In the commercial manufacture of nitric acid, how many liters of nitrogen dioxide will produce 30 liters of nitric oxide given that both gases are at STP? 3NO2 + H2O-> 2HNO3 +NO
what mass of solid La(IO3)3 is formed when 50 ml of 0.250 M La are mixed with 75.0 ml of 0.302 M IO3-
Calculate the mass percent of a solution that is prepared by adding 32.2 g of NaOH to 262 g of H2O.
Explain how you arrived at this conclusions. Write a balance chemical equation for the reaction that occurs when sodium cyanide dissolves in water.
What volume (L) of 0.250M HNO3 is required to neuralize a solution prepared by dissolving 17.5g NaOH in 350mL of water?
Calculate the molar mass of a vapor that has a density of 6.735 g/L at 13°C and 825 torr.
ideal gas in 2.0 L what will be the volume of the gas if the pressure on the container is doubled while the temperature is reduced from 400 K to 200 K.
One mole of an ideal gas with Cv,m = 3R/2 initially at 325K and 1.5*10^5 Pa undergoes a reversible adiabatic compression. At the end of the process, the pressure is 2.50 * 10^6 Pa.
In a titration of HNO3, you add a few drops of phenolphthalein indicator to 50.00 mL of acid in a flask. You quickly add 26.50 mL of 0.0502 M NaOH but overshoot the end point, and the solution turns deep pink.
Determine the entropy change for freezing 6.33 grams of C 2 H 5 OH at 158.7 K? H =-4600 J/mol. Express your answer in units of J/K.
If you set the freezing point of oleic acid as 0 and the boiling point as 130, what is the freezing point of water on this new scale?
A 739 mL gas sample at STP is compressed to a volume of 244 mL, and the temperature is increased to 24 ?C. What is the new pressure of the gas in Pa?
Given the following two solutions: 0.200 M HC2H3O2(aq) with pKa = 4.76 0.200M NaOH(aq) A mixture is made using 50.0 mL of the HC2H3O2 and 25.0 mL of the NaOH. What is its pH?
