Question

as trash in the landfill decomposes, a greenhouse gas is produced and leaks from the landfill. we install gas detection units at various locations around the landfill to detect this gas as it is released. which gas is released? argon methane

Explanation:

When trash decomposes in a landfill, it undergoes anaerobic digestion (decomposition without oxygen). Methane (\(CH_4\)) is a major greenhouse gas produced during this process. Argon (\(Ar\)) is an inert gas and not produced by landfill decomposition.

Answer:

Methane
