In the course of pumping up a bicycle tire, a liter of air at atmospheric pressure is compressed adiabatically to a pressure of 7 atm. (Air is mostly diatomic nitrogen and oxygen.)
(a) What is the final volume of this air after compression?
(b) How much work is done in compressing the air?
(c) Ifthe temperature of the air is initially 300 K, what is the temperature after compression?
The air pollutant NO is produced in automobile engines because of the high-temperature reaction below. If the initial concentrations of N2 and O2 at 1000 K are both 1 M, what are the concentrations of NO, N2, and O2 when the reaction mixture reach..
Balance the following example of a heterogeneous equilibrium and write its reaction quotient , Qc: KNO3(s)...........>
a solution of a and b with 30 mole percent of a is in equilibrium with its vapour which contains60 mole percent of a.
2HCrO4 ^- Cr2O7 ^2- + H2O Determine concentrations of Dichromate ion and Bichromate ion if we add .1mol/L of bichromate ion and no dichromate ion once reaction reaches equilibrium.
Determine the value of Kc for the following reaction if the equilibrium concentrations are as follows: [N2]eq = 3.6 M, [O2]eq = 4.1 M, [N2O]eq = 3.3 × 10-18 M.
An impure sample of copper sulfate weighing 5.52 grams was dissolved in water and allowed to react with excess zinc. CuSO4(aq) + Zn(s) = ZnSO4 (aq) + Cu(s) What is the percent CuSO4 in the sample if 1.49 grams of metallic copper was produced
moles of benzoyl peroxide and another person used the same amount of benzoyl peroxide as the first person but only used 150 moles of styrene, what would be the average molecular weight of each groups polymer sample be?
A buffer contains 0.15 mol of propionic acid C2H5COOH and 0.13 mol of sodium propionate C_2 H_5 COONa in 1.20 L.
Americium-241 is used in smoke detectors. It has a first order rate constant for radioactive decay of k=1.6 x 10^-3 yr^-1. By contrast, iodine-125, which is used to test for thyroid functioning, has a rate constant for radioactive decayof k=.oo1 d..
In general, oxides of elements further to the left on the periodic table are basic, moving toward acidic on the right. For nonmetallic oxides, when the oxidation number of the element other than oxygen is high, the oxide tends to be acidic. When t..
