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
1.25 L container holds a stoichiometric mixture* of ethene (CaH4), ethane (CaH6) and oxygen at a total pressure of 1.55 atm and a temperature of 24.5 °C. The mixture is ignited and completely combusts to form carbon dioxide and water. The water is removed from the vessel, leaving only carbon dioxide at a total pressure of 0.926 am at the same conditions. What is the mole fraction of oxygen in the original mixture?
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…
Nitroglycerin is a dangerous powerful explosive that violently decomposes when it is shaken or dropped. The Swedish chemist Alfred Nobel (1833-1896) founded the Nobel Prizes with a fortune he made by inventing dynamite, a mixture of nitroglycerin and inert ingredients that was safe to handle. 1. Write a balanced chemical equation, including physical state symbols, for the decomposition of liquid nitroglycerin (C₂H5(NO3)₂) dioxygen, gaseous water and gaseous carbon dioxide. into gaseous dinitrogen, gaseous 2. Suppose 13.0 L of carbon dioxide gas are produced by this reaction, at a temperature of -11.0 °C and pressure of exactly 1 atm. Calculate the mass of nitroglycerin that must have reacted.

A mixture of gases consists of 0.4 kg of oxygen, 0.7 kg of carbon dioxide, and 0.2 kg of helium. This mixture is maintained at 100 kPa and 27 °C. Determine the apparent molecular weight of this mixture the volume it occupies, the partial volume of the oxygen, and the partial pressure of the helium. (
Determine the partial molar volume of a component of a gas mixture based on the provided equation of state. When PV (1 – bP) = n2RT, the constant b is taken into consideration.
Insects do not have lungs as we do, nor do they breathe through their mouths. Instead, they have a system of tiny tubes, called tracheae, through which oxygen diffuses into their bodies. The tracheae begin at the surface of the insect's body and penetrate into the interior. Suppose that a tracheae is 1.34 mm long with a cross-sectional area of 2.46 x 10-9m2. The concentration of oxygen in the air outside the insect is 0.794 kg/m3, and the diffusion constant is 1.26 x 10-5 m2/s. If the mass per second of oxygen is diffusing through a trachea is 1.66 x 10-12 kg/s, then find the oxygen concentration at the interior end of the tube.

The mole fraction of He in a He/Ne mixture at 300 K is 0.40. If the total pressure is 1.2 atm, determine the value of ZNe-He. Use rHe = 0.13 nm, rNe = 0.14 nm, MHe = 4 amu, and MNe = 20.18 amu. Use units of the International System. Use up to a maximum of 3 significant figures in the answer, DO NOT include units. Use the following notation: 6.02e23 if your answer is 6.02 x 1023 or 6.63e-34 if your answer is 6.63 x 10−34. Note that there are NO spaces between any digits of the answer.

b) Connecting a physical protocol to quantitative expressions: In medical treatments, you often never work with pure oxygen. [In fact, breathing high concentrations of oxygen is toxic and can lead to hyperoxia]. Suppose you would like to prepare a mixture of nitrogen and oxygen gases. You have a 1.0-L flask of N₂(g) stored at 2.1 bar and T = 50.°C and a 2.0-L flask of O₂ (g) stored at 1.0 bar and T = 20.°C. Assuming ideal gas behavior, what is the final pressure (in bars) if you combine the two flasks into a 5.0-L flask at room temperature?
