QUESTION 1 Fatty acids are stored in the body as triglicerides in adipose tissues. Consider the oxidation reaction for fatty acids with oxygen (CH3-(CH2)n- COOH + 02 = C02 + H20). Balance this equation for n = 10 and calculate how %3D many ml of metabolic water will form from the oxidation of 636 grams this fatty acid. Assume that 1 ml water has a mass of 1 gram. Calculate your answer to two decimal places, do not specify the units in your answer. NB the comma seperates thousands, the dot is for decimals.

 

QUESTION 2 What is the strength of the ionic interactions between an ion with 1 positive charges and an ion with 1 negative charges, when the distance between them is 13.0 nanometers and the solvent is benzene, with a dielectric constant of 4.6? Calculate answer to 7 decimal places. Do not specify units in the answer.

 

QUESTION 3 Calculate the osmotic pressure for a solution that is 0.2 molar in sodium chloride and 0.7 molar in glucose at 35 °C.
