Methane: Most Abundant Combustible Natural Gas

Natural gas is a fossil fuel composed primarily of hydrocarbons. The question asks to identify the most abundant combustible component within natural gas.

Component Analysis

• Natural gas is predominantly composed of methane ($CH_4$). Methane typically makes up 70% to 90% of natural gas.
• Propane ($C_3H_8$), ethane ($C_2H_6$), and butane ($C_4H_{10}$) are also hydrocarbons found in natural gas, but in much smaller quantities compared to methane.
• Methane is a highly combustible gas, serving as the primary fuel source in natural gas.

Conclusion

Due to its high percentage composition in natural gas reserves and its combustible nature, methane is the most abundant combustible natural gas.
