in order for reactants to be changed into products, there needs to be a chemical change.
For reactants to change into a product, they must undergo a chemical reaction, which involves breaking and forming chemical bonds. This process typically requires an input of energy to overcome the activation energy barrier, allowing the reactants to collide with sufficient energy and proper orientation. Additionally, the presence of catalysts can facilitate the reaction by lowering the activation energy required. Once the reactants interact appropriately, they rearrange to form the resulting products.
At least 2 of the reactants must change their chemical formula.
The mass of reactants is equal to the mass of products.

No, for a precipitate to form, at least one product must be insoluble in the solution. When two soluble reactants combine, they can form an insoluble product known as a precipitate, which will then separate out of the solution.
The mass of reactants must be equal to the mass of products.
given the law of conservation of mass, we now know that the mass of the reactants must equal the mass of the product.
An experiment must have a control to show what would happen if no factors were changed.
All chemical reactions have a common structure. It must have reactants, that are the substances that you have at the beginning, and the product that are the new substances you get at the end.
This isn't answerable without knowing what the chemical reaction is. Some reactions are very easy to initiate - alkali metals and halogens will react with little to no prodding. Others require intermediate reactions.
You cannot change the subscripts in the molecular identities.For example, H2SO4 must remain H2SO4 and not changed to something like H3SO7.Furthermore, the total mass of the reactants must equal the total mass of the products.
Without knowing the specific reaction being referred to, it is impossible to determine the second product. In chemical reactions, the products depend on the reactants and conditions involved. To identify the second product, the specific reaction equation must be provided.
