What is true about a system in chemical equilibrium? No reactants remain in the system. The amount of product equals the amount of reactant. The amount of reactant changes, but over time remains about the same. There are no products in the system.

When a chemical reaction occurs, the physical and chemical properties of the reactants are the same as the properties of the products the compounds can be separated by physical means O a phase change takes place the physical and chemical properties
