Determine the molar ratio of NaBH4 to benzophenone that you ACTUALLY used in the experiment. why do you think that it was necessary to use a greater molar ratio than the equations at the beginning indicate?
Determine the balanced net ionic equation when aqueous solutions of AgNO3 and NaI are mixed. The balanced net ionic equation is:
The stopcock connecting a 2.25 L bulb containing oxygen gas at a pressure of 4.00 atm, and a 5.25 L bulb containing neon gas at a pressure of 8.00 atm, is opened and the gases are allowed to mix.
While cytotoxicity, antiviral activity, and immunosuppressant properties of didemnin-C and of its 8 analogs were excellent to very good, these compounds were, unfortunately, dropped from further studies and development at the stage of human trials..
what is the vapor pressure at 40 degrees Celcius of a solution containing 4.60*10^2 g of glycerin, C3H8O3, nonvolatile, nonelectrolyte solute, in 4.5*10^2 g of water? The vapor pressure of water at 40 degrees Celcius is 55.3 mmHg
What is the pH at the half-stoichiometric point (that is, what is the pH when you have added 50% of the total volume of base required to react with all of the acid originally present?)
Calculate the heat evolved from a mixture of 14.6 L of sulfur dioxide at 1 atm and 294 K and 15 g of oxygen if the following reaction occurs: 2 SO2(g) + O2(g) ?? 2 SO3(g) ?H? = ?198 kJ
We could find out more information about ths reaction by studying the temperature dependence of the rate constant, k. These same experiments could be carried out at a lower temperature (ice bath) and a second rate constant, k2 could be determined ..
1.27 (singlet, 6H); 2.12 (triplet,2H) and 4.26 (triplet, 2H). Determine the structure of the product and draw complete mechanism to show how it is formed.
Draw the structure of the unbranched isomer of C5H11Br that is most reactive in an SN2 reaction.
Calculate the specific heat capacity of this sample of mercury if The amount of energy required to heat 2.00 grams Hg from 50 degrees C to 85 degrees C is 9.87 J.
The solubility product for Pb3(PO4)2 is 1.0 x 10^-54. write out the solubility reaction equation explaining why it is set up that way using the solubility rules or else I will not really understand how to set up the problem.
