  1. 2. in a balanced chemical equation are the whole numbers placed in front of the chemical formulas to ensure that the equation obeys the law of conservation of mass. They represent the relative quantities of the reactants and products in the reaction.
  2. 3. in the context of a chemical reaction refers to the amount of product(s) obtained in a reaction. It can be expressed as a percentage or a ratio of the actual amount obtained compared to the theoretical maximum amount.
  3. 4. This term is used to describe a substance that is dissolved in water, forming a solution. In chemical equations, it is denoted by "(aq)" after the chemical formula to indicate that the substance is in solution.
  4. 6. the substances that participate in a chemical reaction, and they are shown on the left-hand side of a balanced chemical equation.
  5. 9. states that in a closed system, mass is conserved, meaning that the total mass of the reactants is equal to the total mass of the products in a chemical reaction. This law is fundamental in chemistry and underlies the concept of balanced chemical equations.
  6. 12. This term represents a substance in its liquid state. In chemical equations, it is denoted by "(l)" after the chemical formula to indicate that the substance is a liquid.

  1. 1. is a process in which one or more substances (reactants) are converted into different substances (products) by rearranging their atoms. Chemical reactions can involve the breaking and forming of chemical bonds.
  2. 5. is a representation of a chemical reaction that shows the same number of atoms of each element on both the reactant and product sides. It obeys the law of conservation of mass.
  3. 7. This term represents a substance in its gaseous state. In chemical equations, it is denoted by "(g)" after the chemical formula to indicate that the substance is a gas.
  4. 8. is a form of energy that can be released or absorbed during a chemical reaction. Some reactions are exothermic, releasing heat, while others are endothermic, absorbing heat.
  5. 10. This term represents a substance in its solid state. In chemical equations, it is denoted by "(s)" after the chemical formula to indicate that the substance is a solid.
  6. 11. the substances formed as a result of a chemical reaction. They are shown on the right-hand side of a balanced chemical equation.
