Given: 0.250L of 0.575M Pb(NO3)2 solution mixed with 0.300L of 0.822M NaOH at 25c. Determine if a precipitate forms. I calculated the concentrations to be 0.144 mol of Pb(NO3)2 and 0.247 mol of NaOH. What do I do from here?
The resulting solution required 40.70 mL of 0.08765 M AgNO3(aq) to precipitate the Cl^- (aq) and Br^- (aq) as AgCl(s) and AgBr(s).
If a temperature scale were based on the freezing point (5.5 degrees celsius) and boiling point (80.1 degrees celsius) of benzene and the temperature difference between these points was divided into 50 units (called degrees X), what would be the f..
Which of the following molecules would a flame ionization detector (FID) be sensitive to after separation on a gas chromatography column?
Why was anhydrous not wet diehtyl ether used in the preparation and reaction of the grignard reagent
Consider the following cell: Pt|H2(g, 0.670 atm)|H (aq, ? M)||Ag (aq, 1.00 M)|Ag(s) If the measured cell potential is 1.15 V at 25 °C and the standard reduction potential of the Ag /Ag half-reaction couple is 0.80 V, calculate the hydrogen ion con..
350.0 mL of 2.50 M HCL are added to 400.0mL of 5.00 M HCL. Assuming that the volumes are additive, what is the final concentration
Calculate the equilibrium concentrations if the initial concentrations are 2.31M N2 and 0.54M O2. (This N2/O2 concentration ratio is the ratio found in air.)
Calculate the mass of silver chloride required to plate 215 mg of pure silver if silver chloride contains 75.27% Ag.
In covalent bond formation, electron sharing occurs between elements with relatively low EA and low IE. Please explain the answer as well.
Three gases (8.00 of methane, CH4, 18.0 of ethane, C2H6, and an unknown amount of propane, C3H8) were added to the same 10.0-L container. At 23.0 degrees Celsius, the total pressure in the container is 3.50 atm. Calculate the partial pressure of e..
What volume of H2O(g) is produced when 7.90 mo of C2H4 (g) reacts at STP? C2H4 (g) + 3O2 (g) ----> 2 CO2 (g) + 2 H20 (g)
Calculate the pH during the titration of 100.0 mL of 0.200 M HCl with 0.400 M NaOH. First what is the initial pH (before any NaOH is added
