There are 3 techniques learned in the lab to properly identify your product in organic chemistry. What are these 3 techniques? Explain in detail how each technique is used and what information you receive from using them?
2.00 moles of a gas occupies 62.2 L at a par- ticular temperature and pressure. Its density is 0.900 g/L. What is the molar mass?
Chlorine is widely used to purify municipal water supplies and to treat swimming pool waters. Suppose that the volume of a particular sample of Cl2 gas is 8.60 L at 899 torr and 28°C.
Calculate the final temperature when a 20.4 gram sample of ice at 0oC is placed into a styrofoam cup containing 111 grams of water at 72.7 oC. Assume that there is no loss or gain of heat from the surroundings.
What is the difference between the equatorial positions and the axial positions on the cyclohexane conformations?
A gas evolved during the fermentation of sugar was collected at 22.5°C and 702 mmHg. After purification its volume was found to be 25.0 L. How many moles of gas were collected?
The reaction 2NO (g)-> N2 (g) + O2 (g) has a H = 180.5 kJ. How much heat will be required to produce 44.8 L of NO by the reverse reaction?
Select the IR frequency and number of NMR signals that is diagnostic for either isomer a or isomer b. Isomer A: cyclopentanecarboxamide Isomer B: 6-hydroxyhexanenitrile
A 97 gram solution of silver nitrate contains 14 grams of AgNO3. What is the percent by mass of silver nitrate in this solution?
Determine the iodide ion concentration (in molarity) in a solution containing 12.6 g CaI2 dissolved in 2750 mL of solution
the pH of the solution is 9.15. After adding 16.55 mL of hydrochloric acid to your sample, the pH is 8.78. Calculate the first derivative of the function of the pH of your solution with respect to the volume of titrant added
