Final Answer:
The weight % of Carbon in crude oil is generally more than 75%. Thus the correct option is D. More than 75%.
Step-by-step explanation:
Crude oil is a complex mixture of hydrocarbons, consisting primarily of carbon and hydrogen atoms. The chemical composition of crude oil can vary, but on average, carbon content exceeds 75%. This is because hydrocarbons, the fundamental building blocks of crude oil, are composed mainly of carbon atoms bonded to hydrogen atoms. The high carbon content is a result of the organic origin of crude oil, as it is formed from the remains of ancient marine organisms.
Moreover, the composition of crude oil can be analyzed through various methods, such as chromatography and spectroscopy. These techniques reveal the abundance of different elements within the crude oil, allowing scientists to determine the weight percentage of carbon accurately. The carbon content is crucial in understanding the energy potential and chemical properties of crude oil, influencing its combustion characteristics and industrial applications.
In summary, the weight % of carbon in crude oil is indeed more than 75%, making option (d) the correct choice. This high carbon content underscores the significance of crude oil as a carbon-rich resource in the global energy landscape, playing a pivotal role in various industries and serving as a primary feedstock for the production of fuels and petrochemicals.
Thus the correct option is D. More than 75%.
