2) Chromium metal and oxygen gas combine to form chromium (ui) oxide. a. How many moles of oxygen react to \( 10.0 \mathrm{~g} \) of chromium? arseg o.144moto b. How many grams of chromlum (iii) oxide are produced when \( 24.8 \mathrm{~g} \) of chromium metal reacts? c. When \( 26.0 \mathrm{~g} \) of chromium metal react with \( 8.00 \mathrm{~g} \) of oxygen gas, how many grams of chromium (III) oxide can be produced? d. If \( 74.0 \mathrm{~g} \) of chromium metal and \( 62.0 \mathrm{~g} \) of oxygen gas are mixed, and \( 87.3 \mathrm{~g} \) of chromium (III) oxide is obtained, what is the percent yield of chromium (III) oxide for the reaction? \[ 109.19 \mathrm{Cr}_{3} \mathrm{O}_{3} \rightarrow \text { ?1.0:1yitld } \]
