Question

how does the mass of the sodium metal and chlorine gas involved in the reaction compare to the mass of the table salt produced?
o the mass of the sodium metal and chlorine gas combined is equal to the mass of the table salt that is produced.
o the mass of the sodium metal is equal to the mass of chlorine gas used and the table salt produced.
o the mass of the sodium metal and chlorine gas combined is greater than the mass of the table salt produced.
o the mass of the sodium metal and chlorine gas combined is less than the mass of the table salt produced.

Explanation:

Step1: Apply the law of conservation of mass

The law of conservation of mass states that in a chemical reaction, mass is neither created nor destroyed. So, the mass of reactants (sodium metal + chlorine gas) must equal the mass of the product (table salt).

Answer:

C. The mass of the sodium metal and chlorine gas combined is equal to the mass of the table salt that is produced.
