A tube is bent at 90 degree. The horizontal end of length L is closed but the vertical end is open to the atmosphere. A fluid of density (p) fills the tube to a height H and the tube is rotated about the vertical axis at rotational speed w. Find the gage pressure at the closedend as function of at most p, g, w, L and H.
What is the ionization state of aniline (protonated, deprotonated, or a mix) at pH 1, 4.6, and 14?
This mixture has density of 1.391g/L and occupies a volume four times as that of pure hydrocarbon. Determine the molecular formula of the hydrocarbon.
Describe how you would prepare each of the following aqueous solutions. - 230 g of a solution that is 0.60 molal in Na2CO3 starting with the solid solute.

A 59.0-g sample of an alloy at 93.0°C is placed into 264 g of water at 22.0°C in an insulated coffee cup. Assume that no heat is absorbed by the cup.
Calculate kp and kc for the dissociation.
Orange juice is an aqueous solution that derives much of it's acidity from citric acid. There are variations in the acidity of each brand depending on many factors
When most Fe^3+ salts are dissolved in dilute nitric acid, the solution is often yellow to orange-yellow in color. Why could you not visually detect these colors in Fe(NO3)3 stock solution
Calculate the percent by mass of calcium carbonate in the rock, assuming that it is the only substance reacting with the HCl solution.
Four materials (A, B, C, D) have approximately equal melting points. All possible combinations of two of the four solids were prepared by combining equal amounts of each solid.
For your unknown titration, indicate whether the pH at the equivalence point should be equal to 7.0, greater than 7.0, or less than 7.0. Explain your choice, including the appropriate balanced net ionic equation.
