Students were instructed to mix the benzaldehyde and acetone starting materials in their conical vials before adding the ethanolic sodium hydroxide solution. a. Why was this essential to the success of the reaction? b. What would have been the most likely product formed if the sodium hydroxide solution were added to the vial first, followed by acetone and then waiting a few minutes to add the benzaldehyde? c. Provide a balanced equation
Calculate the pre-equilibrium concentration of Fe3+(aq) in a solution made by mixing 2.8 mL of 2.010?3 M Fe(NO3)3 and 7.2 mL of 2.010?3 M NaSCN. Assume the final volume is 10.0 mL.
Consider the boron trifluoride molecule, BF3, that results from the bonding of three fluorine atoms and one hybridized boron atom. A) The nub that is seen just below the boron central atom is one of the ends of a hybrid sp2 orbital.
Standard solutions of calcium ion are suually prepared by weighing an apporpriate amount of primary standard grade calcium carbonate, dissolving it in concentrated HCl, and diluting to the appropriate volume.
Calculate the expected theoretical yield of aspirin based on exactly 1 g of salicylic acid and 3.50 mL of acetic anhydride (density = 1.082 g mL-1).
A 33.0-g sample of an alloy at 93.0°C is placed into 258 g of water at 22.0°C in an insulated coffee cup. Assume that no heat is absorbed by the cup. If the final temperature of the system is 31.1°C
A study of this system reveals that there are 4.0E-3 moles of sulfur dioxide gas, and 4.9E-3 moles of oxygen gas present in a 9.0L flask at equilibrium. The equilibrium constant for this reaction is 4.1E-3. Calculate the number of moles of SO3(g) ..
Calculate the pH at the points in the titration of 40.00 mL of 0.425 M NH3 for the reaction below. NH3(aq) + HNO3 NH4+(aq) + NO3?(aq) For NH3, Kb = 1.8x10-5.
Microwave ovens use microwave radiation to heat food. The microwaves are absorbed by moisture in the food, which is transferred to other components of the food. As the water becomes hotter
A 1.80 g sample of a large boimolecule was dissolved in 18.0 g of carbon tetrachloride. The boiling point of this solution was determined to be 77.85°C. Calculate the molar mass of the biomolecule.
small protein in 5.00mL aqueous solution has an osmotic pressure of 7.85 torr at 23.1C. What is the molar mass of the protein?
Alfred bought a new graduated cylinder for his chemistry class. It holds 416 milliliters of liquid. If the cylinder has a radius of 4 cm, then how tall is the cylinder?
