Consider the following thermochemical equation: Fe2O3 (s) + 2 Al (s) → 2 Fe (s) + Al2O3 (s) ∆H = –1704 kJ. Determine the heat evolved, in kJ, when 16.8 g Al is consumed in this reaction. Show units!
Added by Ignacio S.
Step 1
First, we need to determine the amount of moles of Al consumed in the reaction. We can use the molar mass of Al to convert the given mass to moles: molar mass of Al = 26.98 g/mol moles of Al = 16.8 g / 26.98 g/mol = 0.622 mol Show more…

Determine the heat evolved (in kJ) when 15.0 g of Aluminum reacts with excess iron (III) oxide. Is this reaction endothermic or exothermic? Show your work. 2Al(s) + Fe2O3(s) → Al2O3(s) + 2Fe(s) ΔH°rxn = -849 kJ/mol

Calculate the ^H for the reaction 2 Al + Fe2O3 —— 2Fe + Al2O3 Using the following information: 2 Al + 3/2 O2 —— Al2O3. ^H = -1670 kJ 2 Fe + 3/2 O2 —- Fe2O3. ^H = -824 kJ

Refer to this equation: 2Al(s) + Fe2O3(s) --> 2Fe(s) + Al2O3(s) ΔHrxn = -847.6 kJ/mol rxn. How much heat is released if 35.0 g of Al(s) reacts to completion? 417. kJ 254 kJ 549 kJ 1870 kJ 3050 kJ 104 kJ 1490 kJ 439 kJ
