an object or is placed close to a thin converging lens. The diagram represents three way from the top of all passing through that lens. Which option is correct A, B, C or D? I need to know why the medians differ relative to the data set and the best measure of center? When did the Buffalo Soldiers start and end? 6. The acid strength of the oxyacids of chlorine is as follows:HCIO4 > HCIO3 > HCIO2 > HCIO Which statement best explains this trend?(A) The electrons in the H-O bond are pulled away fromthe hydrogen by the more electronegative oxygen, mak-ing the bond weaker. Additional oxygen atoms intensifythis effect, making the H-O bond even weaker andincreasing the degree of ionization.(B) Oxygen is less electronegative than hydrogen. Addi-tional oxygen atoms provide greater repulsion of theelectrons and cause them to be even closer to the hydro-gen atom, making the H-O bond weaker and increasingthe degree of ionization.(C) Extra electrons are always attracted to the central atomin a molecule. With more oxygen atoms, additional elec-trons are transferred to the chlorine atom. This weakensthe H-O bond and increases the degree of ionization.(D) Oxygen has six valence electrons. Each oxygen atomneeds two additional electrons to fulfill its octet. Theseelectrons are pulled from the H-O bond and cause theacid to ionize. More oxygen atoms require more elec-trons, so the degree of ionization increases. Reeta has spent 2/7 of her salary on car repair work. She has 15. 000 rupees left with her. What is her salary?

Chapter 5 of "The Long Way Gone" Commenting on how a rebel Soldier had interrogated an old man Ishmael writes "Before the war a young man wouldn't have dared to talk to anyone older in such a rude manner.
