The reusable booster rocket of the U.S. space shuttle employs a mixture of aluminum and ammonium perchlorate for feul. the chemical reaction that occurs is:3Al +NH4ClO4--->Al2O3+AlCl3+3NO+6H2OIf in the feul mixture 15.0g Al reacted with 25.0g of NH4ClO4 to produce 5.67g AlCl3, what is the percentage yield for the reaction? [Al=26.98, N=14.01, H=1.01, Cl=35.45, O=16.00]
