From the solubility data given, calculate the solubility products for the following compound Ag3PO4, 6.7 x 10^-3 g/L
Problem- What name is given to the shape of a molecule with no lone pairs of electrons on the central atom and 6 electron domains on the central atom
You want to prepare a solution that is 0.200m in Na2CO3. How many grams of the salt must you add to 125g of water? What is the mole fraction of Na2CO3 in the resulting solution?
Benzoic acid had a percent recovery of 34% and 2-naphthol had a percent recovery of 85%. Why could this be? (ex. could it be that benzoic acid is a stronger acid and therefore more dissociation occurs, losing mass?)
He finds that the total pressure at equilibrium is 40% greater than it was originally. What is Kc for this reaction?
AgCl is found to have 78.1% ionic character, and its gas phase dipole moment is 11.5 D. What is the distance between the Ag and Cl atoms in gaseous AgCl?
P4(s) + 6F2(g) --> 4PF3(g) How many grams of fluorine are needed to react with 6.20g of phosphorus?
the amount of product (3.80 mol P2O5) formed from the given amount of phosphorus and excess oxygen. In Part B, you found the amount of product (3.40 mol P2O5) formed from the given amount of oxygen and excess phosphorus.
Calculate the pH after the following amounts of NaOH are added. A) 0mL NaOH added( before the titration started)
Consider 1 mole each of gaseous He and N2 at the same temperature and pressure. The diameter of N2 is 1.7 times that of He. State which gas (if any) has the greater value for: a) ; b) crms; c) average translational energy ; d) Z1; e) Z11; f) de..
the ejected electrons have the speed v=1.06x10^6 m/s. What will be the speed of the electrons ejected from the same metal by a light of wavelength 180nm?
The reaction caused the temperature of the solution to rise from 24.09 °C to 27.16 °C. If the solution has the same density and specific heat as water, what is ΔH for this reaction (per mole of H2O produced)? Assume that the total volume is the su..
