Chemical Reactions and Equations Quiz

A chemical reaction is a process in which substances are transformed into new substances, while a chemical equation is a symbolic representation of a chemical reaction.

The law of conservation of mass states that the total mass of the products of a chemical reaction must equal the total mass of the reactants. Mass is neither created nor destroyed in a chemical reaction.

Chemical equations are balanced by adjusting the coefficients of the reactants and products to ensure that the same number of each type of atom is present on both sides of the equation. Balancing is important to satisfy the law of conservation of mass and to accurately represent the chemical reaction.

<p>State symbols in a chemical equation indicate the physical state of each substance involved (e.g., solid, liquid, gas, or aqueous solution). They provide important information about the conditions under which the reaction occurs.</p> Signup and view all the answers
