Determine the theoretical and percent yields of ethanol if 684 g sucrose undergoes fermentation and 349 g ethanol is obtained?
2C4H10 + 13O2 → 8CO2 + 10H2O The equation shows the combustion of butane (C4H10). How many moles of water can be produced by 12.5 moles of C4H10 with excess oxygen?
An experiment requires 42.0 g of ethylene glycol, a liquid whose density is 1.114 g/mL. Rather than weigh the sample on a balance, a chemist chooses to dispense the liquid using a graduated cylinder.
20.0ml of 0.150M Zn(NO3)2 are mixed with 20.0ml of 1.00 x10-4M Na2S. Calculate the amount of milligrams of ZnS (s) that will precipitate. (Ksp = 1.6 x10-24)
the pH of a saturated solution of a metal hydroxide MOH is 10.85 calculate the Ksp for the compound
A total of 2.00mol of a compound is allowed to react with water in a foam coffee cup and the reaction produces 188g of solution. The reaction caused the temperature of the solution to rise from 21.0 to 24.7 degrees Celsius .
