Question

What volume of oxygen gas is required to react completely with 0.716 mol of iron according to the following reaction at 0°C and I atm? iron (s) + oxygen(g) iron(II)oxide (5) liters oxygen gas

Answer 1

Reation : Fe (59 + The equation is not of Fe and Feo 0,19). balanud. Fe 0 (1) Adal 2 as the wefficient 2 Fe(5) + 0, 19) — a i 7 2 Fed (82 now, the equation is balanced. I w i mole of Og is required to completely react a moles of Fr. moi of moles of Oq available (nog) = nos of moles Of E Available in Fe2 = ? 0.716 mol . Mon - = MFe x mol O2 2 mol Fe 0.716 mol XL 2 0.358 mol O2 oral

1 atm oumpies 22.4 L volume. Imole of any gas at 0°c and Thurgone, volume og volume of O2 = no, x 2204h I MAI 0.358 mol x 22.14 L/mol 8.02 L = 8,02 L O2 gas is required
