Chemical Equations and Definitions

Symbols are one or two letters used to denote elements in chemical notation.
A chemical formula represents a compound through a combination of symbols and numbers that indicate the types and quantities of elements (atoms) present.
Subscripts are small numbers written to the right of a chemical symbol, indicating the number of atoms of an element in a substance; absence of a subscript signifies one atom.
A chemical reaction occurs when substances interact, resulting in the formation of one or more new substances with distinct properties from the original substances.
A chemical equation describes the process of a chemical reaction using symbols and formulas, outlining the reactants and the resulting products.
Coefficients are numbers placed in front of chemical formulas in an equation to show how many molecules of that substance are involved in the reaction.
Reactants are the starting substances in a chemical reaction, represented on the left side of the arrow in a chemical equation.
Products are the new substances created during a chemical reaction, indicated on the right side of the arrow in a chemical equation.
The term "yields" is represented by an arrow (->) symbol in chemical equations, indicating the transformation of reactants into products.
A compound is a substance formed from two or more elements that are chemically combined in a fixed proportion.
Physical change refers to alterations in the physical properties of a substance, without changing its chemical composition.
