How are you suppose to remember all the rules for these compounds? And how will you know when to apply them in a certain problem?
ideal gas originally at STP expands irreversibly and isothermally from point A to point B in the Carnot cycle diagram. It then is expanded reversibly and adiabatically from B to C.
Barium metal crystallizes in a body centered cubic lattice. the unit cell edge length is 502 pm and the density of the metal is 3.50g/cm3. using the information, calculate the avogadros number. assume 68% of the unit cell is occupied.
Do the same to show the formation of both elimination products from 2-bromo-2methylbutane (page 208 lists the two products as 2-methyl-1-butene and 2-methyl-2-butene.)
Write out a detailed mechanism for the formation of dibenzalacetone, using acetone + benzaldehyde in NaOH.
This increases to 0.010 Msec^-1 at 90 degrees C. Calculate the activation energy for this reaction.
Calculate the density in kg/m3 using (a) the ideal gas equation of state and (b) the compressibility factor equation of state in conjunction with the law of corresponding states.
A student is asked to prepare a buffer solution at pH=8.60 using one of the following weak acids HA (kA=2.7*10^-3), HB (Ka = 4.4*10^-6) and HC (Ka = 2.6 *10^-9).
Why do you think we need to convert the calcium carbonate to calcium chloride befoe we do our EDTA titrations? What specific condition in our titrations require this?
The half-life of Chromium-51 is 28 days. Starting with an original sample size of 12.0 ?g, calculate the number of days it will take for the radioactive isotope
where its latent heat of vaporization is 20.4 kJ/mol. Its molar mass is 70.91 g/mol. (a) Calculate the internal energy change (deltaU) for vaporization of 100 g of Cl2(liq.)
Hexane has a density of 0.659 g/mL. How many milliliters would a student need to pour in order to get 49.5 g of hexane?
What would the pH at the half-equivalence point be for the first ionization of the triprotic acid phosphoric
