A 7.50 -L container holds a mixture of two gases at 33 °C. The partial pressures of gas A and gas B, respectively, are 0.214 atm and 0.571 atm. If 0.220 mol of a third gas are added with no change in volume or temperature, what will the total pressure become?

The synthesis of methanol from carbon monoxide and hydrogen is carried out in a continuous vapor phase reactor at 5.00 atm absolute. The feed contains CO and H₂ in stoichiometric proportion and enters the reactor at 25 ^oC and 5 atm at a rate of 17.1 m³/h. The product stream emerges from the reactor at 127 ^oC. The rate of heat transfer from the reactor is 17.05 kW. Calculate the fractional conversion achieved and the volumetric flow rate (m³/h) of the product stream.

Consider the following reaction:

CO2(g)+CCl4(g)⇌2COCl2(g)

Calculate ΔG for this reaction at25 ∘C under these conditions:

PCO2= 0.140 atm

PCCl4 = 0.170 atm

PCOCl2= o.740 atm

ΔG∘f for CO2(g) is −394.4kJ/mol, ΔG∘f for CCl4(g) is −62.3kJ/mol, and ΔG∘f for COCl2(g) is −204.9kJ/mol.

Express the energy change in kilojoules per mole to one decimal place.

Newton’s laws of motion, such as trajectory and momentum, do not apply to subatomic particles as they do to larger objects such as baseballs. Research how subatomic particles (protons, neutrons, and electrons) behave and compare their behavior to the behavior of macroscopic particles that are governed by classical Newtonian physics.

·        How does the quantum, subatomic world differ from the world we can see and touch around us?

·        Specifically, do the same laws of classical physics for such things as momentum work in the subatomic world?

Which of the following is NOT a difference of archaeal membrane lipids relative to those of other organisms?

A backbone other than glycerol is used.

Fatty acid esters are replaced with long chain alcohol esters to the glycerol.

The long hydrophobic tails are branched rather than being linear.

Ether linkages instead of ester linkages are used.

Choose the most likely pattern for the crystal field diagram for the complex trans–[Ni(NH₃)₂(CN)₄]^2– where CN^– produces a much stronger crystal field than does NH₃.?

From the answer the pattern show it is a square planer. Could anyone explain it? why is not octahedral?
