Calculate th pH of 1.00 L of a buffer of 1.00 M CH3COONa/1.00 M CH3COOH to which 0.210 mol of NaOH has been added
Determine how many moles of carbon dioxide should be combined to the system to bring the equilibrium carbon monoxide concentration to 0.715 mol/L?
Iron is obtained commercially by the reaction of hematite (Fe2O3) with carbon monoxide. How many grams of iron is produced when 25 mol of hematite reacts with 30 mol of carbon monoxide? with the balanced equation of Fe2O3 + 3CO = 2Fe + 3CO2
What are the percentages of each molecular ion? (List to nearest 1% in order of increasing mass separated by commas, e.g. 55,45.)
A bottle containing 305 g of cleaning solution is used for carpets. If the cleaning solution has a specific gravity of 0.850, what volume of solution was used?
Create an outline of a procedure to use to create a kinetic plot of concentration vs time for the bleaching of a food dye. The outline must contain no more than 10 steps. Make sure to include the glassware and amounts of solutions you expect to us..
Alcohols are less volatile than ethers of the same molecular weight, but the two classes of compounds have approximately the same solubility in water because:
Explain why dichloroethene has a boiling point of 60 degrees C while trans-dichloroethene as a boiling point of 48 degrees C. Include drawings of the structures with dipoles in your answer.
How many moles of PCl_5 can be produced from 21.0 g of P_4 and excess Cl_2?
What is the pH of a propanoic acid - propanoate buffer that is 0.25M in CH3CH2COONa and 0.15M with respect to CH3CH2COOH.
At a certain temperature and pressure 2.8 L of N2 reacts with 4.2 L of O2. If all the N2 and O2 are consumed, what volume of N2O3, at the same temperature and pressure.
A gas is collected over water at a certain temperature. The total pressure is 762 torr. The vapor pressure of water at this temperature is 17 torr.
The biochemical oxygen demand (BOD) is the capacity of organic and biological matter in natural water to consume oxygen. It is determined experimentally by measuring the oxygen concentration in a sealed sample before and after a 5-day incubation p..
