A(g) + B(g) <--> C(g)
For which K= 1.30 x 10^2. Assume that .406mol C(g) is placed in the cylinder represented below. The tempurature is 300.0K, and the barometric pressure on the piston (which is assumed to be massless and frictionless) is constant at 1.00atm. The original volume (before the .406 mole C(g) begins to decompose) is 10.00L. What is the volume in the cylinder at equilibrium?
in the electrolysis of a sodium chloride solution, what volume of H2 is produced in the same time it takes to produce 257L of Cl2, with both volumes measured at 50 celcius degrees and 2.50atm
When sodium carbonate reacts with hydrochloric acid, the carbonic acid that is formed immediately breaks down into carbon dioxide and water.
A gaseous reaction occurs at a constant pressure of 40.0 atm and releases 68.0 kJ of heat. Before the reaction, the volume of the system was 9.00 L. After the reaction, the volume of the system was 2.00 L.
Why is molarity not the best means of stating acid strength? Is molarity the most representative form of quantifying acids and bases?
What is the pH of the buffer after the addition of 0.02 mol of NaOH? C)What is the pH of the buffer after the addition of 0.02 mol of HI? Express Numerically
An excess of NaOH is treated with 1.1L of dry HCl gas (measured at STP). What is the weight of NaCl formed?
Talc is a mineral that has low conductivity for heat and electricity and that is not attacked by acid. It is used as talcum powder and face powder. A sample of talc weighs 35.97 g in air and 13.65 g in mineral oil (d = 1.75 g/cm3). What is the den..
Identify the oxidation-reduction reactions among the following: 1. Zn(s) + Cu2+(aq) → Zn2+(aq) + Cu(s)
In an experiment where aniline is reacted with acetic anhydride to form acetanilide, how do you calculate the theoretical yield of acetanilide?
Hypochlorite Oxidation of Cyclohexanol to Cyclohexanone, Basically in this experiment, we took some cyclohexanol and reacted it with hypochlorite to form cycohexanone.
The iron content of hemoglobin can be determined by converting the iron to Fe2+ and titrating using MnO4 -. A 5.0 g sample of hemoglobin requires 21.6 mL of 0.00310 M potassium permanganate. What is the percent of iron in the hemoglobin sample?
If the propanoate ion comes from strontium propionate, Sr(C3H5O2)2 then how many grams of strontium propanoate are needed? Assume it is completely soluble.
