atoms are conserved in chemical reactions?
225881
In a chemical reaction the total mass of all the substances taking part in the reaction remains the same. Also, the number of atoms in a reaction remains the same. Mass cannot be created or destroyed in a chemical reaction.

- Atoms of a given element are identical (meaning they have the same mass and properties). - Atoms retain their identity in all chemical reactions.   This is basically the Law of Conservation of matter stating that an equal amount of mass exists before and after a reaction.

The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side. Balancing chemical equations is a process of trial and error.

Reactants and products contain the same atoms, but they are rearranged during the reaction, so reactants and products are different substances.

Law of conservation of mass. No atoms are created or destroyed in a chemical reaction. ... This means that the total mass of the products in a chemical reaction will be the same as the total mass of the reactants .
334387
In a chemical reaction, substances (elements and/or compounds) called reactants are changed into other substances (compounds and/or elements) called products. You can't change one element into another in a chemical reaction — that happens in nuclear reactions.

Every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. Therefore, there must be the same number of atoms of each element on each side of a chemical equation.

Law of conservation of mass means that the number of atoms of the products is more than the number of atoms in the reactants. ... The mass of the products is different than the mass of the reactants.

In chemistry and physics, an atom is the smallest particle of a chemical element that retains its chemical properties. An atom consists of a dense nucleus of positively-charged protons and electrically-neutral neutrons, surrounded by a much larger electron cloud consisting of negatively-charged electrons.

Everything is composed of atoms, which are the indivisible building blocks of matter and cannot be destroyed. All atoms of an element are identical. The atoms of different elements vary in size and mass. ... A chemical reaction results in the rearrangement of atoms in the reactant and product compounds.
298044
In a chemical reaction, atoms are combined, separated, and rearranged to form new compounds, and the atoms that compose these elements exist in whole number ratios.

When chemical reactions occur, the atoms are rearranged and the reaction is accompanied by an energy change as new products are generated. An example of a chemical change is the reaction between sodium and water to produce sodium hydroxide and hydrogen.
1038703
During a chemical reaction no atoms are created or destroyed. The atoms are rearranged. This results in the formation of new substances with different properties to the starting substances.
121673
Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
594293
A chemical reaction is the process in which atoms present in the starting substances rearrange to give new chemical combinations present in the substances formed by the reaction. These starting substances of a chemical reaction are called the reactants, and the new substances that result are called the products.

Yes, every chemical reaction can theoretically be in equilibrium. ... The only thing that stops chemical reactions from being "in equilibrium" is the lack of the proper number of molecules. For a reaction to be in equilibrium, the concentrations of reactants and products must be related by the equilibrium constant.

This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.
