Extensive hydrogen bonding.
It takes a lot of energy to break hydrogen bonds and turn liquid water into a gas, therefore the boiling point for water is high.
Thus we can balance the oxygen atoms by putting a prefix of 25/2 on the left side. To obtain a equation containing whole numbers, we multiply the entire equation by 2. This gives the final equation. 2 C8H18 + 25 O2 ---> 16 CO2 +18 H2O.
Answer:
the answer is cobalt and chloride
