A compound of a transition metal and iodine is 65.1% metal by mass. How many grams of iodine is present in 859 g of this compound?
Show whether or not precipitate will form in this process when the Ksp of Pbl = 9.8*10 -9
Explain the following: a.) The cycloheptatrienyl anion is antiaromatic, whereas the cyclononatetraenyl anion is planar (in spite of the angle stain involved) and appears to be aromatic. b.) Although
What is the boiling point of a solution made using 813g of sucrose, C12H22O11, in 0.275 kg of water,H2O.
A Chem 113 TA prepares a solution by dissolving 3.11 g of solid KOH in enough water to make 100.0 mL of solution. Calculate the molarity of K+ ions in this solution.
A mysterious material was purified from safflower oil (hint: full of fatty acids). Upon ozonolysis it gave the following compounds in their respective molar ratios.
A gas occupying a volume of 248 mL at a pressure of 0.970 atm is allowed to expand at constant temperature until its pressure reaches 0.541 atm. What is its final volume.
a gas sample occupies 4.20 l under a pressure of 800 torr at 350K.At what temperature will it occupy 3.60 L at the same pressure?
Determine the enthalpy change for the oxidation of ethanol to acetic acid, CH3CH2OH() + O2(g) -> CH3COOH() + H2O() given the thermochemical equations below.
Why can't i reduce carboxylic acid using sodium borohydride while lithium aluminium hydride can do the same thing.
A 0.456 gram sample of an unknown monoprotic acid (let's call it HZ) was dissolved in some water (you pick the amount). Then the acidic solution was titrated to the equivalence point with 32.5 mL of 0.174 M KOH.
