The following table lists components in a gas fuel mixture stored in a 900 m³ tank at temperature 25°C and pressure 6400 kPa. MW, g/mol Methane, CH4 16 Propane, C3H8 44 What is the partial pressure (in kPa) of Propane? Mole Fraction 0.65 0.35

A gas at 110 kPa at 25.0°C fills a flexible container with an initial volume of 1.62 L. If the temperature is raised to 75.0°C and the pressure increases to 140Kpa, what is the new volume? How many liters of CO2 gas are created when is 150g of lactose is consumed? The conditions are: pressure of 1.54 atm, and the temperature is 41°C. The relationship between lactose and CO2 is:C12H22O11 + enzymes à 4 CO2+ many other byproducts

One type of gas mixture used in anesthesiologyis a 50%/50% mixture (by volume) of nitrous oxide (N2O) and oxygen(O2), which can be premixed and kept in a cylinder for later use.Because these two gases don’t react chemically at or below 2000 psi, attypical room temperatures they form a homogeneous single gas phase,which can be considered an ideal gas. If the temperature drops below-6C, however, N2O may begin to condense out of the gas phase. Thenany gas removed from the cylinder will initially be nearly pure O2; asthe cylinder empties, the proportion of O2 will decrease until the gascoming from the cylinder is nearly pure N2O. In another test, the valve of a 500 L cylinder full of the gas mixture at 2000 psi (gauge pressure) is opened wide so that the gas rushes out of the cylinder very rapidly. Why might some N2O condense during this process? (a) This is an isochoric process in which the pressure decreases, so the temperature also decreases. (b) Because of the rapid expansion, heat is…

Determine the volume (L) of hydrogen needed (based on room temperature 25 °C and l atm) to hydrotreat 1 liter crude oil with 1.8 wt % S to a sulfur content of 0.2 wt%. The oil has a specific gravity of 0.8 (compared to water). The stoichiometry follows the following reaction: Oil-S + 2H2¬→O¡I-H2 + H2S

How much carbon dioxide gas (mole percent) is dissolved in a bottle of sparkling water if the manufacturer used a pressure of 2.68 atm in the bottling process at 25°C?   HCO2inwater=1630atm and PsatH2O=3.166kPa at 25°C. Assume xH2O=1.
