Carbon disulfide burns with oxygen to form carbon dioxide and sulfur dioxide in the following manner:
CS2 + 3O2 → CO2 + 2SO2
What is the volume of sulfur dioxide (SO2 gas), formed when 2 moles of carbon disulfide (CS2) are burned
Suppose that 0.92 of water condenses on a 85.0 block of iron that is initially at 22. If the heat released during condensation goes only to warming the iron block, what is the final temperature (in ) of the iron block? (Assume a constant enthalpy ..
Use the values of Ka1 = 0.056 and Ka2 = 5.4 x 10-5 to calculate the [OH-] in a 0.898 M solution of oxalic acid (H2C2O4). Use E notation and 3 significant figures.
How many different types of resonance structures can be drawn for the ion SO32.
Consider the titration of 50.0 mL of 0.217 M HN3 (Ka = 2.6 x 10-5) with 0.183 M NaOH. Calculate the pH of the solution after the addition of 29.6 mL of NaOH solution.
Give Structures- Indentify unknown organic liquids, An unknown organic liquid, A, was found to burn with yellow, sooty flame and give a positive Lucas test (about 5 min). Upon treatment with sodium dichromate-sulfuric acid solution it produced Comp..
a compound gives a mass spectrum with peaks at mz 77 40 112 100 114 33 and essentially no other peaks. identify the
what is the wavelength emitted due to an electron moving from an infinitely far orbit (n=infinity) to n=2? in what region of the electromagnetic spectrum is this wavelength
Calculate the vapor pressure of water, in torr, above a solution prepared by dissolving 62.60 g of ZnCl2 in 429.0 g of water at 328.0 K. The vapor pressure of pure water at 328.0 K is 118.0 torr.
the water for the pan is not saturated with CO2. Will the reported percent CaCO3 in the original sample be too high, too low, or unaffected? Explain
The determination of iron in industrial waste stream is often carried out by reacting the water sample with o-phenanthroline to form a red-orange complex that absorbs at 510 nm.
consider a stone column 3.00 ft in diameter and 10.00 ft high. What is is mass in pounds if its density is 3.50 g/mL.
Write the electron configurations for the following ions. You should use the noble gas abbreviations: Te2-, Mg+, As+, I-, Fe3+, N3-, Sn4+, Tl4+
