Acertain substance condenses at a temperature of 123.3°c . but if a 65.0 gm sample of x is prepared with 24.6g of urea ((nh2)2co) dissolved in it, the sample is found to have a condensation point of 124.3°c instead.
1. calculate the molal boiling point elevation constant kb of x . round your answer to significant digits.

Many free radicals combine to form molecules that do not contain any unpaired electrons. the driving force for the radical–radical combination reaction is the formation of a new electron‑pair bond. consider the chemical equation. n(g)+no(g)⟶nno(g) n(g)+no(g)⟶nno(g) write lewis formulas for the reactant and product species in the chemical equation. include nonbonding electrons. n(g)n(g) select draw rings more erase select draw rings more erase select draw rings more erase n no(g)
