You have two flasks of equal volume. Flask A contains H2at 0°C and 1 atm pressure. Flask B contains CO2 gasat 0°C and 2 atm pressure. Compare these two gases with respect to each of the following.
(a) average kinetic energy per molecule(H2:CO2)
(b) average molecular velocity (H2:CO2)
(c) number of molecules (Flask A:Flask B)
(d) mass of gas (Flask A:Flask B)
Assume that fructose is a molecular solid and does not ionize when it dissolves in water.
Most of the solid did not dissolve because the Ksp of ferric hydroxide is very small at 3 x 10^-39. However, when a certain amount of strong acid was added, the entire amount of solid dissolved. Determine the pH of the solution at that point that ..
You have a sample of helium gas at 0.00 ?C. To what temperature should the gas be heated in order to increase the root-mean-square speed of helium atoms by 10.0%
The hydrogen is slightly acidic, and it is often used as a primary standard for acid-base tritations because it is solid and air-stable, making it easy to weigh accurately. Its molecular formula is KHC8H4O4. Calculate how many mL of NaOH solution ..
The air is breathed underwater at 100 feet where the total pressure is 4.1 atm. What is the partial pressure (atm) of oxygen under these conditions? Calculate the relative rate of diffusion of CO2 compared to SO2.
In the reaction BaCO3 + 2HNO3 -> Ba(NO3)2 +CO2 + H2O, what mass of Ba(NO3)2 can be formed by combining 55 g BaCO3 and 26 g HNO3?
Consider the free radical brination of butane. Two monodbrominated producst are possible. Draw appropriate structure of each.
determine How many grams of Phosphine (PH3) can produce if 37.5 grams of P4(phosphorus) and 83.0 Litres of H 2 gas react at STP?
an Erienmeyer flask is closed by a stopper connected to a glass tube. the glass tube is sealed by a drop of mercury. if we move the whole appareatus in the diagram from a room with a temp. of of 26 degrees celcius to an outdoor yard with a temp of..
A solution of ammonia and water contains 3.20×10^25 water molecules and 8.10×10^24 ammonia molecules. How many total hydrogen atoms are in this solution?
The energy levels of hydrogenlike one-electron ions of atomic number Z differ from those of hydrogen by a factor of Z^2. Predict the wavelength of the transition
Ammonia condenses to form a liquid at -33.35C at atmospheric pressure. The density of liquid ammonia at this temperature is 0.6818g/ml. If the ammonia (0.224ml) is condensed at these temperatures, what would be its volume?
