What is the percent yield of a reaction in which 200 g phosphorus trichloride reacts with excess water to form 82 g HCl and aqueous phosphorus acid (H3PO3)
If Kp = 0.032 at this temperature, what will be the equilibrium overall pressure starting from pure CaSO4(s)?
A 4.867 g sample of a monoprotic acid was dissolved in water. It took 30.24 mL of a 0.1578 M NaOH solution to neutralize the acid. Calculate the molar mass of the acid.
A car travels at 58.0 miles per hour and gets 10.0 kilometers per liter of gasoline. How many gallons of gasoline are needed for a 1.00 hour trip.
How many grams of Ba(OH)2 will be needed to neutralize 76 mL of stomach acid if stomach acid is 0.14 M HCl?
Convert lb mol CaC2 feed to lb and calculate lb inerts added. The total lb solids in the slurry is then the sum of the Ca(OH)2 plus inerts. In calculating the water added, remember that some is consumed in the reaction.]
