The statement that best supports the scientists claim is; The mass of the final product will be equal to the total mass of both reactants, 35.0 grams.
The statement that best satisfies the scientist's claim is that "the mass of the the final product will be equal to the total mass of both reactants, 35g".
The law of conservation of mass states that "in a chemical reactions in isolated systems, mass is neither created nor destroyed ".
This means that there is no mass lost or added when chemical reactions are completed
This means that the mass of reactants and products must be the same and as such the combined mass of the reactant should be that of the product obtained.
