The average heat evolved by the oxidation of foodstuffs in an average adult per hour per kilogram of body weight is 7.20 kJ kg-1 h-1 . Suppose the heat evolved by this oxidation is transferred into the surroundings over a period lasting 1 day. Calculate the entropy change of the surroundings associated with this heat transfer. Assume the weight of an average adult is 80.0 kg. Assume also the surroundings are at T = 298.0 K.
Please show your work, and I will rate you! TWO PART QUESTION A)What is the rate constant of a first-order reaction that takes 277seconds for the reactant concentration to drop to half of its initial value
Carbon oxide (carbon (II) oxide) can be purified of oxygen impurities by having it react with cobalt (II) oxide. If the impure carbon oxide contains a volume of 1.5% oxygen, and if it reacts with cobalt (II) oxide at 250 °C and 500 kPa.
sucrose solution is allowed to react for 195 minutes then determine the mass of sucrose that is hydrolyzed?
Given that translational and rotational degrees of freedom typically behave classically, but vibrations behave quantum mechanically, the total (avg) energy of a diatomic is predicted to be U= (5/2)RT+ , where is obtained from Eq.124.
