The boiling point of bromine is 59 °C. Which of the following best predicts the boiling
point of iodine monochloride, a polar compound? (4 points)
Lower than 59 °C because ionic bonding in bromine is stronger than covalent bonding in
iodine monochloride.
Higher than 59 °C because dipole-dipole interactions in iodine monochloride are stronger
than dispersion forces in bromine.
Lower than 59 °C because dipole-dipole interactions in iodine monochloride are weaker than
in bromine.
Higher than 59 °C because ionic bonding in iodine monochloride is stronger than H-bonding
in bromine.

Answer asap need to be answered by wednesday morning explain how a buffer works, using an ethanoic acid / sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.

Liquid ammonia is produced at high temperatures and under great pressure in a tank by passing a mixture of nitrogen gas and hydrogen gas over an iron catalyst. the reaction is represented by the following equation. n2(g) + 3h2(g) → 2nh3(g) changing all but one experimental condition will affect the amount of ammonia produced. that condition is a) increasing the concentration of both reactants b) changing the temperature within the tank c) decreasing the pressure within the tank. d) increasing only the amount of nitrogen present.
