Answer:
Δ
Explanation:
Hello,
Butane's combustion is:
Now the change in the Gibbs free energy for this reaction is computed via (don't forget that oxygen's Gibbs free energy of formation is 0 since it is an element):
Δ
4Δ
5Δ
-Δ
Δ
Δ
Now, since the calculation is done for 1 mol of butane, the change in the Gibbs free energy for this fuel is:
Δ
Best regards.
Answer:
9-10 ppm.
0.2-0.4 ppm.
Explanation:
The proton on the aldehyde group will appear at approximately 9-10 ppm whereas the methylene peak on the alcohol is the only peak 0.2-0.4 ppm for either compound. Aldehydes and aromatics are quite distinctive in the Nuclear magnetic resonance (NMR). Aldehydes show up from 9-10 ppm, usually as a small singlet; aromatic protons show up from 6.5-8.5 ppm. NMR spectroscopy is the use of NMR to study the physical, chemical, and biological properties of matter.

Answer:
X represents oxygen and Y represents carbon dioxide.
Explanation:
Because in respiration, you consume oxygen and make carbon dioxide whereas, in photosynthesis, the equation is reversed and you use carbon dioxide and make oxygen and glucose.
