a) Show the full balanced equation of Benzaldehyde + Sodium Cyanide -> Benzoin. Stoichiometry ratio should be 2:1. Ratio of -CN to benzoic is 1:1 if that even helps. Rely on Sodium Cyanide being 0.54M in 95% Ethanol. b) Use the density of benzaldehyde to calculate its mass. 400 microliters were used in my experiment, and the MW is 106.13. C) Thus, Find the Limiting Reagent, Theoretical yield, and % Yield of Benzoin. Obtained yield in experiment was .0246g benzoin crystals, and again, 400microliters of benzaldehyde used AND 4mL of Sodium Cyanide (0.54M in95% ethanol) was used. PLEASE SHOW NICE LEGIBLE WORK SO I CAN UNDERSTAND WHAT IS GOING ON.

For triatomic molecules (i.e., molecules that contain three atoms) such as difluorine monoxide, F2O, there are only two possible molecular geometries, linear or bent.

a. Draw the Lewis structure for F2O (O is the central atom), and predict the molecular geometry using the VSEPR model.

b. Could infrared spectroscopy be used to confirm the molecular geometry that is predicted using the VSEPR model? That is, could the infrared spectrum for F2O be used to determine whether the molecule is linear or bent? Explain your reasoning.

How much energy, in kiloJoules, would be required to raise the temperature of 1.00 kilogram of liquid benzene (C₆H₆) from 20.0 dC to its boling point of 80.1dC and then to completely vaporize the benzene at this same temperature?
