Calculate the relative masses of the following atom (a) CaCo (C = 12, ca = 40, 0 = 16)
(b) H, O (H = 1,0 + 16)​

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).

fe 55.85 g/mol and h2o 18.02 g/mol.
