We are going to do the following steps:
Step 1: Calculate the moles of Fe
Step 2: Calculate the mass of Fe2O3
How many grams of Fe2O3(molar mass = 159.7 g/mole) are produced from the absorption of 4.85 x 103 J of heat according to the following balanced thermochemical equation?
4 Fe(s) + 3 O2(g) → 2 Fe2O3(s) ΔH = + 65.2 kJ
A. 11.9 g
B. 14.9 g
C. 23.8 g
D. 1.19 x 104g
