The volume of fluorine gas required to react with 2.67 g of calcium bromide to form calcium fluoride and bromine at 41 ºC and 4.31 atm is how many mL?
Without a catalyst, a different reaction predominates: 4NH3(g) + 3O2(g) ? 2N2(g) + 6H2O(g) When 0.0230 mol gaseous NH3 and 0.0250 mol gaseous O2 are placed in a 1.00 L container at a certain temperature, the N2 concentration at equilibrium is 2.20..
Explain how you would prepare each of the following compounds from benzene:
a liter of solution contains .10 mol of Ag+ and .10 mol of Ba+2. if a highly concentrated solution of K2CrO4 is added drop by drop which will precipitate first. Ag2CrO4 or BaCrO4
Think back to what you learned in this course about solutions and intermolecular forces. Why don't these to "mix" together (in other words, make a homogenous solution) when combined. Why do they separate into layers
An unknown element forms a yellow ion, XO . It forms a precipitate with silver ions. If 48.0 mL of a 0.250 mol/L solution of silver ions is added to a solution of the unknown ion, 1.856g of a red-brown precipitate are formed. Determine the iden..
Carbon monoxide and water vapor, each at 190 Torr, were introduced into a 250 mL container. When the mixture reached equilibrium at 690 ?C, the partial pressure of CO2(g) was 108 Torr.
A specific brand of gourmet chocolate candy contains 7.00g of dietary fat in each 22.7-g piece. How many kilograms of dietary fat are in a box containing 2.00lb of candy?
The first step of the fischer esterification involves protonation of the oxygen of the carboxylic acid by the acid catalyst:
As a separation and detection method, would TLC or paper chromatography yield better results in the analysis of each of the following pairs of compounds
5 moles of sodium bromide NaBr is mixed with 3 mole of butanol CH3CH2CH2OH to yield 99 g of bromobutane CH3CH2CH2CH2Br
A system consists of an ideal monatomic gas initially at temperature 300.0 K, volume 4.000 L, and pressure 4.000 bar. For the following process, calculate the final values of T, P, V, q, w, ?U, and ?H.
