In heavily populated areas, such as Los Angeles, the phenomenon of acid rain is very prominent due to the large amount of carbon dioxide emission into the atmosphere via vehicles, factories, and other emitting sources. When carbon dioxide is exposed to water vapor in the atmosphere, it will create carbonic acid. The acid then condenses further into a liquid and falls from the sky in the form of acid rain. Acid rain has the ability to corrode structures, damage vehicles, and cause chemical burns on humans & animals if the concentration is high enough.
Create and balance the chemical equation that describes the process in the
scenario above.
CO2 +Н2O –> H2CO3

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
