Each sketch below shows a flask with some gas and a pool of mercury in it. The gas is at a pressure of 2 atm. A J-shaped tube is connected to the bottom of the Task, and the mercury can freely flow in or out of this tube. (You can assume that there is so much more mercury in the pool than can fit into the tube that even if the J-tube is completely filled, the level of mercury in...
(a) Calculate the work done by the gas (in J) along the closed path shown below. The curved section between R and S is semicircular p (atm) 4.0 3.0 2.0 1.0 V (L) 1.0 2.0 3.04.05.0 (b) If the process is carried out in the opposite direction, what is the work done by the gas (in J)?
In gas absorption column experiment, the purpose of the experiment is to measure the absorption of carbon dioxide into water flowing down the tower, using the gas analysis equipment provided. The experiment procedure is as follows. 1. First fill the two globes of the absorption analysis equipment on the left of the panel with 1.0 Molar caustic soda. Adjust the level in the globes to the '0' mark on the sight tube, using drain valve Cv into a flask to...
Indicate whether the following experimental mistake will increase, decrease, or have no effect on the calculated value of R. A student completed the experiment without waiting for the test tube to cool after heating. Select ALL of the correct answers. a. All measurements should be made at the same temperature. b. The volume measured from the beaker will be high. c. The measured temperature is room temperature. d. The calculated value of Ris low. e. The calculated value of Ris...
1. In a counterflow heat exchanger, the heat loss to the environment is to be included in the mathematical model. Considering the case of the hot fluid on the outside and the colder fluid on the inside, as shown in Figure below, sketch qualitatively the change that the inclusion of this consideration will have on the temperature distribution in the heat exchanger. Also, give the energy equation taking this loss into account. Hot Cold Energy loss 2. Experiments are carried...

Describe your solutions in detail, because partial credit will be given based on your work. If additional information is necessary in solving the problems, DO use your engineering sense and provide reasonable assumptions and explanations. You may use your calculator if necessary. Use a language of your choice. Note: The following information may be used. Gas constant, R-8.314 J(mol K)-8.314 kPa L/(mol K)-0.082 L atm/(mol K)-6.132 lbr ft/(gmol K)=1,987 cal/(mol K). Atomic mass of N-14; Atomic mass of O= 1...
1. Procedure A. Lithium 2,6-dimethylphenoxide. In a 300-ml. flask, equipped with a magnetic stirrer and a reflux condenser and flushed with nitrogen, are placed 150 ml. of toluene (freshly distilled from sodium), 1.40 g. (0.202 mole) of lithium metal (Note 1) and 25.0 g. (0.205 mole) of resublimed 2,6-dimethylphenol. The mixture is heated under reflux with stirring for 36 hours; a nitrogen atmosphere is maintained for the reflux period (Note 2). The condenser is replaced by a distillation head with...
Ignore question [1], just need the problem description from it. [1] Water flowing in a pipe is determined to be moving at the velocities given in the diagram below. The higher level is 3 meters above the lower one and the pressure in the lower portion is measured to be 200 kPa. Determine the pressure inside the upper pipe Treat the water as an ideal fluid obeying Bernoulli's equation. Consider the path connecting poin in the lower pipe with point...
