Use the graph to answer these questions.

Can someone help me with this, please?

The total energy of the reactants is

–3,811.92 kJ.

–1,273.02 kJ.

–2,538.90 kJ.

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).

you need to stop taking that class
