Note that I dropped a - sign here on the change of -2x. The equil value of 0.1-2x is correct as written.
..........2H2S ==> 2H2 + S2
I am a freshman in college, and am taking a placement test soon, but haven't seen chemistry since 10th grade. I'd appreciate any help I can get from anyone here to help me solve this problem: Hydrogen and sulfur chemically combine
Write word equations for the following chemical reactions. a. Pure copper can be produced by heating copper(II) sulfide in the presence of diatomic oxygen from the air. Sulfur dioxide gas is also produced in this reaction. b.
An equilibrium was established after 0.100 mol of hydrogen gas and 0.100mol of iodine gas were added to an empty 1.00L reaction vessel and heated to 700K. The color intensity of the mixture changed from deep purple to a lighter
2H2(g) + S2(g) ¡ê 2H2S(g) Analysis of the contents of a 15.0L flask reveals that there are 4.4 moles of hydrogen gas, 2.0 moles of sulfur gas, and 3.7 moles of hydrogen sulfide gas in the flask at equilibrium. Calculate the
2. Solid ammonium iodide decomposes to yield ammonia gas(NH3) and hydrogen iodide gas at 400oF. The equilibrium constant for this reaction is 0.215. Ten grams of ammonium iodide are sealed in a 10.0 L flask at equilibrium.
When 0.20 mol of hydrogen gas and 0.15 mol of iodine gas are heated at 723 K until equilibrium is established, the equilibrium mixture is found to contain 0.26 mol of hydrogen iodide. The equation for the reaction is as follows.
Write Skeleton equations for these reactions. A) Heating Copper(II) sulfide in the Presence of diatomic oxygen produces pure copper and sulfur dioxide gas. B)When heated, baking soda (Sodium hydrogen carbonate) decomposes to form
methanol gas decomposes into carbon dioxide and hydrogen gas. At 327 degrees celcius, the equilibrium concentration are methanol is 0.15M, and hydrogen is 1.1M for the reaction calculate the Kp at this temperature.
a 4.22 gram sample of copper II sulfide was added to excess hydrocholoric acid with hydrogen sulfide gas being generated and collected over water. What volume of hydrogen sulfide gas would be collected at 32 degrees Celcius and
