chemical equations, identifying reactants and products, and their stoichiometric coefficients.
Chemical reactions: The process by which substances are transformed into other substances through chemical means.
Balancing chemical equations: The process of ensuring that the number of atoms of each element on both sides of a chemical equation is the same.
Stoichiometry: The quantitative analysis of chemical reactions, including the calculation of relative quantities of reactants and products.
Limiting reactants: The reactant that is completely consumed in a chemical reaction, thereby limiting the amount of product that can be formed.
Percent yield: The percentage of the theoretical yield of a chemical reaction that is actually obtained in practice.
Molar ratios: The ratio of the number of moles of one substance to the number of moles of another substance in a chemical reaction.
Conversion factors: The ratios used to convert between different units of measure, such as mass or volume.
Empirical and molecular formulas: The simplest whole-number ratios of atoms in a compound and the actual formula of a compound, respectively.
Reactant excess and product excess: The amount of reactant or product remaining after a chemical reaction is not fully consumed.
Gas stoichiometry: The calculation of the volume, pressure, or temperature of gases involved in a chemical reaction.
Combination reaction: Two or more reactants combine to form a single product.
Decomposition reaction: A single reactant breaks down into two or more products.
Displacement reaction: An element or ion in a compound is replaced by another element or ion.
Double displacement reaction: The cations and anions of two ionic compounds switch places and form two new ionic compounds.
Acid-base neutralization reaction: An acid and a base react to form a salt and water.
Redox reaction: A chemical reaction in which oxidation and reduction occur simultaneously.
Combustion reaction: A reaction in which a substance reacts with oxygen, often producing heat and light.
Single displacement reaction: One element is displaced from a compound by another element.
Addition reaction: Two or more reactants combine to form a single product.
"The reactant entities are given on the left-hand side."
"The product entities are on the right-hand side."
"A plus sign between the entities in both the reactants and the products."
"The arrow points towards the products to show the direction of the reaction."
"The chemical formulas may be symbolic, structural (pictorial diagrams), or intermixed."
"The coefficients next to the symbols and formulas of entities are the absolute values of the stoichiometric numbers."
