Two m^3 of xenon(Xe) are contained in a closed rigid tank at 70 degree C and 2 bar. The tank is heated to a pressure of 10 bar. Assuming that Xe behaves like an ideal gas with a specific heat ration of 1.7, calculate the final temperature of Xe in degree C
What happened when 6.0M HCl was added to the contents of the tube in 7a above?
A certain first-order reaction (A->product) has a rate constant of 7.50×10-3 at 45 . How many minutes does it take for the concentration of the reactant, , to drop to 6.25 of the original concentration?
Write a balanced chemical equation for the neutralization reaction upon which this titration is based, and indicate clearly which atom is being protonated. Then, calculate the equilibrium constant for the neutralization reaction.
After it reaches steady state, the iron is quickly cooled to room temperature. The carbon concentration at the carbon-rich surface is determined to be 8.415x10^0 at%
A long glass tube, sealed at one end, has an inner diameter of 10.0 mm. The tube is filled with water and inverted into a pail of water. If the atmospheric pressure is 774 mmHg, how high (in mmH2O) is the column of water in the tube
Water is composed of 11.2% hydrogen and 88.8% oxygen. What mass of water contains 16.0g of hydrogen?
if you have water of 330 ml at 25 degrees and then combine water of 130 ml at 95 degrees celsius temperature then
Equal volumes of 1 x 10-4 M solutions of Cd2+ and CO32- ions are mixed in one flask and equal volumes of 1 x 10-4 M solutions of Ag+ and CrO42- ions are mixed in a second. Which substances precipitate given that the Ksp values of CdCO3 and Ag2CrO4..
What is meant by this term and how does an amphipathic molecule behave in water. Draw a diagram to illustrate
Calculate how much primary standard KIO3 (FW=214.00259) must be dissolved to make 500mL of 0.01 M KIO3.
This is for two dimensional arrays with both positive and negations ions alternating in a square pattern. I am given the hint to select an area with boundries through the middle of the outermost ions-ie the edge ions count as 1/2
In a constant pressure calorimeter 25 mL of 1.0M NaOH reacts with 250 mL of 1.0M HCl and the temperature increases 6.0 degree celsius. What is the enthalpy of this reaction?
