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 solution? Will it be too high, too low, or unaffected?
A nitric acid solution containing 71.0% HN)3 (by mass) has a density of 1.42 g/mL. How many moles of HNO3 are present in 1.00L of this solution?
A particular calorimeter is calibrated and is found to have a calorimeter constant, Ccal = 3.640 kJ/°C. When 1.500 g of an unknown hydrocarbon was combusted in the calorimeter
Calculate the freezing point of the following solutions, assuming complete dissociation. Part A= 0.114mK2S Part B=20.5g of CuCl2 in 401g water Part C=6.5% NaNO3 by mass
an ideal gas originall at 0.85 atm and 65 degrees celcius was allowed to expand until its final volume pressure and temperature were 94 mL, 0.60 atm, and 47 degrees celcius respectivily. What was its inital volume?!
Calculate the pressure inside the graduated cylinder it the height of the water is 5mm higher than the water in the trough. The atmospheric pressure is 760 mm Hg
if the pressure inside of the eudiometer is equalized to barometric pressure (0.987 atm), what is the pressure of the oxygen gas in the eudiometer?
Describe clearly why a single indicator solution in only useful for measuring pH over a rather narrow range. Use a specific indicator of solution
Atmospheric pressure decreases as altitude increases. In other words, there is more air pushing down on you at sea level, and there is less air pressure pushing down on you when you are on a mountain
When a charge transfer electrode reaction occurs at a very slow rate, the concnetration on the surface of the electrode is ____ than the bulk concentration.
The numbers above are also the only numbers I am given. I do not have delta G's of molar G's. If you have an answer that solves for the G's and shows me step by step how to solve the problem, you will get five stars.
calculate the equilibrium partial pressures of all gases in the reaction and set up the expression for Kp in terms of equilibrium partial pressures but do NOT solve.
