Why does the number of atoms coming out of a chemical reaction have to equal the number of atoms going into a chemical reaction?
Both sides of a chemical equation must balance due to the law of "Conservation of Mass" which states that in a reaction no matter is created or destroyed. The mass of the reactants must equal the mass of the products.
Eg.
Methane (CH4) combustion (reaction with oxygen)
CH4+2O2 = 2H2O+CO2
Reactants
1 Carbon atom
4 Hydrogen atom
4 Oxygen atoms
Products
1 Carbon atom
4 Hydrogen atom
4 Oxygen atoms
Here the reactants and products have the same mass which replicates what happens in nature

What else can I help you with?
When a chemical reaction is balanced what number appears?
You think probable to the number of molecules or atoms.
Do the numbers of atoms increase or decrease after the chemical reaction?
Yes, in chemical reactions atoms are neither created nor destroyed, nor changed from one kind to another. Those things can only happen in nuclear reactions. Chemistry deals with how atoms combine with one another.
What chemical equation shows that no atoms are lost during a chemical reaction?
The law of conservation of mass states that no atoms are lost during a chemical reaction. This can be represented by a balanced chemical equation, where the number of atoms of each element remains the same on both sides of the reaction. For example, the equation for the reaction between hydrogen gas and oxygen gas to form water is: 2H2 + O2 -> 2H2O.
In a chemical reaction the number of atoms of reactants and products must?
I know that this probably isn't the answer that you were looking for but its a start the answer to this question is one of four different answers choose the one that you think is right. A) The same as the number of atoms in the reactants B) Less than the number of atoms in the reactants C) Greater than the number of atoms in the reactants D) The same as the number of molecules in the reactants
What happens to the atom in a chemical reaction to the product side?
In a chemical reaction, atoms are rearranged to form new compounds or molecules. The atoms present in the reactants combine to form the products of the reaction through breaking and forming new chemical bonds. The total number of atoms remains the same on both the reactant and product sides, following the law of conservation of matter.
Does the number of atoms entering the reaction stay the same as the number put out by the reaction?
In a balanced chemical reaction, the number of atoms entering the reaction as reactants is equal to the number of atoms leaving the reaction as products. This is because of the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction.
How many potassium atoms are in the reactants of the chemical reaction?
To determine the number of potassium atoms in the reactants of a chemical reaction, you would need to look at the chemical equation for the reaction and count the number of potassium atoms on the reactant side. The coefficient in front of the potassium-containing compound in the reactants indicates how many potassium atoms are present in that compound.
Does a chemical equation show the number of atoms lost during a chemical reaction?
Yes, a chemical equation shows the number of atoms of each element involved in a chemical reaction, including those gained, lost, or rearranged. The Law of Conservation of Mass states that mass is conserved in a chemical reaction, so the total number of atoms before and after the reaction must be the same.
What happens to the atoms in a chemical reaction?
During a chemical reaction, atoms are rearranged and bonded together in new ways, forming different substances. The total number of atoms remains the same before and after the reaction, as atoms are neither created nor destroyed in a chemical reaction.
When a chemical reaction is balanced what number appears?
You think probable to the number of molecules or atoms.
What happens to the individual atoms in a chemical reaction?
Individual atoms in a chemical reaction are rearranged to form new chemical compounds. Atoms are not created or destroyed in a chemical reaction, only the way they are arranged changes. The total mass and number of atoms of each element involved in the reaction remain constant, following the law of conservation of mass.
What is the law in a chemical reaction the number of atoms present in the reactants is always equal to the number of atoms present in the products?
This is known as the Law of Conservation of Mass, which states that matter cannot be created or destroyed in a chemical reaction. Therefore, the total number of atoms in the reactants must be equal to the total number of atoms in the products.
Why do reactions have to he balanced?
atoms are not lost or gained in a chemical reaction
What must happen for a chemical equation to be balanced?
The number of atoms, along with the number of different types of atoms, input into the chemical reaction will and must equal these numbers at the Fin of the R'xn.
What chemical equation shows that no atoms are lost during a chemical reaction?
The law of conservation of mass states that no atoms are lost during a chemical reaction. This can be represented by a balanced chemical equation, where the number of atoms of each element remains the same on both sides of the reaction.

What are the number of atoms that make up the molcules on the reaction side and the number of atoms that make up the molecules on the product side?
They are equal. Sometimes referred to as conservation of matter in a chemical reaction.
