A gas consists of 83.0 mol% methane, 2.00 mol% ethane, and 15.0 mol% ethylene. A mass of 7.00 kilograms of this gas is to be compressed to a pressure of 200.0 bar at 90.0°C. Using Kay's rule, estimate the final volume of the gas. (m^3)
Titrations: Finding Mass Percent of Arsenic in a Pesticide, The arsenic in a 1.0211-g sample of a pesticide was converted to H3AsO4 by suitable treatment. The acid was then neutralized and exactly 40.00 mL of 0.05922M
Question- How much work must be done on a system to decrease its volume from 11.0 L to 4.0 L by exerting a constant pressure of 5.0 atm
If large quantities of chloroform an anesthetic, carbon tetrachloride (commonly utilized in the past for dry cleaning, and tetrachloroethene previously used as a degreasing agent were spilled in the environment
If the pressure of the ocean breaks the submarine forming a bubble with a pressure of 250 atm pushing on it, how big will that bubble be?
calculate the pH of a buffer solution made by adding 10.0g of anhydrous sodium acetate (NaC2H3O2) to 100 ml of 0.100M acetic acid. sume there is no change in volume on adding the salt to the acid.
A saturated solution of calcium hydroxide contains .38 grams of calcium hydroxide in each 250 mL of solution. What is the pH of the saturated calcium hydroxide?
Both borneol and isoborneol can be converted to camphor via Jones oxidation. Will both undergo the reaction at the same rate. Explain.
The following pairs of soluble solutions can be mixed. In some cases, this leads to the formation of an insoluble precipitate. Decide, in each case, whether or not an insoluble precipitate is formed.
Because HCl and NaOH are a strong acid and base respectively, they dissociate completely and the pH of the solution is dependent only on the excess acid or base in the beaker at that point in the titration.
