X is a metal that is solid under standard conditions. The element bromine is a diatomic liquid under standard conditions. 2X(s) + CaBr, (s) → Ca (s) + 2XBr(s) AH = - 300 kJ/molpxn rxn Ca (s) + ½ Br,(1) → CaBr2 (s) AH,= -675 kJ/mol AH°, °vap of Br2(1) = +29.6 kJ/mol %3D AH°sub of X (s) = +99.5 kJ/mol (a) Write a chemical reaction that would represent the heat of formation of the compound XBr(s) (b) Determine the value AH, of the compound XBr(s). (c) Calculate the AHn for this reaction: 2XBr (s) → 2X (g) + Br2 (g) rxn

Why are ducks waterproof? It’s because they produce copious amounts of oils from their uropygial glands and spread it across their feathers. In this exercise, we’ll be investigating the molecular structure of one of these preen oils to determine how it keeps ducks dry. Q.5 - Preen oil is actually a complicated mixture of many different organic compounds, such as the structure seen previously.. Ornithologists have determined that birds often use preen oil compounds for scent recognition. Below, several different chemicals isolated from preen oil are shown, along with their vapor pressures at room temperature. p-cymene has the highest vapor pressure, meaning it is the most easily evaporated compound of the three listed. Explain why p-cymene has a higher vapor pressure at room temperature compared to the other compounds. Make sure to explain what holds the p-cymene in the sample. (Image attached)
