61. Suppose a highly trained athlete consumes oxygen at a rate of 70.0 mL/(min · kg) during a 30.0-min workout. If the athlete’s mass is 78.0 kg and their body functions as a heat engine with a 20.0% efficiency, calculate (a) their metabolic rate in kcal/min and (b) the thermal energy in kcal released during the workout.

1) Suppose 500 mL of an 0.200 molar HCl acid is titrated with 70.0 mL of a 1.00 M NaOH solution. What is the final pH of the solution? The error interval is 0.1 pH units. 2) Suppose 500 mL of 0.100 M benzoic acid, which has a pKa of 4.201, solution is titrated with 75.0 mL of a 1.00 M NaOH. What is the final pH? The error interval is +/- 0.2 pH units.

). A 15 wt% Na2SO4 solution is fed at the rate of 12 kg/min into a miser that initially holds 100 kg of a 50-50 mixture (by weight) of Na2SO4 and water. The exit solution leaves at the rate of 10 kg/min. Assume uniform mixing, which means that the concentration of the exit solution is the same as the concentration in the mixer. (a) What is the total mass in the mixer at the end of 10 minutes? (b) What...

During the soybean experiment the nongerminating soybeans consumed around 0.02 mL/min of oxygen. What does this tell you about the cellular respiration of the nongerminating soybeans? Multiple Choice A) There was no cellular respiration. B) A little cellular respiration was taking place but not enough for growth. C)There was enough cellular respiration occurring to allow for growth. D) Photosynthesis was occurring instead of cellular respiration.

A 15% Na2SO4 solution is fed at a rate of 5.5 kg/min into a mixer which initially holds 45.5 kg of a 50-50 mixture of Na2SO4 and water. The exit solution leaves the mixer at a rate of 4.5 kg /min. Assuming uniform mixing, write the required mass balances and calculate the weight fraction of Na2SO4 in the mixer at the end of 10 min using 4th order Runge-Kutta Method by taking Δt= 0.5 min.
