1.Which of these statements about the conservation of mass is not correct?
A. The mass of the products will be equal to the

B. During a chemical reaction, no mass is
created or destroyed.
C. There will be the same number and type of
atoms before and after a chemical reaction.
D. All of the above are correct.

answer; i believe the correct answer is (solid gold);

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
