Question

HI, can someone please help me. This is a Material Balance engineering question. I am looking for the material balance for the follow. This is the 3rd time I have asked this question and this "so-called" expert "Anonymous" continues to answer it with coping and pasting an article from wikipedia?? WTH Chegg??. PLEASE someone else help me! I do NOT need an essay about Ethanol. I need help with this problem.

1000 kg of Ethanol (CH3CH2OH) is dehydrogenated in air over a catalyst and the following reactions take place:

CH3CH2OH --> CH3CHO +H2

2CH3CH2OH + 3O2 --> 4CO2 + 6H2

the product, CH3CHO (acetaldehyde), leaves as a liquid.

MW of ethanol = 46 g/mol MW of acetaldehyde= 44g/mol

Question:

1. If 8 kmol of CO2 leaves the reactor, how many kg acetaldehyde (CH3CHO) is produced per kg of ethanol fed?

2. If the product gas contains 10 kmol O2, how much air was fed?

3. What is the total moles and molar composition of the output gas?

Please let me know how to do the steps and what you are doing.. Please.
