One slice of bread provides you with 50 nutritional calories of energy. if a 1-1b loaf of bread contains 18
slices, how many joules of energy are obtained by eating 1.00 g of bread? (1 nutritional calorie equals 1 kcal
and 1 cal = 4.18 j)

How does the presence of oxygen affect the chemical pathways used to extract energy from glucose?

)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.

What is the measured amount of a product obtained from a chemical reaction?
