it is a law.
Mass can neither be created nor be destroyed but it can change from one state to another state. In a nuclear reaction (power station, nuclear bomb) small quantities of mass are converted into energy. The sun and most stars are routinely steadily decreasing in mass as it is converted into radiation.
In a chemical reaction, the total mass of the reactants is always equal to the total mass of the products.
A change in mass is not always an indicator of a chemical change because mass is conserved in chemical reactions. The total mass of the reactants is equal to the total mass of the products. However, there are some exceptions where a change in mass can occur due to the release or absorption of gases or changes in the physical state (such as evaporation or condensation) during a chemical reaction.
it is neither. no chemical reaction or physical change (melting boiling etc) can change net mass only nuclear reactions change the over all mass by converting mass to energy via Einstein's famous E=MC^2 equation
Energy is neither created or destroyed.
Matter can not be created or destroyed in a chemical or physical change. Which is known as the Law of Conservation of Mass. Matter can only be converted, this conversion happens during a chemical change.
it is a law.
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.
The law of conservation of matter, means you cannot create or lose energy. Energy is only transformed. When you run, your body turns chemical energy into mechanical energy that you to run. When you run, you produce heat, which is an energy
Mass can neither be created nor be destroyed but it can change from one state to another state. In a nuclear reaction (power station, nuclear bomb) small quantities of mass are converted into energy. The sun and most stars are routinely steadily decreasing in mass as it is converted into radiation.
Scientists call this law the law of conservation of matter
starting substances and substances called products
a matter that cant be created or destroyed. it can change form but have a fixed volume.
The law of Conservation of Mass states that mass is neither created nor destroyed. This applies to Chemical Equations because Chemical Equation can not create nor destroy mass or energy. (Equations must be balanced).
In a chemical reaction, the total mass of the reactants is always equal to the total mass of the products.
This law was given by A.Lavoisier in 1774. It stated that mater can neither be created nor be destroyed in a chemical reaction. However it may change from 1 form to another.
