Problem- The organic compound di-n-butyl phthalate, C16H22O4(l), is sometimes used as a low-density (1.046 g•mL-1) manometer fluid.
1) Compute the pressure (in torr) of a gas that supports a 631-mm column of di-n-butyl phthalate. The density of mercury is 13.53 g•mL-1.
I just need a general explanation of it please- Thanks!
Calculate the pH and the concentrations of all species present H3O+, F-, HF, Cl-, OH- in a solution that contains 0.10 M HF Ka = 3.5*10^-4 and 0.10 M HCl.
It would be greatly appreciated if someone can help me out with this question, explaining to me step by step how I can do this. What is the pH of a solution made by adding 8.80 grams of sodium acetate CH3COONa to 450 mL of 0.105 M hydrochloric acid
ATP is created from ADP and Pi in the mitochondria of most cells. this reaction is thermodynamically endergonic. what directly provides the energy for this reaction to occur
Calculate the minimum concentration of Cr3+ that must be added to 0.095 M NaF in order to initiate a precipitate of chromium (III) fluoride ( for CrF3, Ksp = 6.6 X 10^-11)
Compute the amount of isopentyl acetate that must be present in the reaction mixture at equilibrium, on the basis the quantities of starting materials used.
Calculate the molar concentration of each ion in the beaker. Assume that none of the ions react with any of the other ions, and the volumes are additive
Calculate the hydrogen ion concentration in a solution containing 7.89 g of strontium hydroxide in 600 mL of solution.
In a titration experiment to determine the Ksp of Calcium Hydroxide, we titrated our prepared Ca(OH)2 solution with a standard hydrochloric acid solution
Compare the energy cost in ATP equivalents of synthesizing separate from mitochondrial acetyl-CoA to the energy recovered by degrading separate to acetyl-CoA.
A sodium chloride crystal in a beaker. As water is added the salt dissolves into positive sodium ions and negative chloride ions. Hydration refers to the final state of this process such that the water molecules tend to orient around the ions.
The total precipitate was dissolved in HCl + HNO3. When the solution thus formed was treated with excess NaOH followed by H2O2, a colorless solution and a reddish brown precipitate were formed. The precipitate was found to be soluble in HCl, H2SO4..
Calculate the heat released as 115 grams of water cool from its normal boiling point (100 degrees C) to a temperature of 33 degrees C.
