Hypertension- Assignment 2

A lecture hall contains 12 rows of seats. If the professor releases laughing gas (N2O) from the front of the room and tear gas (C6H11OBr) simultaneously from the back of the room, in which row are the students apt to start and to cry simultaneously?

81. A 58-year-old man who is a construction worker comes to the office because of a 1-week history of pain on the right side of his head. One week ago, he says he struck his head on a beam while carrying drywall to the second floor of a house under construction. He has had dry mouth, excessive thirst, and increased urinary frequency during this period. His pulse is 120 /min, respirations are 25/min, and blood pressure is 120/65 mm Hg. Physical examination shows dry mouth and decreased skin turgor. Urine osmolality is 196 mOsmol/kg H₂O (N>287). An MRI of the brain shows a hyperintense sighal consistent with hemorrhage of the posterior pituitary gland. This patient most likely has decreased renal reabsorption of which of the following? OA) Chloride ions OB) Magnesium ions C) Potassium ions D) Sodium ions E) Water

1) ВНз, THF 2) NaOH, H2O2, H20

An action will release carbon tetrachloride to the atmosphere resulting in an air concentration at the source of 10° g/m3. Assume an adult inhales this contaminated air from 5pm to 9am on weekdays and 24 hours/day on weekends for their entire life, that it takes 5 minutes for the source to reach his window. Determine if the lifetime risk of developing a fatal form of cancer is acceptable.

You use a short period electrical stimuli to observe muscle fibers contracting continuously (tetanus).Chemical agents can cause tetanus by interfering with the motor neurons. These agents include atoxin produced by the soil bacterium Clostridium tetani. One of the symptoms of these agents iscalled 'spastic paralysis'! Explain in your own words why these agents would be a bad thing for youand your muscles.

Two standard scuba tanks are filled to 200 atm—the first with a volume of 14.2 L and the second with 11.4 L. Assume that the tank regulator delivers 1.5 L of air at 1 atm for each breath. How many breaths could each different tank supply if one used the contents of each tank completely?Hint: P1V1 = P2V2*Breaths Tank 1=? Tank 2=?     2.   Methane CH is a simple organic molecule that is used as a fuel—it is the major component of natural gas. The bottom of the ocean contains large amounts of methane hydrate (also called methane ice or methane clathrate), enough that it has been suggested as a major source of fuel. The methane hydrate contains 6 moles water for each mole of methane. What percentage of methane hydrate is methane?  What percentage is water?  3.  ______________ solids are made up of large numbers of independent, constituent units, some of which attract and others repel. 4.  ______________ solids have large numbers of covalent bonds, but not necessarily many component units.…

Alexander, who weighs 150lb, decides to climb Mt. Krumpett, which is 5250 m high. For his food supply, he decides to take nutrition bars. The labels on the bars states that each 100-g bar contains 10 g of fat, 40 g of protein, and 50 g of carbohydrates. One gram of fat contain 9 Calories, whereas each gram of protein and cabohydrates contain 4 Calories. Alexander wants to know excatly how many bars to pack for the journey. To provide a margin of safety, he assumes that he will need as much energy for the return trip as the uphill climb. How many bars should Alexander pack

Assume the average person needs 75mg of vitamin C per day. If you were to travelacross the Atlantic Ocean (a 50 day voyage), how much (in volume) of your commercialsample would be needed?

Please answer the following question:

-|· 4.0 H3C 3.0 Match the peaks in this spectrum with hydrogens on the structure below. A) I: 0.91 ppm II: 3.29 ppm III: 1.52 ppm IV: 3.23 ppm H₂ CH3 CH 2.0 CH3 IV ppm 1.0 B) I: 0.91 ppm II: 3.29 ppm III: 3.23 ppm IV: 1.52 ppm C) 1: 3.23 ppm II: 3.29 ppm

Calculate the amount of CO2 emitted in jordan from gasolene ( C8H17) powered vehicles Assume the compustion is complete in All CASES gasolene Densety =720gm/L we regard to jordanian consumption of 90 octane 95 octane gasoline jordanian consumed 1.908000000 Liter during 2019

If the atmospheric burden of CO2 increases by 27.0 Gt (gigatonnes, 1Gt= 1 x 1012kg) over a given period of time, starting now, and the current atmospheric CO2 is 408.3 ppm, what will the concentration of CO2 be (in ppm) after this increase? (Assume a total atmospheric mass of 5.10 x 1021 g and an average molar mass for air of 29.0 g/mol) 411.8 ppm 408.8 ppm 410.6 ppm 417.0 ppm

After Maria’s 8th cup of coffee one night during finals week, she remembered that high doses of caffeine can kill you. Maria was worried that she was more susceptible because she weighed only 47.7 kg. Maria did some research and found that 150 mg/kg of caffeine was lethal and the coffee she was drinking is 0.04% m/v caffeine. How many cups of coffee could Maria drink before she would likely die?

The average American woman self-reports consuming 1.785x10^3 kcal/day. For a 139.0lb woman, express this value in joules per second per kilogram of body mass (watts per kilogram).

If two aluminum cans of carbonated soft drinks, one “regular” made with sugar, (sucrose, C12H22O11) and the other diet, sweetened with Aspartame, are placed in a freezer, which one is more likely to explode? (remember that frozen water has a lower density than very cold liquid water)?= Explain your choice.

Before slow cooking a meat (for example, in a crockpot/slow-cooker) you will often find instructions to sear the meat on high heat in an oiled skillet for a few minutes before transferring it to the crockpot. The searing is brief – not long enough to cook the meat thoroughly. Despite myth/legend, the searing will not “seal in the juices”. What is the searing for?

Freediving is an activity in which a person dives, sometimes to great depth, without the use of scuba gear. The diver must hold his or her breath for the duration of the dive. The record depth, with no equipment such as diving fins, is 101 m; the official record time is over 11 minutes. Historically, freediving has been used by pearl divers and sponge divers. Some freedivers hyperventilate (breathe rapidly and deeply) before diving. Hyperventilation can change the concentration of CO2CO2 in the blood and may increase the length of time that a person feels like he or she can hold his or her breath. How does hyperventilation affect blood pH? - It increases CO2CO2 and H+H+ in the blood, decreasing pH. - It increases CO2CO2 and decreases H+H+ in the blood, decreasing pH. - It decreases CO2CO2 and H+H+ in the blood, increasing pH. - It decreases CO2CO2 and increases H+H+ in the blood, decreasing pH.
