The same number you started with. In every chemical reaction the total number of atoms at the start is the same as the number of atoms at the end.

How many atoms of carbon are present in the reactants?

To determine the number of carbon atoms in the reactants, you need to specify which reactants you are referring to. The number of carbon atoms can vary depending on the chemical equation.


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?

If five atoms of hydrogen are reactants in a chemical reaction, typically all five atoms will be found in the products unless some sort of splitting or rearrangement of atoms occurs during the reaction. It follows the principle of conservation of mass, meaning atoms cannot be created or destroyed in a chemical reaction.


What are three facts about a chemical reaction are provided by a chemical equation?

A chemical equation provides information about the reactants involved in the reaction, the products formed, and the stoichiometry of the reaction (i.e., the relative amounts of reactants and products). It also shows the balance of atoms on both sides of the equation, ensuring the law of conservation of mass is followed.


What must be true about the properties of the reactants and the properties of the products in a 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.


A substance that undergoes change in a chemical reaction is called a what?

A substance that undergoes change in a chemical reaction is called a reactant. Reactants are the starting materials in a chemical reaction that are transformed into products through the rearrangement of atoms.

What happends to the atoms in the reactants in a chemical reaction?

In a chemical reaction, the bonds between the atoms of the reactants break, and new bonds are formed to make the products. The atoms do not change, they are just rearranged.


What occurs to the atoms of reactants in a chemical reaction?

they rearrange to form products


How do new product is form in chemical reaction?

During a chemical reaction atoms of the reactants are relocated to forms the products.


What structures break in reactants?

In a chemical reaction, bonds between atoms are broken in reactant molecules. These bonds can be covalent or ionic bonds, which hold the atoms together in the reactant molecules. When these bonds are broken, new bonds can form between atoms, leading to the formation of products.


A chemical reaction takes place when what?

The atoms of the reactants are rearranged to form new products that are different in chemical composition and properties from those of the reactants.

Is it true that in a chemical reaction reactants are changed into products?

Yes, in a chemical reaction, reactants are transformed into products through the breaking and forming of chemical bonds. This process involves rearranging the atoms of the reactants to create new substances with different properties.


What chemical is formed in a chemical reaction?

A new chemical substance is formed during a chemical reaction by rearranging the atoms of the reactants. The products of a chemical reaction have different properties compared to the original reactants.


What happens to atoms in the reactants during a chemical reaction?

What goes into a reaction and what comes out of a reaction?

Reactantd go into a reaction and the products come out of a reaction. For want of a better expression the atoms in the reactants play 'musical chairs' to form the products. e.g. Hydrochloric Acid and potassium hydroxide are the reactants and potassium chloride and water are the products. HCl(aq) + KOH(aq) = KCl(aq) + H2O(l) Notice how the atoms all move place.


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 happpens to the reactants in a chemical equation?
