1.Even at high temperatures, the formation of NO is not favored:
(Kc = 4.10 × 10-4 at 2000°C)
N2(g) + O2(g) ? 2 NO(g)
What is [NO] when a mixture of 0.20 mol of N2(g) and 0.16 mol of O2(g) reach equilibrium in a 1.0-L container at 2,000°C?
2. Hydrogen iodide decomposes according to the reaction
2 HI(g) ? H2(g) + I2(g)
A sealed 1.50-L container initially holds 0.00623 mol of H2, 0.00414 mol of I2, and 0.0244 mol of HI at 703 K. When equilibrium is reached, the concentration of H2(g) is 0.00467 M. What are the concentrations of HI(g) and I2(g)?
[I2]eq M
[HI]eq M
What is the molarity of an aqueous solution containing 75.3 g of glucose (C6H12O6, mol wt = 180 g/mole) in 35.5 mL of solution
Problem- Consider the ion dichlorodiethylenediaminecobalt (I). What is the hybridization of the Co. Are any of the possible isomers chiral? If so draw them.
2- deoxyglucose is an analogue of glucose that has shown promise as a anti-cancer drug. The molecule can be phosphorylated by hexokinase, and regulates the activity of hexokinase. However, 2-deoxyglucose is not a substrate for glucose-6-phosphate ..
A sample of H½O with a mass of 46.0 grams has a temperature of -58.0 C. How many joules of energy are necessary to melt 46.0 grams of ice? (Use 2.1 J/g.C for the specific heat of ice, and 334.4 J/g for the heat of fusion of water.)
the second one volume is 60 and pressure 658psia we want to join them togother in one pipline what is the final equilibriume pressure?
Assuming that the specific heat of the solution is 4.18 J/(g*C) and that the calorimeter itself absorbs a negligible amount of heat, calculate delta H in kilojoules for the reaction
A gaseous system undergoes a change in temperature and volume. What is the entropy change for a particle in this system if the final number of microstates is 0.828 times that of the initial number of microstates. attempted on my own and came up wi..
The absorbance of a chlorophyll a standard solution in ethanol (density = 0.785 g/mL) is measured in a 1.3 cm cuvette or path length. The absorbance is 0.435 and the molar absorptivity coefficient is 86,300 M-1cm-1. The molecular weight for chloro..
