A flask contains a mixture of two ideal gases, A and B. Show graphically how the total pressure of the system depends on the amount of A present; that is, plot the total pressure versus the mole fraction of A. Do the same for B on the same graph. The total number of moles of A and B is constant.
In an experiment, equal volumes of 0.00200M FeCl3 and 0.00200M NaSCN were mixed together and reacted according to the equation:
An aqueous solution that contains 329 ppm of KNO3 is being used to feed plants in a graden. What volume (in mL) of this solution is need to prepare 9 L of a solution that is 23 ppm in KNO3?
What are the average calories (not Calories) per gram for each of your food items?
Why is toxicity diminished in other congeners where chlorines are removed from the 2,3,7,8 positions, or when chlorines are added to remaining positions on the rings?
Calculate the partial pressures of CO2 and CO at equilibrium if 5.0 g of CO2 are introduced into a 10.0 L container and heated to 1200 K in the presence of 1.50 g of graphite (C (s)).
Arrange the four compounds below in order of increasing volatility.
A specific brand of gourmet chocolate candy contains 7.00g of dietary fat in each 22.7-g piece. How many kilograms of dietary fat are in a box containing 2.00lb of candy?
A company is marketing a photovoltaic cell that it claims has an output of 320 W/m2 when tested at the standard 1000 W/m2 irradiation condition
if you added 75.0 ml of a 0.555 M solution of NaCl to enough water to produce 950.0 ml of solution, what would be the resulting molarity?
No desiccator is available. The sodium carbonate is cooled to room temperature, but the humidity in the room is high. how will this affect the reported molar concentration of the hydrochloric acid
Instead of 6 M NaOH being added to the test solution, 6 M HCl is added. How will this affect the test for the presence of ammonium ion in the solution? Explain.
At a pressure of 1.00 atm and a temperature of 20 degree Celsius, 1.72 g CO2 will dissolve in 1 L of water. How much CO2 will dissolve if the pressure is raised to 1.35 atm and the temperature stays the same?
