At a fixed temperature, equal moles of SO2 (g) and O2 (g) are mixed in a constant pressure container (the volume of the container changes in order to keep the pressure at a constant value). The SO2 (g) and O2 (g) are allowed to react, producing SO3 (g):
2 SO2 (g) + O2 (g) → 2 SO3 (g)
If the initial volume of the container, before any reaction takes place, is 5.00 L, determine the volume of the container after the SO2 (g) and O2 (g) have reacted to completion.
The temperature of the cosmic background radiation is measured to be 2.7 K. What is the wavelength of the peak in the spectral distribution at this temperature
How many grams of CaCO3 are produced when you react 55.2 mL of 0.150 M Ca(NO3)2 with 0.655 g of Na2CO3? How many grams of Na2CO3 remain unreacted? How many grams of Ca(NO3)2 remain unreacted?
calculate the heat absorbed or lost by the aqueous solution qaq in joules assuming that the specific heat capacity
Arrange the following atoms in order of decreasing atomic radius. Rank from largest to smallest. To rank items as equivalent, overlap them. Ge, Si, I, O
When the two cylinders are connected and the gases mixed, the pressure in each cylinder becomes 8.71 atm. What is the volume of cylinder B?
A certain first-order reaction (products) has a rate constant of 6.90×10-3 s^{-1} at 45 C. How many minutes does it take for the concentration of the reactant, [A], to drop to 6.25% of the original concentration?
KEtones also undergo the aldo condensation, although a succesful reaction often requires "enhanced" conditions, since the addition involves an unfavorable equilibrium constant.
If a 0.10M solution of HA has a pH of 5.83 at 25 degrees C, what is deltaG0 for the acid's dissociation at 25 degrees C
How many mL of .200 M FeCl3 are needed to react with an excess of Na2S to produce 2.75 g of Fe2S3 if the percent yield for the reaction is 65%? 3Na2S + 2FeCl3 = Fe2S3 + 6NaCl
You have 1005.3 g of a bleach solution. The percent by mass of the solute sodium hypochlorite, NaOCl, is 3.62%. How many grams of solvent are in the solution?
When a He atom absorbs a photon to form the excited configuration 1s^1 2s^1 (here called He*) a weak bond forms with another He to form the diatomic molecule HeHe*. Construct a molecular orbital description of the bonding in this species.
