The sum of mass and energy, the energy being related to mass by Einstein's equation e = mc2, where e is energy, m is mass and c is the speed of light in vacuum.
Enthalpy is not conserved in a closed system undergoing a chemical reaction.
In order for a nuclear reaction to be balanced, there are quantities that must be conserved. The quantities are the atomic numbers and mass numbers of the particles involved in the reaction.
yes
Energy is conserved in a chemical reaction, meaning the total amount of energy before and after the reaction remains constant. This principle is known as the law of conservation of energy.
In a chemical reaction, the total mass and the number of atoms of each element are always conserved. This is known as the law of conservation of mass.
Both mass and charge
Yes. Basically, energy is ALWAYS conserved. The popular saying, that in a nuclear reaction mass is converted to energy, is plainly wrong, since both mass and energy are conserved. Read about "mass deficit", for example in the Wikipedia, for more details.
In a chemical reaction, matter is conserved by the rearrangement of atoms so that the same elements present at the start of the reaction are also present in the products. Energy is conserved through the breaking and forming of chemical bonds, where the total energy before and after the reaction remains the same due to the law of conservation of energy.
Atomic energy is released during a nuclear reaction during fission or fusion. It is released by the nucleus of an atom and can also be a result of radioactive decay.
Yes, mass is conserved in a chemical reaction, including the reaction between zinc and iodine. This principle is known as the Law of Conservation of Mass, where the total mass of reactants is equal to the total mass of products formed.
Energy is conserved in an endothermic reaction because the heat absorbed becomes potential energy. This potential energy isn't lost energy, it's simply stored, instead of being used.
In this reaction, mass is conserved. This means that the total mass of the reactants (N2 and F2) will be equal to the total mass of the products (NF3). Additionally, charge is conserved, ensuring that the overall charge of the reactants is equal to the overall charge of the products.
