Clearly Label the IR Spectrum of Benzoic Acid and assign the following peaks: Broad 3300-2500cm-1 3020 cm-1 1682cm-1 2. Clearly Label the IR Spectrum of Anisaldehyde and assign
A gas sample containing 1.64 mol at 25°C exerts a pressure of 389 torr. Some gas is added to the same container, and the temperature is increased to 50.°C.
Calculate the cell potential after the reaction has operated long enough for the [Al3+] to have changed by 0.32 mol/L. (Assume T = 25°C.)
Four liters of water are equilibrated with a gas mixture containing carbon dioxide at a partial pressure of .3 atm. Henry's law constant for H2CO3* solubility is 2.0 g/L-atm.
Do not forget to first determine the Ka, setup an "ICE" table, define the equilibrium concentrations of the finally and the significantly present at equilibrium.
Draw one planar structure each for the following compounds using dashed or solid wedges to show the stereochemistry of the substituent groups. To be graded properly, include the hydrogen atoms on the chirality centers (asymmetric carbons).
Calculate OH- for each of the following solutions, and indicate whether the solution is acidic, basic, or neutral. h+ = 2.7×10?3.
In C7H8BrNO there are 4 degrees of saturation. Will an open chain structure with 2 triple bonds exist? Open chain with 2 triple bonds. Is this incorrect. Is it too unstable to exist or is it possible.
Tank full of water (H2O)is open at the top with the hole near the bottom the area of which is 0.25 m^2 and the cross section area of the tank =1 m^2 determine what is volumetric flow rate out of the hole.
