An unknown particle is caused to move between two electrically charged plates, as illustrated in Figure 2.8. Its path is deflected by a smaller magnitude in the opposite direction from that of a beta particle. What can you conclude about the charge and mass of this unknown particle?
Problem- If 10.95 mL of a standard 0.1080 M KOH solution reacts with 58.85 mL of CH3COOH solution, what is the molarity of the acid solution
A sample of atomic hydrogen (not diatomic, ignore fine structure) contains slightly more than 1 mole of atoms such that exactly 1 mole of them are in the ground state. At what temperature should we expect to find exactly 1 atom in the n = 3 state?
If the mole fraction of the ethanol in the solution is 0.65, calculate its mole fraction in the vapor phase at this tempature.The vapor pressures of ethanol and 1-propanol are 108mmhg and 40 mmg respectively.
A sample of an ideal gas at 1.00 atm and a volume of 1.89 L was placed in a weighted balloon and dropped into the ocean. As the sample descended, the water pressure compressed the balloon and reduced its volume.
a ground state h-atom absorbs a photon of wavelength 84.10 nm andits electron attains a higher energy level. the atom
When power was turned off to a 30.0 gal. water heater, the temperature of the water dropped from 75.0°C to 22.5°C. How much heat was lost to the surroundings? (1 gal = 3.785 L) Assume the density of water is 1.00 g/mL.
When you measure a volume of a liquid using a graduated cylinder, read the top position of the meniscus of a liquid to determine the volume 2.Extra chemicals you sampled should be returned into the original container
Compute the total change in Enthalpy (delta H) if you heat 25 grams of mercury liquid from 25 degrees Celsius to 75 degrees Celsius as well as also increase the pressure from 1 bar to 75 kbar
If a gas expands against a constant external pressure of 0.9 bar until its volume has amplified from 2.2 L to 6.2 L. During this process it absorbs 760.0 J of heat from the surroundings. Compute the energy change of the gas.
Calculate the molarity of a solution made by dissolving 5.00 g of glucose (C6H12O6) in sufficient water to form exactly 100 mL of solution.
Question- KI has a face-centered cubic unit cell in which the I- anions occupy corners and face centers, while the cations fit into the hole between adjacent anions. What is its density if the ionic radii of K+, I- ions are 169.1 pm and 184.0 pm, ..
sing two 2-bit comparator modules and some extra gates, design a 5-bit comparator comparing X = (X4X3X2X1X0) and Y = (y4y3y2y1y0). Show your design by drawing the logic diagram containing all three outputs, f(X>Y), f(X = Y), and f(X
