Chemistry 5 grams of cereal was crushed and dissolved in 25 mL water and placed in a dialysis bag. This sample was dialysed over a week in a beaker which contains 500 mL of water. 5 mL of the dialysate (an aliquote from the 500 mL) was separated to determine the glucose concentration. The glucose concentration was determined as 5 mM. Calculate the amount (% w/w) of glucose present in the cereal. Hint: The molecular weight of glucose is 180.
Which of these statements regarding the storage materials is false? Choose from the choices below: LP gas and gasoline has the same specific energy and thus are equally well suited as fuels for a vehicle. The energy density of Li ion batteries is lower because it's another type of storage material. Even though carbohydrates have a lower specific energy than hydrocarbon fuels, their energy density is higher because they are solids. Hydrogen has the highest specific energy, but its energy density is quite low
How many moles of O2 are needed to burn 1.45 mol of C8H18? Express the amount in moles to three significant digits. The complete combustion of octane, C8H18, a component of gasoline, proceeds as follows: 2C8H18(l)+25O2(g)→16CO2(g)+18H2O(g) Relevant volumetric equivalencies 1 gal = 3.785 L 1 L = 1000 mL
One hour of bicycle racing can require 500-900 kcal of energy, depending on the speed of the race, the terrain, and the weight of the racer. Tour de France riders must consume abnormal amounts of food to supply this energy. Food in the form of protein or carbohydrates produces 17.0 kJ of energy per gram consumed. How many kilograms of protein or carbohydrate must be consumed to provide the energy for 195 minutes of racing that requires 650.0 kcal/hr. (Recall 1 kcal = 4.184 kJ)

The recommended daily dose of calcium for an 18-year-old male is 1200 mg. If 1.0 cup of whole milk contains 290 mg of calcium and milk is his only source of calcium source, how much milk should an 18-year-old male drink each day in mL? Suppose the child is lactose intolerant, do some research and explain what type of milk would be a good substitute for the child. Please give mg of calcium per cup of alternative milk value, and show calculations for how much of the alternative milk an 18-year-old male should drink each day in mL. (Hint: 1 cup = 236.588 mL) Show all work. Give numerical answers in 2 significant figures.
A marshmallow is burned in a soda can calorimeter, and heats up 0.255 kg of water by 12.9°C. The calorimeter was calibrated and had a calorimetry constant of 8.50 kcal/kg･°C. Given that carbohydrates contain 4.00 kcal/g, calculate the mass in g of the sugar contained in the marshmallow. Assume that the marshmallow contains no fat or protein.

The air has a dry ball temperature of 34 ° C and a wet bulb temperature of 24 ° C is initially heated in a heater so that the dry ball temperature increases to 90 ° C. Then the air is passed through the pile of corn kernels to dry. The air that comes out of the corn kernels is at 60 ° C. Then this air is passed to the dehumidifier to reduce the RH to 10%. Draw the course of the process of changing the air on the psychometric chart. The airflow rate through the corn kernels pile and dehumidifier is 4.0 m / s and the pile cross-sectional diameter is 0.5 m. a. Determine the amount of moisture lost from the corn kernels pile (in grams of water / second) b. Determine the amount of water lost from the air when passing through the dehumidifier (in grams of water / second)
