A complete chemical equation represents the reactants, products, and their physical states symbolically.
A chemical equation should always be balanced to ensure the number of atoms of each type is the same on both sides of the equation.
Combination reactions involve two or more substances combining to form a single product, while decomposition reactions involve a single substance breaking down into multiple products.
A process in which substances interact, leading to a change in their chemical composition.
Adjusting the coefficients in a chemical equation so that the number of atoms for each element is the same on both sides.
Reactions where one substance loses oxygen (is oxidized) while another gains oxygen (is reduced).
A reaction that releases heat, resulting in an increase in temperature of the surroundings.
A reaction that absorbs heat, leading to a decrease in the temperature of the surroundings.
A reaction that produces an insoluble compound, known as a precipitate.
