Suppose the Union Station in Chicago (a large train station) contains, on average, 20,000 people. Assume trains and people come in and out at a steady rate, without special correlation. What is the range width of the actual number of people present at the Station at any given moment? (For concreteness, assume the fluctuations do not exceed one sigma)
The carburizing gas holds the surface composition at 1% carbon for all t > 0. If D=1.4 x 10^-7 cm^2/sec: (a) Calculate the time required at the carburizing temperature
Calculate the pH of a solution made by adding 77 g of sodium acetate, NaCH3COO, to 24 g of acetic acid, CH3COOH, and dissolving in water to make 700. mL of solution.
The tire is filled with dry air at sea level and a temperature of 60 degree F to 32 lb/square inch.standard sea level pressure is 101325 Pa at 0 degree C (STP).
Cd2+, Co2+ is saturated with H2S at a pH of 3.00. Which metals form a sulfide solid? [H2S]sat=0.10 and Ka1= 1.3e-7 and Ka2=8.5e-14
consider an excited-state hydrogen atom. What is the energy of the electron in the n = 3 level? ground state energy
electrons having this speed would need to be treated as waves in atoms because the wavelength is on the order of the size of atoms.
An aqueous solution is 22.0% by mass ethanol, CH3CH2OH, and has a density of 0.966 g/mL. what is molality of ethanol
how much energy is required to vaporize 98.6 g of ethanol at its boiling point if its Hvap is 40.5 kj/ mol ?
draw and label structures cis and trans isomers of 3,4 -dibromo-3-hexene, 3) structure of terpin hydrate. Is it more water soluable or less than the starting material?
This equation means that no matter how much carbon monoxide and oxygen gas is added to the flask, only 2 moles of CO and 1 mole of O2 will react to make two moles of Co2.
A mixture of CaCO3 and CaO weighing 0.630 g was heated to produce gaseous CO2. After heating, the remaining solid weighed 0.500 g.
when a 50.0-g nugget of pure gold is heated from 35.0 C to 50.o C, it absorbed 5200.0J of energy. find the specific heat of gold.
