CaCO3 can be roasted to produce CaO and CO2. This reaction is carried out in a flask connected to an open-end mercury manometer when the atmospheric pressure is 767 torr. If the pressure of the CO2 produced is 0.215 atm, determine the total pressure in the flask AND the height difference between the two arms of the manometer.
Consider the titration of 46.0 mL of 1.2 M NaOH with 1.0 M HCl. Find the pH at the following points. A)After the addition of a large excess of acid
A 1.30 M solution of citric acid (H3C6H5O7) in water has a density of 1.10 g/cm3. Calculate the mass percent, molality, mole fraction, and normality of the citric acid. Citric acid has three acidic protons.
A gaseous mixture of O2 and N2 contains 30.8 nitrogen by mass. What is the partial pressure of oxygen in the mixture if the total pressure is 805 mmHg ?
What is the theoretical yield of aspirin if 190 kg of salicylic acid is allowed to react with 128 kg of acetic anhydride?
The partial pressure and Henry's law constants for SO2 and H2O2 are 2.7 ppm (KH = 1.2 mol L-1atm-1) and 4.9 ppb (KH = 1.0E5 mol L-1atm-1), respectively. Calculate the reaction rate of this process.
a 10.00-mL sample of sulfuric acid from an automobile battery requires 35.08 mL of 2.12 M sodium hydroxide solution for complete neutralization. what is the molarity of the sulfuric acid? sulfuric acid contains two acidic hydrogens.
a 27.7 ml sample of CO2 was collected over water at 25.0 degrees celcius and 1.00 atm.(the vapor pressure of water at 25.0 degrees celcius is 23.8 torr) What will the volume be at the same temperature and pressure after removing the water vapor?
Use this mass and the dilution volumes to calculate the ACTUAL molarity of the sulfuric acid in the INITIAL solution.
How many L of N2 gas are produced at STP when the airbag inflates if the airbag contains 132g of sodium nitride?
If a sample containing 3.00 mL of nitroglycerine (density = 1.592 g/mL) is detonated, how many total moles of gas are produced?
Steam distillation may be used to separate a mixture of p-nitrophenol and o-nitrophenol.
If 145.0 mL of 0.350 M lithium hydroxide is required to titrate 35.0 mL of an unknown monoprotic acid, what is the molar concentration of the unknown acid.
