Consider Si uniformly doped with 1015 cm23 boron atoms.
(a) What are the carrier concentrations at 27°C?
(b) What are the carrier concentrations at 100°C?
(c) If 1 1016/cm3 2 phosphorous atoms are added, what are the approximate equilibrium electron and hole concentrations at 27°C?
Does the fact that two compounds have different boiling points mean that they definitely can be separated by gas chromatography
a certain first-order reactio has a rate constant of 3.60times10-3 at 45 . how many minutes does it take for the
A 12.4 g sample of CaCl2 is dissolved in 112 g of water, with both substances at 25.0°C. Calculate the final temperature of the solution assuming no heat lost to the surroundings and assuming the solution has a specific heat capacity of 4.18 J/°C·..
A quantity of CO gas occupies a volume of 0.64L at 1.0atm and 323K. The pressure of the gas is lowered and its temperature is raised until its volume is 4.6L. Find the density of CO under the new condition
Place the subsequent molecules and ions in order of increasing bond angle about the central atom as well as explain your decision citing evidence from Part B.
A solution is prepared by disolving 0.60 g of nicotine (a nonelectrolyte) in water to make 12 ml of solution. The osmotic pressure of the solution is 7.55 atm at 25 celcius. The molecular weight of nicotine is HOW MANY g/mol
Starting with only the solid, it is found that at 40C the total gas pressure (NH3 and CO2) is 0.33 atm. Calculate the euilibrium constant Kp/
Nonmetals like C,N,S and P are typically the central atom in a molecular compound rather than nonmetals such as O,F,H and Cl. One reason for this is
the equilibrium constant kc for the reactionpcl3g cl2g pcl5gnbspis 49 at 230degc. if 0.70 mol of pcl3 is added to 0.70
A galvanic (voltaic) cell consists of an electrode composed of chromium in a 1.0M Chromium(II) ion solution and another electrode composed of silver in a 1.0M silver ion solution, connected by a salt bridge.
commercially available styrene contains about 15 ppm of 4-tert-butylcatechol. Draw the structural formula for 4-tert-butylcatechol
Consider the decomposition of N2O5 in carbon tetrachloride (CCl4) at 45?C 2N2O5(soln) 4NO2(g) + O2(g) The reaction is first-order in N2O5, with the specific rate constant 6.08 x 10-4/s. Calculate the reaction rate at these conditions.
