Hydrogen gives off 120. J/g of energy when burned in oxygen, and methane gives off 50. J/g under the same circumstances. If a mixture of 5.0 g of hydrogen and 10. g of methane is burned, and the heat released is transferred to 50.0 g of water at 25.0C, what final temperature will be reached by the water?
Calculate the molarity of each of the following aqueous solutions. a. 5.0 ppb Hg in H2O b. 1.0 ppb CHCl3 in H2O c. 10.0 ppm As in H2O d. 0.10 ppm DDT (C14H9Cl5) in H2O.
Suppose a 125-lb person lies supine on a board resting on knife edges spaced 72 in. apart (Fig. 5.7). Assume that the center of gravity of the lower limb is located through the center line of the limb and 1.5 in. above the knee cap. Estimate the w..
Two compartments, with equal volumes of 0:0572 cm3, are separated by a thin membrane. If all of the solute is initially dumped into one compartment, then find the transfer rate if the time constant equals 27 103 s.
The force plate in Figure 4.9 is 70 cm by 70 cm square. At a particular instant of the gait cycle each transducer reads F1 ¼ 210 N, F2 ¼ 220 N, F3 ¼ 150 N, and F4 ¼ 180 N. Compute the resultant force and its location.
A 25 wt% solution of coffee in water at 70°F is spray dried to a final moisture content of 5% (dry basis) with air that enters at 450°F and 1 atm with a humidity of 0.01 lb/lb (dry basis) and exits at 200°F. Assuming a reasonable value for the spe..
The resting potential of the membrane is 52 mV at room temperature. Find the Kþ cytoplasm concentration.
The reflux ratio is set at 4.0:1. Calculate the kg mol/h distillate D and bottoms W and their compositions. Also, calculate the number of theoretical plates required.
Plain carbon steel would be a suitable material for the tanks, but it is essential that the polymer does not become contaminated with iron in storage. Suggest some alternative materials of construction for the tanks.
For parts (a), (c), (d), (f), and (h) of Problem 10.20, determine the approximate percentages of the microconstituents that form. (a) Rapidly cool to 250(C (480(F), hold for 103 s, then quench to room temperature.
For honey, which is Newtonian, the plot should be linear with the slope equal to the viscosity. Calculate the viscosity (or let Excel do it for you). Do a little Google or literature searching and see if you can find a value for the viscosity of h..
Calculate the average mechanical torque needed to turn the coil and generate power for the resistor. Identify the action of the device as that of a motor or a generator.
Find the rated and maximum torques.
