Use the balanced chemical formula below to answer the following problem using dimensional analysis. Report answers with unit, substance, and corre number of significant figures. Use mol for moles and g for grams. 3 Mn + Al.(CO.), --> 2 Al + 3 MNCO, How many moles of manganese are needed to react with 12.2 moles of aluminum carbonate?

Consider the stoichiometry of the reaction provided in the question(s) below. a. A laboratory student started with 0.0812 grams of Reactant A (benzaldehyde, m.w. 106.12 g/mol). How many millimoles of Reactant A did the student add to the reaction mixture? b. A laboratory student started with 0.162 grams of Reactant B (sodium chromate, m.w. 161.97 g/mol). How many millimoles of reactant B did the students add to the reaction mixture? c. Which of the reactants is the limiting reagent? d. After running the reaction, the student isolated 0.0733 grams of signal product (benzoic acid, m.w. 122.12 g/mol). How many millimoles pf product did the student isolate? e. calculate the % yield of this reaction

Im stuck on the last three questions

Use the References to access important values if needed for this question. For the following reaction. 5.63 grams of iron(III) oxide are mixed with excess aluminum. The reaction yields 2.88 grams of aluminum oxide. Fe₂O₂ (s) + 2Al(s) Al₂O, (s) 2Fe (s) (1) What is the theoretical yield of aluminum oxide? (2) What is the percent yield for this reaction? % grams
