02-Sadra is a college student studying chemistry. In one of his labs, he needs to add 10 grams of sodium carbonate to a mixture and analyze the results. When he is measuring the chemical on a weight sensor, he notices the amount of Na2co3 he is weighing is much larger than everyone else's, yet the sensor reads 10 grams. He dumps the chemicals back into the container and reweighs it, only to get the same result. Which of the following is accurate in describing Sadra's weight sensor? Not reliable, and not valid O Not reliable, but valid O Reliable, but not valid Reliable and valid Question 10 02-Dr. Narayan conducted a research study about the effects that coffee has on the brain. However, he told participants that it was an on-going survey on the amount of coffee they consumed on a day-to-day basis. This type of study is known as deception.

4. True or False (1) Chlorine demand is the difference between total chlorine and free chlorine (2) In raw wastewater samples, most of nitrogen is in the form of nitrate. (3) If 10 mg/L of NH3-N is converted to nitrate, the nitrate concentration is 10 mg/L as N. (4) Free chlorine consists of hypochlorous acid and hypochlorite. (5) Chloramines is a weaker disinfectant than free chlorine. (6) Na2HPO4 contributes to the orthophosphates. (7) For phosphorus analysis, the purpose of the autoclave is to kill the phosphorus bacteria which interferes colorimetric analysis. (8) Chloride is an effective disinfectant for water and wastewater treatment. (9) "Crown" corrosion is caused by the corrosive action of H₂SO4. (10) Breakpoint chlorination can be used for removal of ammonia.

During a very light activity, such as reading or watching television, the average adult expends about 7 kJ/min. If you are going to read lectures for ENCHEM 1 for 3 hours, how many Calories (kcal) do you need? What should you eat prior to reading to have this energy? Take photos of the nutritional information of the food (if available) you are going to eat and verify whether the declared Calories (Kcal) are true by doing the fuel value estimation of the food. Or if you choose food with no nutritional information label like in the case of eating apple, you can take the picture of that apple then weigh the apple and refer to the data given in the Calorimetry lecture to perform fuel value estimation expressed in Calories unit. You can choose more than 1 food and you have to provide how many servings of this food you are going to eat.   Show your computation for the fuel value estimation of fod.

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

Be sure to answer all parts. Enter your answer in scientific notation. Carry out the following calculation, paying special attention to significant figures, rounding, and units (J-joule, the SI unit of energy; mol = mole, the SI unit for amount of substance): (6.022 x 1023 atoms/mol) (4.68 x 10-18 J/atom)(1-2-3-2)=[25.051 Note that the numbers 1 and 3 in the last term are exact. x 10 J/mol

Alexander, who weighs 180 lb , decides to climb Mt. Krumpett, which is 5860 m high. For his food supply, he decides to take nutrition bars. The label 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 contains 9 Calories, whereas each gram of protein and carbohydrates contains 4 Calories. Alexander wants to know exactly how many bars to pack in his backpack for the journey. To provide a margin of safety, he assumes that he will need as much energy for the return trip as for the uphill climb. How many bars should Alexander pack?
