Draw the skeletal structure of the major organic product given that excess NaOD is used and without an acid workup.
Draw products A through E for the following series of reactions. If both ortho and para product would form, continue on only with the para product, but mention that ortho would also be a product.
A stock solution of NaCl is made taking 150.2g in enough water to make 200.0ml. A 10.00 ml sample of this stock solution is diluted to 250.0 ml.
Each of four compounds shown has one signal in the aromatic region and one signal in the alkyl region of its H NMR spectrum. Use the integral values to determine which compound's H NMR spectrum is shown below
The total molarity of acid and conjugate base in this buffer is 0.100 M . A student adds 6.10 mL of a 0.380 M solution to the beaker. How much will the pH change?
Fluoride (F-) is toxic element (anion) that can be lethal at 0.20 g/70kg of body weight. But because F- at low levels (1ppm) aids in healthy teeth, municipal water sources normally add this level of fluoride.
a flask containing 352 ml of gaseous nitrogen is collected over water at a temperature of 22 degree Celsius. the total pressure of the gases was 742 mm Hg. how many grams of nitrogen were collected?
The endpoint in the titration is "overshot" A. is the reported molar concentration of the hydrochloric acid solution too high or too low. EXPLAIN
Explain would the calculated molarity of NaOH be too high or too low If the KHP weighed in your experiment today was contaminated with some unknown inert substance.
During the preparation of a solution, a solute is dissolved in a volume of solvent smaller than the desired volume of solution. Subsequently, solvent is added until the final volume of solution is reached
The concentration of the primary waste in the pond is 35 mg/L. All of a sudden, the process changes and the concentration of the waste in the stream coming into the pond jumps to 250 mg/L. The pond is 500,000 L and the flow rate of the waste comin..
A sample of nitrogen gas is contained in a piston with a freely moving cylinder. At 0 C, the volume of the gas is 307 mL. To what temperature must the gas be heated
What is the concentration of dissolved O2 in blood (or water) at this partial pressure and a normal body temperature of 37C? The solubility of O2 in water at 37C and 1atm partial pressure is 1.93x10^-3 mol/L?
