Methanol at 675°c and 1 bar is fed at a rate of 100 mol/s is fed to an adiabatic reactor where 25% of it is dehydrogenated to formaldehyde according to the reaction chaoh (g) hcho (g) +h2 (8). calculate the temperature of the gases leaving the reactor assuming that constant heat capacities of 17, 12, and 7 cal/mol°c for ch3oh, hcho, and h2, respectively are applicable. heat of formation for hcho (g) and ch3oh (g) are-27.7 and 48.08 kcal/mol

Infants born with severe respiratory problems are sometimes given liquid ventilation: they breathe a liquid that can dissolve more oxygen than air can hold. one of these liquids is a fluorinated compound, cf3(cf2)7br. the solubility of oxygen in this liquid is 66 mlo2 per 100 ml liquid. in contrast, air is 21 % oxygen by volume. calculate the moles of o2 present in an infant's lungs (volume: 12 ml ) if the infant takes a full breath of air. assume a pressure of 1 atm in the lungs.

In which of these cases are the two wave points considered to be in phase with each other?

Although respiratory organs vary across different organisms, they all contain respiratory surfaces that have a large surface area and are extremely thin. explain why having an extremely thin respiratory surface with a large surface area is advantageous for the process of gas exchange
