What does Mass and atoms are conserved in every chemical reaction but moles are not NecEssaRily conserved?

Because of the different weights of moles of different elements there can always be different amounts of moles after a chemical reaction. Ex. if i have 3 pounds of apples and 1/2 a pound are rotten then 3 days later another 1/2 pound goes rotten i still have 3 pounds in the end but i have different amounts of each type.First i had 2 1/2 good apples and 1/2 pound bad apples. but then 3 days later i have 1 pound of bad apples and 2 pounds of good apples. no neccesarlily changing the amount or atoms but the type and placment of each. the same concept can be applied to moles of elements after a chemical reaction

What is always conserved in a chemical reaction?
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.
Why the the number of atoms conserved but the number of molecules is not in a chemical equation?
In a chemical equation, the number of atoms is conserved because atoms cannot be created or destroyed during a chemical reaction due to the law of conservation of mass. However, the number of molecules is not necessarily conserved because molecules can be broken apart or formed during a reaction, resulting in a change in the number of molecules involved.
How is matter and energy conserved in a chemical reaction?
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.
What is conserved when one balances a chemical equation?
When balancing a chemical equation, the number of each type of atom on the reactant side must be equal to the number of each type of atom on the product side. Mass and charge are conserved during a chemical reaction as well.
How does a chemical equation show that matter is always conserved in a chemical reaction?
According to the Law of Conservation Of Mass,Matter is neither created nor destroyed.It means a chemical equation show that matter is always conserved in a chemical reaction.It is shown as number of atoms both sides of the reaction before and after remains the same.
If five atoms of hydrogen are reactants in a chemical reaction then how many atoms of hydrogen will be found in the products of that reaction?
Mass is conserved in a chemical reaction, so the mass before must equal the mass after. If you have five atoms before, you must have five atoms after.
Ions that do not change in a chemical reaction is?
Spectator ions do not change in a chemical reaction as they appear in the reactants and products in the same ionic form. They do not participate in the reaction and are typically omitted when writing net ionic equations.
What is conserved when one balances a chemical equation?
When balancing a chemical equation, the number of each type of atom on the reactant side must be equal to the number of each type of atom on the product side. Mass and charge are conserved during a chemical reaction as well.

In any chemical reaction the quantities that are preserved are?
In any chemical reaction the quantities that are conserved are mass and number of atoms. After the correct formula for a reactant in an equation has been written, the formula should not be changed.
What is conserved in the reaction shown below. N g plus 3F g 2NF g?
Mass is conserved in any chemical reaction. If the reaction is balanced it will show that mass is conserved. In others words the mass of the reactants will equal the mass of the products...just to add the balanced reaction should be (i didn't know if you forgot the subscripts or not): N2 + 3F2 --> 2NF3 so is it atoms only mass only mass and atoms only or moles only
What happens to total amount of mass in chemical reaction?
The total amount of mass remains constant in a chemical reaction, according to the law of conservation of mass. This means that the total mass of the reactants will equal the total mass of the products formed in the reaction. Mass cannot be created or destroyed in a chemical reaction, only rearranged.
What happeneds to atoms in a chemical reaction?
Chemical reactions occur when different atoms and molecules combine together and spit apart. For example, if Carbon (C) is burnt in Oxygen (O2) to form Carbon Dioxide, a Chemical Reaction occurs.So, during chemical reactions, new product atoms are not created, and old reactant atoms are not destroyed. Atoms are rearranged as bonds are broken and formed. In all chemical reactions, mass is always conserved...In chemical reactions, atoms rearrenge to form products...During chemical change atoms arrange and form new bonds. The new bonds are form to make the products.
Why do reactants in a chemical reaction weigh exactly the same as different products at the end of a reaction?
Energy may only be transformed from one sort to another. Mass is a form of Energy and as such, must be, and is, conserved. It is 'of no surprise' then, that the number of atoms that enter a chemical reaction is equal to the number of atoms that exist after the reaction has been completed.
Can atoms be divided by chemical reaction?
No, this would be contrary to the definition of an ordinary chemical reaction.
Why do reactions have to he balanced?
atoms are not lost or gained in a chemical reaction
A balanced chemical equation allows you to determine the?
A balanced chemical equation allows you to determine the ratio of reactants consumed and products produced in a chemical reaction. It also allows you to calculate the amounts of substances involved in the reaction based on the stoichiometry of the equation.
