For the next three questions, assume that the reaction below occurs in water; consult the Solubility Table when needed. Balance the equation. Show the net ionic equation. Identify the physical state
for each species using “aq” or “s."
Pb(NO3)2 + Na2S → PbS + 2 NaNO3

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).
