If 10.0 g of Al(SO), is reacted with 10.0 g of NaOH, determine the limiting reagent b. Determine the number of moles of Al(OH), produced c. Determine the number of grams of Na SO, produced d. Determine the number of grams of excess reagent left over in the reaction 3. Given the following equation: AlO, Fe FeO, Al a. If 25.4 g of Al,O, is reacted with 10.2 g of Fe, determine the limiting reagent b. Determine the number of moles of Al produced c. Determine d. Determine the number of grams of excess reagent left the number of grams of FeO, produced over in the reaction

Explanation / Answer

1)

balanced equation is

C3H8 + 5O2..........................> > 3 CO2 + 4 H2O

14.8 gm C3H8 = 14.8 / 44 = 0.336 mole.

3.44 gm O2 = 3.44 / 32 = 0.1075 mole.

O2 is the limiting reactant.

number of moles of CO2 produced = 3 * 0.1075 / 5 = 0.0645 mole.

grams of H2O produced = 4 * 0.1075 * 18 / 5 = 1.55 gm

excess reagent left = (0.336 - 0.1075 /5) = 0.3145 mole = 0.3145 * 44 = 13.8 gm
