An acid solution contains 18 kg of water and pure hydrochloric acid (HCl). Its
concentration is 0.60 mol/kg of solvent. Compute for the number of moles of solute contained in the solution
When 1.50 mol of CO2 and 1.50 mol H2 are placed in a 3.00-L container at 395ºC, the following reaction occurs: CO2(g) + H2(g) ↔ CO(g) + H2O(g).
If Kc = 0.802, what are the concentrations of each substance in the equilibrium mixture?
What is the normality of a 500 mL solution containing 1.63 g of Pb(NO3)2 and used to precipitate out PbS? Pb(NO3)2 has a formula weight of 331.20 g/mol.
If 10 grams of butane(C4H10), afuel in cigarrete lighter, react with 10 grams of O2, how many grams of the product will be formed
how many moles of NaAlO2 are produced if 126.4 g of NaOH reacts completely?
an aqueous solution of NaOH can dissolve an aluminum sheet in the reaction:
2 Al + 2 NaOH + 2H2O → 2 NaAlO2 + 3H2
1.00 mole sample of NOCl was placed in a 2.00 L reactor and heated to 227oC until the system reached equilibrium. The contents of the reactor were then analyzed and found to contain 0.056 mole of Cl2. Calculate K at this temperature. The equation is as follows: 2NOCl(g) ⇌ 2NO(g) + Cl2(g).
The decomposition of NO2 is a second order reaction and the rate constant is 0.755 L/mol-s. In an experiment, the initial concentration of NO2 was 0.00650 mol/L. How many seconds will it take for the concentration of NO2 to drop to 0.00100 mol/L?
What is the HOMO for C2
Calculate the mass of Na2O that forms if 4,8g O2 reacts completely with sodium
