Determine theoretical yield, limiting agent & excess reagent.
One form of phosphorous, called white phosphorous, burns when exposed to air.
P4(s) + O2 (g) à P4O10 (s)
a. Calculate the theoretical yield, in grams, of P4O10 produced from 67.820g P4 and 60.910g O2.
b. Identify the limiting reagent.
c. How much excess reagent remains after the reaction goes to completion?
How many grams of ammonia can be produced ? How much of the excess reactant is left over?
assuming that the gas behaes ideally. Then repeat the calculation by using the van der Waals equation
Crude gunpowders often contain a mixture of potassium nitrate and charcoal (carbon). When such a mixture is heated until reaction occurs, a solid residue of potassium carbonate is produced.
What is ?H in kJ for the combustion of 2.86 L of benzene producing CO2(g) and H2O? Assume that the heat of combustion of benzene is -4.18 x 103 kJ/mol. Enter your answer with three significant figures in exponential format (1.23 x 104 = 1.23E4).
To whats volume in liters must 105 mL of hydrochloric acid containing 47.5g of HCl be diluted to make a 1.05M solution ?
The flask is then rinsed with 64.6 mL of distilled water and is then used to prepare a standard solution of KNO3. Compute the molar concentration of Cl- in the standard KNO3 solution if the flask is rinsed only one time with distilled water.
If an unknown forms a silver mirror in the Tollens test, forms a purple color in the Schiff test, produces no precipitate in the iodoform test, has a refractvie index of 1.5250, and forms a semicarbazone melting at 124-126 C
Calculate the number of moles of HCl in the solution dispensed and its associated error.
How much HCl must be added to a liter of buffer that is 1.5 M in acetic acid and 0.75 M in sodium acetate
The vapor pressure of water above this solution is found to be 0.3624 atm at 348.0 K. The vapor pressure of pure water at this temperature is 0.3804 atm.
It is desired to inflate a baggie with a volume of 959 milliliters by filling it with hydrogen gas at a pressure of 0.544 atm and a temperature of 284 K. How many grams of H2 gas are needed?
