During biogenesis on earth carbon in all life primarily came from
a. carbon dioxide
b. water vapor
c. decaying organisms
d. methane
Homework Answers
a. carbon dioxide
During the early times of origin of life on earth, the earth was filled mostly with the molecular nitrogen and carbon dioxide but not methane. Water vapor does not contain carbon and the decaying organisms serve carbon, but this is not the case with the biogenesis (still the life is being formed during this period and also it is not the primary source).

Why is carbon preferable to be the chemical base for life? a. Carbon dioxide is essentially insoluble in water. b. Carbon dioxide is a strong construction material. c. The stability and strength of the carbon–carbon bonds make it a good base for larger molecular complexes. d. It escapes the biochemical circulation once it is utilized. e. By reacting with hydrogen, it can undergo combustion, which provides organisms with energy.

Greenhouse gases occur naturally in the atmosphere, such as carbon dioxide, water vapor, methane, nitrous oxide, and ozone. However, greenhouse gases are also produced due to human activities, such as driving (using oil) and coal plants. Do you think the earth is experiencing an anthropogenic (human-caused) climate change from our use of nonrenewable energy such as coal or oil?

Carbon dioxide is collected over water at a temperature of 11 ˚C. The pressure of water vapor at 35 ˚C is 42.2 torr. The pressure of the collected gas (water vapor + carbon dioxide) has a pressure of 0.789 atm, what is the pressure of the carbon dioxide in atmospheres (atm)?
Methane gas and oxygen gas react to form water vapor and carbon dioxide gas. What volume...
Methane gas and oxygen gas react to form water vapor and carbon dioxide gas. What volume of carbon dioxide would be produced by this reaction if 6.47 L of oxygen were consumed? Also, be sure your answer has a unit symbol, and is rounded to 3 significant digits.

When methane (CH4CH4) burns, it reacts with oxygen gas to produce carbon dioxide and water. The unbalanced equation for this reaction is CH4(g)+O2(g)→CO2(g)+H2O(g)CH4(g)+O2(g)→CO2(g)+H2O(g) This type of reaction is referred to as a complete combustion reaction. Part A What mass of carbon dioxide is produced from the complete combustion of 1.80×10−3 gg of methane? Part B What mass of water is produced from the complete combustion of 1.80×10−3 gg of methane? Part C What mass of oxygen is needed for the...

Q11. Which of the following reason can explain that carbon dioxide is considered as an important factor for climate change? A.carbon dioxide absorbs water vapor B.carbon dioxide react with water vapor C.carbon dioxide absorbs infrared radiation D.carbon dioxide can be broken down as carbon atoms and oxygen molecules by ultraviolet radiation, then the carbon burns with the oxygen. - Q12. Which of the following statements is NOT true? A.Atmosphere is NOT well-mixed from bottom to top. B.Atmospheric pressure decreases with...
