How does the mass of the product in a chemical reaction compare with the mass of the reactants?

The mass of the products should equal the mass of the reactants.


What is the total mass of the reactants compared to the total mass of the product?

They're equal.


What is the principle called of the conservation of mass?

The principle of conservation of mass states that in a chemical reaction, the total mass of the reactants must equal the total mass of the products.


What if the total mass of the product in a chemical reaction is 14grams what must the combined masses of the reactants be?

The mass of reactants is equal to the mass of products.


When two element chemically react the mass of the product is?

After the law of mass conservation the mass of reactants is equal to the mass of products.This is a extremely important law in chemistry.The Russian chemist Mikhail Lomonosov described this principle in 1748.


How does mass of the reactants compare with the mass of the products?

In a chemical reaction, the total mass of the reactants is always equal to the total mass of the products. This is known as the law of conservation of mass. This means that no mass is gained or lost during a chemical reaction.


In an ordinary chemical reaction the mass of the product you?

In an ordinary chemical reaction, the mass of the product is equal to the mass of the reactants. This is known as the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction, only rearranged.


What is true of the total mass of reactants compared to the total mass of product?

According to the law of conservation of mass, the total mass of reactants in a chemical reaction is equal to the total mass of products. This means that no mass is gained or lost during a chemical reaction.


The correct terms for the two sides of a chemical equation?

given the law of conservation of mass, we now know that the mass of the reactants must equal the mass of the product.


This is not lost in a chemical reaction?

Matter is not lost in a chemical reaction, as the total mass of the reactants is always equal to the total mass of the products. This principle is known as the law of conservation of mass.


Which scientific law predicts that the mass of the reactants before a chemical reaction will equal the mass of the products after the reaction has taken place?

The law of conservation of mass, also known as the principle of mass conservation or Lavoisier's principle, states that matter is neither created nor destroyed in a chemical reaction. This means that the total mass of the reactants must equal the total mass of the products in a closed system.


What chemical eaaquations are balanced?

When the mass of reactants is equal to the mass of reactants an equation is balanced.
