Approximately (3.230×10^0) g of lead(II) acetate, Pb(CH3COO)2,is weighed out and placed in a (2.85×10^2) mL solution of 0.150-mol/L sodium hydroxide. Calculate the mass of precipitate produced in this reaction. Note:Your answer is assumed to be reduced to the highest power possible.

Consider the following concentration cell.M(s) | M+(satd MX) || M+(0.100 M)| M(s) Ecell = 0.417 VAt the anode, a metal electrode (M) is placed in a saturated aqueous solution containing ions of the same metal (M) and a halogen (X), MX. At the cathode, a second electrode of the same metal (M) is placed in a solution with [M+] = 0.100 M.The two half-cells are […]

Consider the following reaction:H2O(g) + CO(g) H2(g) + CO2(g)The equilibrium constant Kp for this reaction is 0.55 at 1023 K.In a reaction vessel, water vapour and carbon monoxide are introduced at a pressure of 3.50 atm, and allowed to reach equilibrium at 1023 K.Construct a table and use it to calculate the partial pressure of all the gases at equilibrium.

If 15.0 g of H2 reacts with excess N2 according to the following equation what would the pressure of NH3 made be if it were trapped in 2.00 L at 35.0oC:N2 (g) + 3H2 (g) — 2NH3 (g) (GS not EQ thus stoich first and then PV=nRT and the value ofR=0.0821 L*atm/mol*K and 0oC = 273K)
