A would be correct. Hope i helped.
I had this question i got heterogeneous mixture
Since cells are hard to see the microscope helped them see. scientist were able to actually see cells in tissues placed under the microscope.
Ethyl butyrate is also more commonly known as the ethyl butanoate with chemical formula of C₆H₁₂O₂. The equation of the butanoic acid (C₄H₈O₂) and ethanol (C₂H₆O) to form this substance can be written off as,
C₄H₈O₂ + C₂H₆O --> C₆H₁₂O₂ + H₂O
Note that the given equation is already balanced. Using dimensional analysis and conversion factors,
(8.5 g C₄H₈O₂)(1 mol/88.11 g)(1 mol C₆H₁₂O₂/1 mol C₄H₈O₂)(116.16 g / mol)
= 112.06 grams of ethyl butyrate
ANSWER: 112. 06 grams
