As electrons are added to the s and p sublevels in the same electron shell (level), they are pulled closer to the highly charged nucleus, causing what to happen?
Demonstrate how you could prepare each of the following compounds from Propane and any necessary organic or inorganic reagents.
what is the percent of magnesium in magnesium phosphate?
How many moles of H3O+ or OH - must you add per liter of HA solution to adjust its pH from 9.80 to 8.91? Assume negligible volume change.
Calculate delta rG^o for the reaction below at 25 degrees C. CS2(g) + 3Cl2(g) -> S2Cl2(g) + CCl4(g) given delta rH^o = -231.1 kJ/mol-rxn and delta rS^o = -287.6 J/K*mol-rxn
Restricting yourself to straight-chain (unbranched) compounds, draw the structures of the possible constitutional isomers of pentene. There are two "variables" -- the position of the double bond; and cis/trans isomerization at that double bond.
In a separate experiment, it was found that, for fixed temperature and pressure, a 0.100 L sample of this compound takes 1.73 times longer to effuse than does a 0.100 L sample of Ar(g). What is the molecular formula of the compound. draw possible ..
A system had 150 kJ of work done on it and its internal energy increased by 60 kJ. How much energy did the system gain or lose as heat?
If we have benzene, acetyl chloride, AlCl3 and HCl in a solution of NaoH and CH2Cl2 which of these will be in the NaOH layer and Which of them will be in the CH2Cl2 layer
A white solid remains in centrifuge tube after acetone extraction-it fizzes when hydrochloric acid is added suggesting sodium carbonate was formed- How did it form? Write a balanced equation for the formation?
Calculate the wavelength, in nanometers, of the spectral line produced when an electron in a hydrogen atom undergoes the transition from the energy level
Gold (Au) crystallizes in a cubic close-packed structure (the face-centered cubic unit cell) and has a density of 19.3 g/cm3. Calculate the atomic radius of gold in picometers.
A 0.4168-g sample of a compound known to contain only carbon, hydrogen, and oxygen was burned in oxygen to yield 0.7745 g of CO2 and 0.1586 g of H2O. What is the empirical formula of the compound?
