A student failed to standardize his NaOH solution with KHP. Instead, he calculated the NaOH solution concentration from the mass of NaOH his laboratory instructor dissolved to prepare the solution.
Would this result in an incorrectly high or low calculated mass percent of acetic acid in vinegar?

The bitter-tasting compound quinine is a component of tonic water and is used as a protection against malaria. It contains only C, H, N and O. When a sample of mass 0.487 g was burned, 1.321 g of carbon dioxide, 0.325 g of water, and 0.0421 g of n..
Assuming that the process is working as intended, draw and label the flowchart, do the degree-of-freedom analysis, and estimate the molar flow rate (lb-mole/h) of the humidified outlet air.
Why are some covalent bonds polar and others aren't? Understand why the covalent bonds of water are polar and those in the hydrogen molecule (H2) are non-polar.
