Question

Answer 1

Answer:

1. Over half of the carbon monoxide in the atmosphere comes from human activities including
2. motor traffic,
3. other combustion of fossil fuels, and
4. slash and burn agriculture.

• Additional anthropogenic sources include the burning of wood,
• savannah lands, and
• the oxidation of hydrocarbons including methane

Answer 2

Answer:

Carbon has 4 valence electrons in its valence shell and Oxygen has 6 valence electrons its its outermost shell.Oxygen atom needs 2 electrons to obtain its octet.And hence,Carbon atom shares its  two valence electrons to form carbon-monoxide and share its 4 valence electrons to form carbon-dioxide.

Explanation:

C4+O6=O8+C2 (octet of oxygen)=CO

C4 +O6=08=CO2
