Both of the sulfur-oxygen double bonds in so2 are polar. in which direction should the polarity arrows point?

Answer is: the polarity arrows should go from sulfur (S) to the oxygen (O).

The magnitude of the dipole depends on the difference in the electronegativies and has direction from positively charged atom to negatively charged atom.

Oxygen has greater electronegativity than sulfur, because of that oxygen (χ=3.5) is partially negative and sulfur (χ=2.5) is partially positive.

Electronegativity (χ) is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

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
