Step 1
The molar mass of Fe is approximately 55.85 g/mol and the molar mass of O is approximately 16.00 g/mol. Therefore, the molar mass of Fe2O3 is (2*55.85) + (3*16.00) = 159.7 g/mol. Show more…

How much heat in kilojoules is evolved or absorbed in the reaction of 2.50 $\mathrm{g}$ of $\mathrm{Fe}_{2} \mathrm{O}_{3}$ with enough carbon monoxide to produce iron metal? Is the process exothermic or endothermic? $$ \begin{aligned} \mathrm{Fe}_{2} \mathrm{O}_{3}(s)+3 \mathrm{CO}(g) \longrightarrow 2 \mathrm{Fe}(s)+3 \mathrm{CO}_{2}(g) & \Delta H^{\circ}=-24.8 \mathrm{kJ} \end{aligned} $$
Suppose 391 kJ of heat is released when carbon monoxide gas reacts with nitrogen monoxide gas according to the thermochemical equation below: 2 CO(g) + 2 NO(g) → 2 CO2(g) + N2(g) ΔHrxn = -746.6 kJ. How many grams of carbon monoxide were consumed during this reaction?

In the following reaction, how much heat (in kJ) is released when 3.21 moles of CH₄ are burned? CH₄ (g) + 2 O₂ (g) → CO₂ (g) + 2 H₂O(g) ∆H° = -802 kJ/mol
