Low molecular weight ketones are soluble in water. Explain what is the shortest length of the carbon chain where insolubility becomes important?
the two reactions involved in quantitatively determining the amount of iodate in solution areio3-aq 5 i-aq 6 haq --gt
Chemists studied the formation of phosgene by sealing 0.81 atm of carbon monoxide and 1.37 atm of chlorine in a reactor at a certain temperature. The pressure dropped smoothly to 1.55 atm as the system reached equilbrium. Calculate Kp (in atm-1) f..
Calculate the wavelength (in nanometers) of a photon emitted by a hydrogen atom when its electron drops from the n = 5 state to the n = 3 state
The rate would decrease because the bromide ion is a weaker base than the iodide ion. C) The potential change cannot be predicted.
explain why it is dangerous to mix solutions in a test tube by placing a finger
Diethyl ether is a volatile organic compound. The vapor pressure of diethyl ether is 401 mm Hg at 18°C and the Hvap = 26.0 kJ/mol. Calculate the vapor pressure of diethyl ether at 40°C.
Consider a solution formed by mixing 51.0 mL of 0.100 M H2SO4, 27.0 mL of 0.100 M HOCl, 25.0 mL of 0.200 M NaOH, 25.0 mL of 0.100 M Ca(OH)2, and 10.0 mL of 0.150 M KOH. Calculate the pH of this solution.
Estimate the temperature above which this reaction is spontaneous. DS0 = 16.1 J/K. CH4(g) + N2(g) + 163.8 kJ ® HCN(g) + NH3(g)
The solution has a density of 1.286 g/cm^3. Calculate E for the cell. Assume all the H+ ions come from the first dissociation of H2SO4 which is complete
If a contemporary wooden chair were somehow preserved to for the next 3,900 years, what C-14 dacay rate should be expected from the wood used to make the chair? (t1/2 = 5730)
a sample of water of 27.0 grams at the temperature of 290. kelvin is combined with 49.0 grams of water at 32 degree
Which properties are the same for both reactions and which are different? the number of atoms of each element, the state of the methane molecules, the enthalpy change of the reaction, the state of the carbon atoms.
