I choose the option A.
The electron absorbs energy from specific wavelength then moving from a lower energy orbital to a higher energy orbital.
Animals use oxygen to convert this food into energy they can use, and to maintain a steady supply of carbon atoms that are necessary for building any animal cells. Respiration also returns carbon dioxide back to the atmosphere as a waste product, where plants can reabsorb it in the process of photosynthesis. hope I helped.
The answer will be, so3 since s only need two electrons to complete its octet
Answer:
C5H12.
Explanation:
The compound will be C5H12.
Now consider the general formula for the combustion of an alkane;
CnH2n+2 + 3n+1/2O2-----> nCO2 + (n+1) H2O
If we substitute n=5, we have;
C5H12 + 8O2-----> 5CO2 + 6H2O
Hence the answer above.
