Alexandra decides to climb Mt. Krumpett, which is 5000 m m high. She determines that this will require a total of 3150 kcal k c a l of energy for the trip. For her food supply, she decides to take nutrition bars. The label states that each bar contains 50 g g of carbohydrates, 10 g g of fat, and 40 g g of protein. How many nutrition bars should Alexandra pack?

What is the correct equation for cellular respiration?

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.

The vapor pressure of ethanol is 1.00 × 102 mmhg at 34.90°c. what is its vapor pressure at 61.61°c? (δhvap for ethanol is 39.3 kj/mol.)
