Matter is never lost or gained in a chemical reaction. A chemical reaction cannot destroy or create atoms, it merely rearranges how they are connected and arranged in new molecules.
While the atoms rearrange, energy is released (such as through light, fire or heat), or absorbed, (such as when plants use sunlight to make sugar out of carbon and water). Some atoms may evaporate, making the resulting product seem lighter or smaller, such as when coal or wood burns, but the atoms themselves are not destroyed.
The law of conservation of mass states that in a chemical reaction, mass is neither created nor destroyed - it is conserved. This means that the total mass of reactants must equal the total mass of products in a chemical reaction.
Indeed by the Law of Conservation of Mass, mass cannot be lost or gained through a reaction. Similarly, atoms cannot be lost, gained or somehow transformed themselves-only rearranged into different compounds. This means there are still going to be the same amount of Hydrogen atoms after a reaction as there were before.
The Law of Conservation of Mass applies to chemical changes. When considering a chemical change this would mean that the total mass of all of the reactants in the chemical reaction is equal to the total mass of products in the chemical reaction.
The reactants and the products must contain the same numbers of the same types of atoms, that is, atoms with the same atomic number, and either the products must contain at least one type of chemical bond distinct from any chemical bond in the reactants or the reactants must contain at least one type of chemical bond not found in the products.
An ion can have a positive charge (cation) if it has lost electrons, or a negative charge (anion) if it has gained electrons. The charge of an ion is determined by the number of electrons it has gained or lost during the process of ionization.
Electrons are the ones gained or lost in a chemical reaction. Electrons are gained in oxidation and lost through the chemical reaction known as reduction.
atoms are not lost or gained in a chemical reaction
In a chemical process, matter is not lost nor gained; it is simply rearranged into new combinations. This is known as the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction, only converted into different forms.
No weight is ever gained or lost in a chemical reaction.
The kinds of atoms and the number of each kind are the same on both sides of a balanced chemical equation.
Elements cannot be lost/gained: this is the law of mass conservation.
No, hydrogen is gained during a reduction reaction, not lost. Reduction involves the gain of electrons and hydrogen atoms.
if you balanced the equation correctly then the sum of the reactants will equal the sum of the the products because if there is the same amount of atoms on the reactants and the products obviously none is lost.
matter is never destroyed by reactions created by chemical More specifically, both mass and energy cannot be created or destroyed in any chemical reaction, but mass and energy are equivalent under Einstein's theory of special relativity, so energy can change to mass and vice-versa in the ratio E = mc2
Matter and Energy
There is zero NET loss or gain of electrons
Valence electrons can be both lost and gained during a chemical reaction, depending on the types of elements involved. For example, in ionic bonding, valence electrons are typically lost or gained to achieve a full outer shell. In covalent bonding, valence electrons are shared between atoms to complete their outer shells.
