Watch the animation, then check off the samples that will conduct electricity. check all that apply. view available hint(s) check all that apply. nacl solution solid nacl solid sugar sugar solution

NaCl solution

Explanation:

The only one fmor the options that could conduct electricity would be the NaCl solution, the other ones, the solid NaCl or the Solid Sugar wouldn´t be able to conduct electricity because the molecules on it wont allow electrons to pass, while sugar solution wont allow electrons to pass through the solution, sp the only one from the options tha would actually let electrons through the solution and conduct electricity would be NaCl solution.

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
