4C2H5 + 13O2 8CO2 + 10H20
determine the number of moles of O2(g) required to completely
react with 15 moles of C2H5(g) during this 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.
