At what temperature degrees C will xenon atoms have the same average speed that Cl2 molecules have at 25 degrees C?
Identify the original liquid and write a structure for the solid derivative. After identifying the unknown liquid, can you indicate what the structure of the precipitate obtained on reaction with bromine might be?
If the propanoate ion comes from strontium propionate, Sr(C3H5O2)2 then how many grams of strontium propanoate are needed? Assume it is completely soluble.
Write an equilibrium expression for each chemical equation involving one or more solid or liquid reac- tants or products.

Enter que Determine the following characteristics of the titration curve for 25.0 mL of 0.400 M NH3(aq) titrated with 0.335 M HI(aq). (For NH3, Kb = 1.8x10-5.) Enter scientific notation as 1.23E4.
Use a drawing program to draw a beaker.
A copper, Cu(s), electrode is immersed in a solution that is 1.00 M in ammonia, NH3, and 1.00 M in tetraamminecopper(II), [Cu(NH3)4]^{2+}. If a standard hydrogen electrode is used as the cathode, the cell potential, Ecell, is found to be 0.059 V a..
Could someone please explain why synthesized soap and detergent have different reactions when they are mixed with calcium chloride
Show that the balanced equation obeys the law of conservation of mass.
What is the difference (in pH units) between the initial pH of a 0.20 M NH3 / 0.20 M NH4Cl buffer to the pH of the buffer after the addition of 10.0 mL of 0.10 M HCl to 65.0 mL of the buffer
A 50.0-g piece of metal at 203oC is dropped into 400.0 g of water at 25.0oC. The water temperature rises to 29.0oC. Calculate the specific heat of the metal (J/goC). Assume that all of the heat lost by the metal is transferred to the water and no ..
