Answer: Fe
Explanation: Fe (Iron) is the only element since it involves only 1 atom. The other options are compounds, since there are more than 2 atoms bonded together.
Answer:
I think iron sorry if its wrong goodluck!
According to boiling point elevation equation:
Δ T = i Kb m
when ΔT (change in boiling point) = 7.10 C°
and i (van't Hoff factor)= 1
and Kb = 0.520
so, by substitution:
7.10 = 1*0.520 *m
m = 7.1 / 0.52 = 13.65 m
