Consider the reaction where barium sulfate can be prepared from 2.76 mol of sodium sulfate and excess barium acetate. Sodium acetate is the other product 1.write the balanced MOLECULAR reaction.
2.write the balanced total ionic equation.
3.write the balanced net ionic equation.

it's c. elements are placed in rows based on how may valencies electrons have.

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).

the answer is c. nacl
