Why don't the amount of reactants and products change in a reversible reaction?

The "amounts" of reactants and products DO change in a reversible reaction. What doesn't change is the concentration of these reactants and products AT EQUILIBRIUM. And also what does not change is the total mass of the system.

When after a chemical reaction do the reactants still exist?
The reactants in a chemical reaction exist before the reaction begins and are consumed during the reaction. Once the reaction is complete, the reactants are typically no longer present. However, in some cases, a small amount of reactant may remain unreacted or there may be reversible reactions where some reactants can be regenerated.
In an exothermic reaction the difference between the chemical energy of the reactants and the chemical energy of the products equals?
The amount of heat given off by the reaction
What factor in reaction rate is related to the amount of reactants?
This is the concentration of reactants.
What are the products and reactants in the primary fusion reaction carried out within the sun?
The reactants are Hydrogen atoms and products are Helium atoms. Because Helium atoms are larger than Hydrogen atom, large amount of energy is released from the net binding energy that resulted during the fusion process.
What does is mean when a system has reached equilibrium?
if there is no motion of a lever around a fulcrum, then how do the torques compare? the torques must be equal. this does not necessarily imply that the forces or the lever arms involved are equal. when this situation occurs we say the lever system is in equilibrium.

Why the amounts of reactants and products do not change in a reversible reaction?
The amount of reactants and products do not change in reversible reactions because, in a chemical reaction, matter is neither created nor destroyed -- it is only rearranged. This is the law of conservation of matter.
Why amount of reactant and product do not change in reversible reaction?
The amount of reactants and products do not change in reversible reactions because, in a chemical reaction, matter is neither created nor destroyed -- it is only rearranged. This is the law of conservation of matter.
When does a chemical reaction reaches equilibrium?
equilibrium means the rate of forward reaction = rate of backward reaction... there are three types of equilibrium 1. amount of products > amount of reactants 2. amount of products = amount of reactants 3. amount of products < amount of reactants
What happens to the mass of reactants in a chemical reaction?
The reactants will form products, so the amount of reactants will decrease, proportionally to the increase in products. The amount can be expressed in mass, concentration or moles.
What does the percent yield of a reaction measure?
It measures the amount of reactants actually produced in a reaction compared to the amount that would theoretically be produced if 100% of the reactants were converted to products according to the stoichiometry of the reaction. It is found by: actual moles of products ÷ predicted moles of products * 100%
What happens to the amounts of reactant and products after a reaction has reached chemical equilibrium?
The "amounts" of reactants and products DO change in a reversible reaction. What doesn't change is the concentration of these reactants and products AT EQUILIBRIUM. And also what does not change is the total mass of the system.
What would happen to the amount of products if you increase the amount of one of the reactants?
Unless the reaction is not using up all of the reactants, adding more of just one cannot increase the amount of the products.

What law is the basis for the amount of reactants and products being equal in each chemical reaction?
Conservation of mass.
In an exothermic reaction the difference between the chemical energy of the reactants and the chemical energy of the products equals?
The amount of heat given off by the reaction
