The table shows the melting points of different compounds containing the element bromine. Compound Melting point (°C) MgBr2 711 LiBr 550 AgBr 432 CBr4 91 PBr3 −41 HBr −87 Which of the following statements are supported by the data? Select all that apply. A. All of the compounds exist in the solid state at 25°C. B. The compounds in which bromine bonds with a metal have higher melting points than the compounds in which bromine bonds with a nonmetal. C. The compound with the highest melting point is made up of ions held together by ionic bonds. D. The compound with the lowest melting point is made up of molecules held together by intermolecular attractions. E. The melting point of CBr4 suggests that it can be classified as an ionic compound. F. It takes more energy to overcome the attractive forces between particles of solid LiBr than it does to overcome the attractive forces between particles of solid PBr3.

B) These materials would have very high boiling points.

Upon formation of an ionic bond, two ions with opposite charges have to come together due to the attraction of opposite charges. Ionic compounds have quite strong electrostatic forces of attraction between it's ions. Having strong forces of attraction between compounds in turn means that a lot of energy has to be put in to overcome these attractive forces, and break the individual ions apart. For this reason, ionic compounds will have higher boiling points.

in a place once known as north america, now known as panem, is a very rich city surrounded by twelve districts. every year because this very rich city, known as the capitol, is so rich and likes to think they control all the districts - which they do - there is something known as the hunger games! this is where two children, one boy and one girl from each district from the ages of twelve to eighteen, have to leave their families and compete in the hunger games, a live event that is aired on tv's all over panem. when katniss everdeen, aged sixteen from district 12, has to volunteer to take the place of her twelve-year-old sister prim after prim's name is called forth to become the 23rd member to compete in the 74th hunger games, she promises to prim that she will win! katniss doesn't believe she's coming out alive - but she's not going down without a fight.

because district 12 is so poor, katniss has been close to death many times from starvation but she's made it through it. but this is a different kind of close to death; this katniss doesn't know if she can survive.

she doesn't want to hurt, or kill anyone but when it comes down to it katniss' instinct is to survive. but when she starts to have confusing feelings about the boy from her district who is also her fellow contender, things get worse, and then she teams up with the girl from district 11 and only one person can survive. but who will it be? will her feelings get the better of her? will she let someone else win so they don't have to die? if katniss is going to win she's going to have to be brutal. she's going to have to kill!
