Which of the following statements correctly compares and contrasts the reactants with the resulting products used in a chemical equation? A. The reactants are dangerous and the product can be eaten
B. The reactants and the products observe the law of conservation of mass
C. The reactants are a solid and a gas and the product is a gas

B. The reactants and the products observe the law of conservation of mass

Explanation:

The reaction equation is given as:

            2Na  +  Cl₂  →   2NaCl

Such a chemical reactions usually obeys the law of conservation of mass. The law states that "in a chemical reaction, matter is neither created nor destroyed but bonds are rearranged".

So, the most correct thing is that reactants and products observe the law of conservation of mass. The number of atoms on both sides of the expression will be the same. Therefore, option B is correct.

The correct answer for this question is that a statement that can be proven by observation or measurement is known as a fact. The other possible answers here simply refer to idea that different individuals can place value on, but that are not necessarily known to be true.
