Electrical energy is usually measured in kiloWatt-hours, kWh. A Watt is 1 joule per second. A kiloWatt is 1000 joules per second. An hour has 3600 seconds. Therefore 1 kWh = 3.6x106 joules. How many kWh are there in a meal that is 776 Cal, or nutritional calories? Just put in the number. The assumption is the unit is kWh. 1 Nutritional Cal = 1 kcal (exact) 1 cal = 4.184 joules (exact) kilo 103 (exact) 1 kWh = 3.6x106 joules (exact) =

A stock solution of analyte is made by dissolving 34.83 mg of copper (II) acetate hexahydrate(fw = 289.73 g/mol) in 25.00 mL of water. A second stock solution of internal standard is madeby dissolving 28.43 mg of germanium (I) acetate (fw = 190.74 g/mol) into 25.00 mL of water.These solutions are used to make a series of standards for flame atomic absorption analysiscalibration. The standard solutions (each 10.00 mL total volume) should have the followingconcentrations of copper: 10.00; 25.00; 50.00; 100.0; and 200.0 μM. Each calibration solutionshould also contain 50.00 μM of germanium. What is the analyte stock solution concentration? What is the internal standard stocksolution concentration?Complete this table.

O Macmillan Learning One important test for kidney disease involves measuring the levels of bicarbonate (HCO,) in blood. Normal bicarbonate levels for a person ranging in age from 18 to 59 years old is 23-29 mmol/L. A lab purchased a new instrument to measure bicarbonate levels in blood and needs to certify it against their current instrument. The bicarbonate levels in the blood of a 38 year old woman was measured using the old and new instrument. The blood was tested 6 times using each instrument. The mean concentration of bicarbonate using the old instrument was found to be 24.4 mmol/L. with a standard deviation of 1.54 mmol/L. The new instrument yielded a mean concentration of 25.5 mmol/L with a standard deviation of 0.48 mmol/L... Determine if there is a significant difference in the standard deviations of the two sets of measurements made by the two instruments at the 95% confidence level. Determine the value of Fale Feale= 10.293 Determine the value of Fuble- Refer to the table…
