Methane (CH4) undergoes combustion. Which products form? A. C and H20
B. CO2 and H20
O C. CO2 and H2
D. CO2, H20, and O2

carbon dioxide (CO2) and water (H2O).

Explanation:

When methane burns in the air it has a blue flame. In sufficient amounts of oxygen, methane burns to give off carbon dioxide (CO2) and water (H2O). When it undergoes combustion it produces a great amount of heat, which makes it very useful as a fuel source. Methane is a very effective greenhouse gas.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
