Substance mean during a chemical reaction is that they change because not all substance will not stay the same. Like the atom just combines together to make a chemical reaction and that's what substance mean. Also When you interact during a chemical reaction it changes it and it doesn't stay the same

i think when substances interact its like, they are mixing and chemical reaction. like the baking soda and viniger experiment

During a chemical change, a substance change into a one or more different substances. A produces new substances

# data[].attributes.body
It means when substances interact during a chemical reaction when it merges together . It rearranged the atoms around

Chemical reactions involve breaking chemical bonds between reactant molecules (particles) and forming new bonds between atoms in product particles (molecules). The number of atoms before and after the chemical change is the same but the number of molecules will change.

It would create a new product like same substances it would have to same chemical reaction but if itś a new substance interacting with the other substance will create a new product.

When substances have a chemcal reaction the    atoms just merge.  A good example of a cheamcal reactions

what I think it means fora substance to interact during a chemical reaction  bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

# data[].attributes.body
In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

Chemical reactions involve breaking Chemical bond between reactant. The substances that go into chemical reaction are called the reactants,

What I think it means for substance to interact during a chemical reaction is when the particles is forming new bond between atoms and molecules

Chemical reactions involve breaking chemical bonds between reactant molecules and forming new bonds between atoms in product particles.
