Given the balanced reaction: 4A1 + 302 > 2A1203 A student started with 3.0 grams of aluminum and excess oxygen. If she
produced 4.6 grams of aluminum oxide, Al2O3, what was her percent
yield?
Molar mass of Al2O3 is 102 grams.
% yield = (actual/theoretical)*100
A. 41 %
B. 81 %
C. 122 %
D. 93 %

In a water molecule, hydrogen and oxygen are held together by a(an) bond. a) double covalent b) ionic c) nonpolar covalent d) hydrogen e) polar covalent

Astudent reacts 13 moles of iron with 21 moles of oxygen according to the following equation:
