- CPAP is the acronym for "Continuous Positive Airway Pressure". A CPAP device is used in respiratory therapy. Some ambulances carry a CPAP device. The pressure unit used in CPAP devices is "cm H2O". A typical pressure setting on a CPAP device may be 9 cm H2O. Blood pressure is commonly measured in units of mm Hg (or millimeters mercury). Which of the following statements is true regarding the pressure of 1 cm H2O ? Question 17 options: A) 1 in H2O has a lesser pressure than 1 cm H2O. B) 1 in H2O has a greater pressure than 1 cm H2O. C) 1 mm Hg has a lesser pressure than 1 cm H2O. D) None of the above answer choices are correct.arrow_forwardSome commercial drain cleaners contain two components; sodium hydroxide and aluminum powder.

- 62 Ammonium dinitramide (ADN), NH4N(NO2)2, was considered as a possible replacement for aluminium chloride as the oxidizer in the solid fuel booster rockets used to launch the space shuttle. When detonated by a spark, AND rapidly decomposes to produce a gaseous mixture of N2,O2, and H2O. (This is not a combustion reaction. The ADN is the only reactant.) The reaction releases a lot of heat, so the gases are initially formed at high temperature and pressure. The thrust of the rocket results mainly from the expansion of this gas mixture. Suppose a 2.3-kg sample of ADN is denoted and decomposes completely to give N2,O2, and H2O. If the resulting gas mixture expands until it reaches a temperature of 100°C and a pressure of 1.00 atm, what volume will it occupy? Is your answer consistent with the proposed use of ADN as a rocket fuel?arrow_forwardOne of the best-selling light, or low-calorie, beers is 4.2% alcohol by volume and a 12-oz serving contains 110 calories, to estimate the percentage of calories that comes from alcohol, consider the following questions.
