The Law of Conservation of Mass tells us that the reactant(s) and product(s) of a chemical reaction must have the same weight. This can sometimes confuse us in the example of :
I start out with wood(reactant), when it's completely burnt the ash(product) doesn't weigh the same.
This is because ash isn't the only product. There are other products that have gone into the air that we can no longer weigh. But if they were still available to us, the ash plus the other products would weigh the same as the wood.
I've just been learning about the same thing in my grade 10 chemistry class. Sorry if my example confused you, if it did don't pay attention to it :P

What else can I help you with?
What is it called when the mass of the rreactants equals the mass of the products?
It is called the Law of Conservation in Mass.!
What law states that mass cannot be created or destroyed in chemical or physical changes?
The law that states mass cannot be created or destroyed in chemical or physical changes is the Law of Conservation of Mass, also known as the Principle of Mass Conservation. This law implies that in a closed system, the total mass remains constant before and after any chemical or physical process, even if the substances undergo a change in form or state.
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.
Why is the law of conservation of mass used and give Background of the law of conservation of mass?
The law of conservation of mass states that mass in an isolated system remains constant over time. It is used to understand chemical reactions and physical processes where mass is conserved. The law was developed by Antoine Lavoisier in the 18th century as a fundamental principle of chemistry, leading to the modern concept of conservation of mass-energy.
Defin the law of conservation of mass?
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. In other words, the total mass of the reactants must equal the total mass of the products in a chemical reaction. This principle is also known as the law of conservation of matter.
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 is it called when the mass of the rreactants equals the mass of the products?
It is called the Law of Conservation in Mass.!
What law states that mass cannot be created or destroyed in chemical or physical changes?
The law that states mass cannot be created or destroyed in chemical or physical changes is the Law of Conservation of Mass, also known as the Principle of Mass Conservation. This law implies that in a closed system, the total mass remains constant before and after any chemical or physical process, even if the substances undergo a change in form or state.
State the principle that explains why there must be the same number of atoms of each element on each side of an equation?
The principle is the Law of Conservation of Mass, which states that matter cannot be created or destroyed in a chemical reaction. Therefore, the number of atoms of each element on each side of a chemical equation must be the same to ensure that mass is conserved.
What law states that the mass can not be lost or gained in a chemical reaction?
The law that states that mass can neither be created nor destroyed in a chemical reaction is the Law of Conservation of Mass, also known as the Law of Mass Conservation. This principle was first formulated by Antoine Lavoisier in the late 18th century and is a fundamental concept in chemistry.
What principle that states that matter cannot be created nor destroyed is?
The principle that states matter cannot be created nor destroyed is the law of conservation of mass. This scientific principle is also known as the law of conservation of matter. It states that in a closed system, the total mass remains constant before and after a chemical reaction or physical change.
What is the principle of conservation of matter?
It may also be known as the law conservation of mass; and it states that the total mass of materials present after a chemical reaction is the same as the total mass before the reaction. This law is the basis for Dalton's postulate 3.
The principle stating that matter is not created or destroyed during a chemical reaction?
law of conservation of mass
How are the law of conservation of energy and the law of conservation of mass similar?
In both cases, something is conserved - it doesn't change over time.Also, mass and energy are equivalent. If something has energy, it has mass, and vice versa.
Is stoichiometry is based on the law of conservation mass?
Yes, stoichiometry is based on the law of conservation of mass, which states that mass can neither be created nor destroyed in a chemical reaction. This principle forms the foundation of stoichiometry calculations, which involve determining the quantities of reactants and products in a chemical reaction based on the conservation of mass.
What is the Law of Conservation of Mass.?
During chemical processes in a closed system the mass remain constant.
What law represents a balanced chemical equation?
The law of conservation of mass, which states that in a closed system, mass is neither created nor destroyed, it can only change form. This means that in a chemical reaction that takes place in a closed system, the mass of the reactants equals the mass of the products.
