What is the ‘structural formula’ of ammonia ?! brainliest answer

Ammonia is a colorless, alkaline gas which is formed when organic substances are decomposed in the body during different reactions.

You have asked for the structural formula which shows the arrangement of the molecules in a compound, but since I cannot draw it here so I will explain in words and hope to make it clear.

Ammonia consists of molecules of nitrogen and hydrogen in the ratio 1:3. Therefore its chemical formula is NH[3]. Its structural arrangement shows one atom of Nitrogen (N) bonded with three atoms of Hydrogen (H).

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g
