Look carefully at the frontier MOs of the diatomic molecule, BF and determine the most basic site. Based on your observations, predict the structure that results when H+ adds to BF. For your answer, draw the product as a Lewis structure that satisfies the octet rule for both boron and fluorine.
An experiment requires 44.0 g of ethylene glycol, a liquid whose density is 1.114 g/mL. Rather than weigh the sample on a balance, a chemist chooses to dispense the liquid using a graduated cylinder. What volume of the liquid should he use?
Suppose that you are carrying out a dehydrohalogenation reaction on 2-bromo-2,3-dimethylpentane to yield alkenes
what will the concentration be after 3.00 minutes? B)A zero-order reaction has a constant rate of 3.40×10^?4 M/s . If after 80.0 seconds the concentration has dropped to 3.00×10^?2 M , what was the initial concentration?
normal glucose levels in the blood are from 70 to 10 mg glucose per 100 mL of blood. If the level falls too low, there can be brain damage.
A baseball pitcher's fastball is clocked at 100 miles per hour (mph). Calculate the wavelength of a 141 g baseball in nm at this speed.
Addition of HBr to 1-phenylpropene yield only (1-bromopropyl)benzene. Propose a mechanism for the reaction and explain using resonance structures why none of the other regioisomer is produced?
No desiccator is available. The sodium carbonate is cooled to room temperature, but the humidity in the room is high. how will this affect the reported molar concentration of the hydrochloric acid
A steel cylinder holds 150.0 mol argon gas at 25 degrees C and a pressure of 9.53Mpa. After some argon has been used, the pressure is 2.00Mpa at 19 degrees C. What mass of argon remains in the cylinder.
In a crazy situation the Oylan Vinegar Company has 10,000 gallons of vinegar with a concentration of .114 M. It also hass a .68% acetic acid by mass
The rate of a first-order reaction is followed by spectroscopy, monitoring the absorption of a colored reactant at 520 nm. The reaction occurs in a 1.48- cm sample cell, and the only colored species in the reaction has an extinction coefficient of..
One of the treatments for gangrene and the bends, is hyperbaric oxygenation. This occurs in a chamber in which oxygen is used at higher-than-normal pressures.
What is the theoretical yield when 0.040 g benzophenone is added to 1 mL methyl alcohol?
