what is the densest material known at ordinary pressures (1 atm)?
The lowest pressures readily attainable in the laboratory are of the order of 10^(-13) atm. At this pressure and ordinary temperature (say T=350K), how many molecules are present in a volume of 1cm^3
At a certain temperature and total pressure of 1.2 atm. the partial pressures of an equilibrium mixture for 2A(g) B(g) are P_A - 0.60 atm and P_B - 0.60 aim. After a disturbance, the system regains equilibrium with a total pressure of 1.6 atm. What is the partial pressure of A at the equilibrium ? atm
Convert the given pressures from the units of torr or mmHg into atm. Enter a numerical value with three significant figures. Remember, leading zeros are NOT counted as significant figures. 1) 856 torr = atm 2) 156 mmHg = atm
Calculate ΔG at 298 K if the partial pressures of NO2 and N2O4 are 0.40 atm and 1.64 atm , respectively. please explain. thanks in advance
18) Calculate the pressure of N2 if the equilibrium pressures of H2 = 2.0 atm, and NH3 = 0.5 atm, and Kp = 2.0 N2(g) + 3 H2(g) = 2 NH3(g) A) 0.031 atm (B).016 atm C) 0.062 atm D) 62,5 atm E) 0.40 atm 19) Consider the following reaction: CH4(g) + 2 H2S(g) = CS2(g) + 4 H2(g)
For the equilibrium 2PH3(g) ⇌ P2(g) +3H2(g), the equilibrium partial pressures are PPH3=0.049 atm, PP2=0.498 atm, and PH2=0.776 atm at 738K. Calculate Kp.
The Haber-Bosch process typically operates at ~700 K under pressures of ~200 atm and with a catalyst present. In 2-3 sentences, briefly explain what may be the reason for these conditions.
Pressurized gas systems usually have pressures greater than 1 atm. Give example of a pressurized gas system you have experience with. Explain the features of the system that allow the pressure to be released safely.
At very high pressures (M 1000 atm), the measured pressure exerted by real gases is greater than that predicted by the ideal gas equation. This is mainly because Multiple Choice such high pressures cannot be accurately measured. ces real gases will condense to form liquids at 1000 atm pressure. gas phase colisions prevent molecules from colliding with the walls of the container. of attractive intermolecular forces between gas molecules KPrev 6 of 10 Next> Multiple ChOice SUch high pressures cannot...
A gas cylinder can safely handle pressures up to 75.0 atm. If the gas pressure in the cylinder is 63.3 atm at 15 ◦C, what is the highest safe temperature for this cylinder? Assume ideal-gas behavior and V, n = constant. T(K) = T(◦C) + 273. (A) 17.8 ◦C (B) 68 ◦C (C) 243 ◦C (D) 291 ◦C (E) 341 ◦C
