Combustion of propane in the presence of oxygen yields carbon dioxide and water. The unbalanced equation is:
C3H8 (g) + O2 (g) image from custom entry tool CO2 (g) + H2O (g)
If 1.00 g of propane and 3.00 g of oxygen are reacted in a 1.00 L container at 227°C, determine
a) the limiting reactant.
b)the partial pressures of all gases and the total pressure, at the completion of the reaction.
c)the mass of excess reagent that will remain at the completion of the reaction
specify which indicator or indicators you would use for the following titrations. thymol blue, bromophenol blue, methyl orange, methyl red, chlorophenol blue, bromothymol blue, cresol red, phenolphthalein.
A 9-mm Xian short-barrel experimental pistol is fired and the reacting, exploding gases push the bullet down the barrel of the gun. The pressure is recorded as the bullet accelerates to the exit.
