Question- A sealed 2 L container at 20.0 degrees Celsius hold 150g of ammonia (NH3). 150g of carbon dioxide (CO2) and 150g of Nitrogen (N2). What is the total pressure in atmosphere? show your work.
Please illustrate work if possible thanks
Utilize the atomic radius (70 pm) and density of neon at 25 C and 1 atm (.90 g/mL) to Compute the average density of a neon atom
A lactic acid/lactate ion buffer solution contains 0.24 M HC3H5O3 and 0.82 M C3H5O3^-, respectively. The Ka value of lactic acid is 1.4*10^-4. Calculate the of this buffer. Express the pH numerically.
A hypothetical element consists of two isotopes of masses 86.95 amu and 88.95 amu with abundances of 35.5% and 64.5%, respectively. What is the average atomic mass of this element?
Consider the titration of 41.2ml of 0.270M HF with 0.180M NaOH. Calculate the ph at each of the following points. how many milliliters of base are required to reach the equivalence point?
Consider the standard cell at 25 degrees Celsius based on the following half reactions. Pb^(2+) + 2e- > Pb Eofcell = -0.13V Zn^(2+) + 2e- > Zn Eofcell = -0.76V To the STANDARD CELL, OH-, is added to the zinc compartment causing precipitation of Zn..
What is the equivalence point volume? What is the cell potential at each of the following volumes of added Ce4+ ?
With water as a solvent, determine the molality of the solution required to produce a change of temperature equal to 2 ºC
The calorimeter contains exactly 281 g of water, and the temperature increases by 1.126°C. Calculate the heat given off by the burning Mg, in kJ/g and in kJ/mol.
explain the trends in melting points in going from the chloride to the flouride, making direct reference to the attractive forces that must be overcome to melt the solid and why their strength varies.
For steady flow in a heat exchanger at just about atmospheric pressure, explain what is the heat transferred. Explain when 20 mol of ammonia is heated from 100 to 800 deg. C
"A sample of a particular radioisotope is placed near a Geiger counter, which is observed to register 160 counts per minute. Eight hours later the detector counts at a rate of 10 counts per minute. What is the half-life of the material?"
