A mixture of methane CH4 and ethane C2H6 is stored in a container at 294 mmHg. The gases are burned in air to form CO2 and H2O. If the pressure of CO2 is 346mmHg at the same temp and volume as the original mixture, calculate the ratio of moles of CO2 produced to moles of the original gas mixture.
What is the dissociation constant, Kd, of a ligand with a percent occupancy (or fractional saturation) of 50% when [ligand] = 10-7 M
Complete combustion of a hydrocarbon is a reaction where oxygen reacts with the compound to yield carbon dioxide and water. What is the correct balanced equation for complete combustion of CH4
825grams of NO are produced from the reaction of 500grams of NH3 with excess oxygen, what is the percent yield?
Why should the flask be immersed in boiling water as much aspossible? What effect will it have in determining the molecularweight? Explain.
A gaseous mixture of O2 and N2 contains 36.8% nitrogen by mass. What is the partial pressure of oxygen in the mixture if the total pressure is 685 mmHg.
whose temperature is 95 C and which contains 130g of liquid. Assume the specific heat capacity of the coffee is the same as that of water. The heat of fusion of ice
solvents in addition to acetone could be used for extracting plant photosynthetic pigments
The temperature of the water rose t oa final temperature of 27.84 C. Neglecting heat loss to the room and the heat capacity of the beaker itself, what is the specific heat of the alloy?
2.00 moles of a gas occupies 62.2 L at a particular temperature and pressure. Its density is 0.900 g/L. The standard molar volume is 22.4 L/mole. What is the molar mass.
Calculate the molarity (mol/L) of Mn2+ when MnS is placed in a 0.0179 M (NH4)2S solution. The equation represents the solubility process.
How does an increase in pressure effect the solubility of a gas in a liquid? A. As pressure increases, gas solubility increases. B. As pressure increases, gas solubility remains the same. C. As pressure increases, gas solubility decreases.
