Time Remaining:03:33:52 1. Consider the following balanced equation: 502(g) + 2CH3CHO(1) -> 4CO2(g) + 4H2O(1) 11 95.2 moles of O2(g) and 33.9 moles of CH3CHO(I) are allowed to react, what is the theoretical yield of H2O() in moles? 65.9 moles 67.8 moles 35.4 moles 94.3 moles 446 moles Use the slider to rate your confidence on this question 100 26 Not at all confident Very confident Fe Liron Ru TOTO 70

Answer 1

From the balanced equation we can say that

5 mole of O2 requires 2 mole of CH3CHO so

95.2 mole of O2 will require

= 95.2 mole of O2 *(2 mole of CH3CHO / 5 mole of O2)

= 38.1 mole of CH3CHO

But we have 33.9 mole of CH3CHO which is in short so CH3CHO is limiting reactant

From the balanced equation we can say that

2 mole of CH3CHO produces 4 mole of H2O so

33.9 mole of CH3CHO will produce

= 33.9 mole of CH3CHO *(4 mole of H2O / 2 mole of CH3CHO)

= 67.8 mole of H2O

Therefore, the number of moles of H2O produced would be 67.8
