Answer:
See the answer below
Explanation:
Natural gas from different countries has a different percentage of hydrocarbons because they are formed from different biomass of organisms.
Natural gas is formed from decomposed organic matter that has been deposited millions of years ago. Layers of decomposing plants and animal matters buried deep in the ground experience intense heat and pressure and are eventually transformed after millions of years.
Different countries have different diversity of organisms. Hence, the organic matter that eventually transforms into natural gas for each country also differ. The implication is that the natural gas that would be formed in each country would be different. This is why natural gas from different countries may have different percentages of hydrocarbons.
