Expert Solution

Part A)

When asteroid parts containing Carbon enter in to the earth's atmosphere, due to the presence of oxygen gas in the earth's atmosphere Carabon atoms react with oxygens atoms Carbon monoxide is formed first then Carbon dioxide is formed. The chemical reaction can be written as follows.

2 CO (g) + O2 (g) ? 2 CO2 (g)

Part B)

Carbon atom is a tetravallent atom so it has 4 vallence electrons. Each Carbon atom has oxidation state of 4+ Where as each Oxygen has oxidation state of 2- . So each Carbon atom forms a double bond with two oxygen atoms. Hence the chemical bonding between C and O atoms is covallent bond.

O = C = O

Part C)

The formation of CO2 is due to combustion of Carbon in excess oxygen. Hence the reaction is Combustion.

The composition of the earth's atmosphere may have changed over time. To try to discover the nature of the atmosphere long ago, we can examine the gas in bubbles inside ancient amber. Amber is tree resin that has hardened and been trapped in rocks. The gas in bubbles within amber should be a sample of the atmosphere at the time the amber was formed. Measurements on specimens of amber from the late Cretaceous era (75 to 95 million years ago)...

When organic fuels like propane (C3H8) burn completely with oxygen from the air, all the carbon atoms in the propane molecules make carbon dioxide (CO2) molecules and all the hydrogen atoms make water (H2O) molecules. C3H8 + 5 O2  3 CO2 + 4 H2O. This is a balanced reaction because there are 3 carbon atoms on each side of the arrow, 8 hydrogen atoms on each side of the arrow, and 10 oxygen atoms on each side (5 O2...
