Why are there axial and equatorial hydroxyl isomers for 4-tert-butycyclohexanol, but not for cyclohexanol?
calculate strain on Co-Cr rod. Assuming compression is elastic, calculate stress on rod. Then compare stress with given properties. Based on stress value, was the compression purely elastic?

Hydrazine (N2H4) and dinitrogen tetroxide ignite on contact to form nitrogen gas and water vapor. How many grams of nitrogen gas form when 1.00 X 102 grams of N2H4 and 2.00 X 102 grams of N2O4 are mixed
why is anhydrous sodium sulfate added to the organic solution remaining after the extractions with 6 M HCL and 6 M NaOH
What is the total concentration of ions in the solution obtained by mixing 0.50 L of 0.10M solution of barium chloride with 0.50 L of 0.20 M solution of sulfuric acid.
What volume of 1 M HCl do you have to add to change the pH of the solution to 6? Assume that the change in volume from adding HCl is negligible. Recall that pH = pKa + log([A-]/[HA]. I cannot, for the life of me, figure this out.
