In the welding shop of the XYZ Manufacturing plant you have a cylinder with a volume of 548L of a compressed gas, and the pressure gauge shows 238 psig at the room temperature 25 C. A welder was instructed to go outdoors to weld, and the temperature in Texas at this time was 1300F. A welder had opened a valve to release gas at atmospheric pressure (P2= 760mmHg). Find Volume of a released gas at new conditions.
Calculate the specific heat capacity of the metal when the final temperature of the mixture =38.7?C.? (Assume that there is no energy lost to the surroundings.)
Calculate the molecular weight of the compound? Given that Kf=1.86 and the compound in not ionic.
This is a fact that Bromine(Br) is larger than chlorine(Cl) but indication of equilibrium constant suggests that a bromo substituent has a less preference for the equatorial position than chloro substituent? Explain it briefly?
The state function to describe a particle on a sphere is given as Ψ=2sin^2(?)+cos?(θ).calculate the expectation value of its angular momentum about the z-axis, energy and the square of the total angular momentum L^2.
How do you calculate the force of water hitting a concrete cylindrical pole. The velocity of the water is 2 ft/s, the depth of the water is 10 ft, and diameter of the pole is 3 ft. So what would be the total force exerted on the pole by the water?
