<u>Answer:</u>
0.800 moles of will be produced when 0.400 moles of react and are decomposed
<u>Explanation:</u>
The decomposition of (aq) ------> 2C2H5OH (aq) + 2CO2
¬moles of = 0.400 moles
Moles of produced will be calculated by the formula,
Moles of CO2 = 0.400 moles of
Substituting the values,
Moles of = = 0.400*2 = 0.800 moles
Therefore, 0.800 moles of will be produced when 0.400 moles of react and are decomposed
