Write the cell notation for a voltaic cell with the following half-reactions Al(s) ? Al3+(aq) + 3e- 2H+(aq) + 2e- ? H2(g)
Find the Qsp if The solubility product of Ag 2 CO 3 =6.2 × 10-12. Also determine whether a precipitate forms in the solution (Assume 20 dropsper milliliter.)
What is the mechanism for turning 1-bromotbutane when it reacts with KI and DMF into n-butyl acetate?
Given the following reaction: 4 KO2 + 2 H2O + 4 CO2 ==> 4 KHCO3 + 3 O2 How many moles of O2 will be produced if 3.12 moles of CO2 react completely?
For a reaction in which delta H= -360.1 kJ/mol and delta= - 90.0 J/K*mol, determine the temperature (in *C) below which the reaction is spontaneous.
How is temperature correlated with the relative rates of this reaction. What is your explanation of this correlation
Calculate the temperature of boiling water at an elevation of 6000ft (2000m) given that the atmospheric pressure is 0.8atm. Assume delta H_vap is independent of T.
Assuming that the peaks are Gaussian, calculate the % resolution, i.e. calculate the area under the first peak which lies to the left of half way between the two peaks.
Conductivities are often measured by comparing the resistance of a cell filled with the sample to its resistance when filled with some standard solution, such as aqueous potassium chloride. The conductivity of water is 76 mS m^?1 at 25°C
Calculate the equilibrium concentration of Ag+ under these conditions.Ksp for Ag2CO3 is 8.1 x 10-12. Ag2CO3(s, excess)2Ag+(aq) + CO3-2(aq)
A container id filled with 4 moles of water and the molar mass of water is 18 grams per mole. What is the mass of the water in the container in grams
Imidazole is a weak acid, and thus reacts with strong bases to form the corresponding anion. Show this reaction, and draw resonance structures that account for the stability of conjugate base.
