Question

In the chemical reaction below, sodium (Na) and chlorine (Cl) combine to form sodium chloride (NaCl). 2Na + Cl2 → 2NaCl If the combined mass of the starting reactants is 50 grams, then the mass of sodium chloride formed once the reaction has reached completion A. will be exactly 50 grams. B. will be exactly 100 grams. C. will be between 50 and 100 grams. D. will be less than 50 grams.

Answer 1

Exactly 50 grams

Step-by-step explanation:

The law of conservation of mass states that mass is neither created nor destroyed in a chemical or physical change—it is only rearranged. The combined mass of the starting reactants is exactly 50 grams. So, the mass of sodium chloride formed during the chemical reaction will be exactly 50 grams.

Answer 2

A. Exactly 50 grams matter cant be created or destroyed
