If 54.0 grams of water are mixed with excess magnesium nitride, then how many moles of ammonia [NH3] are produced? Mg3N2 (s) + 6H2O(l) → 2NH3 (aq) + 3Mg(OH)2 (s)

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).

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a
