Calculate the mass of oxygen (in mg) dissolved in a 5.00 L bucket of water exposed to a pressure of 1.13 atm of air. Assume the mole fraction of oxygen in air to be 0.21 and the Henry's law constant for oxygen in water at this temperature to be 1.3 × 10-3 M/atm.
What is the final volume of the balloon. Assume that the pressure inside and outside the balloon has the same value. Ans. V = 34.8 L
Hydroxyl radical (OH) is produced from the photolysis of H2O or through reaction with excited oxygen, H2O + hν --> H + OH or O* + H2O---> 2OH
The zinc within a copper-plated penny will dissolve in hydrochloric acid if the copper coating is filed down in several spots (so that the hydrochloric acid can get to the zinc).
A gas contains 17% O2, 11% CO2 and 72%N2. It is at 1.013 *105 Pa pressure. Calculate the partial pressure of each component
Why would a mixture of salts be more difficult to identify than a single salt? For example, copper sulfate, barium nitrate and nickel bromide versus only nickel bromide.
Can anyone please tell me what effect reacting a carbonyl compound, (specifically, (CH3)2CO) with LiCCH, followed by H2O
calculate the concentration in molarity of a NaOH solution if 25.0 ml of the solution are needed to neutralize 17.4 ml of a .312 M HCl solution.
The top stream contains diesel and heating oil. The middle stream contains heating oil and lubricating oil, and the bottom stream contains the solids
Formic acid, HCHO2, is a convenient source of small quantities of carbon monoxide. When warmed with sulfuric acid, formic acid decomposes to give CO gas
A sample of ammonia gas was allowed to come to equilibrium at 400 K.2NH3(g) ↔ N2(g) + 3H2(g) At equilibrium, it was found that the concentration of H2 was 0.0584 M, the concentration of N2 was 0.0195 M, and the concentration of NH3 was 0.430 M.
What is the dew point temperature of a gas mixture that is 30% n-hexane, 30% in-heptane, and 40% air at 1 atm? What is the composition of the first "drop"?
What are the normal boiling points of cyclohexane and toluene. Without looking up the actual value, which has a higher vapor pressure
