Question 4 and 6 4.) Draw XY3 where X has 5 valence electrons and Y has 7 valence electrons
5.) Draw AB2 where A has 2 valence electrons and B has 7 valence electrons.

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

is there any options? maybe im just not seeing them but i need the options to

catya your not at all which answer i've seen you do this on another question!
