Using a balanced chemical reaction and a periodic table, which of the following is not possible to calculate?
a. the molar mass of the products
b. the number of atoms in the reaction
c. the number of molecules in the reaction
d. the amount heat produced in the reaction

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).

b.

the accuracy of the data.
