Easy answer you could have come up with by yourself I think.

Crude oil, means oil straight from the ground and not refined yet.

Heavy metals means not light metals. So not iron or sodium but Lead and other heavy stuff.

Since oil comes from the ground and metals are mined from the ground, it makes sense that they could be found together.

So if the teacher wants a different answer he should have said "how is crude oil formed" or something like that.

What is the difference between heavy crude oil and light crude oil?

Heavy crude oil has a higher density and viscosity compared to light crude oil. Heavy crude oil also contains more impurities like sulfur and metals, which makes it more difficult and expensive to refine. Light crude oil is easier to extract, transport, and refine, making it more valuable in the market.


Impurities found in crude oil?

Impurities found in crude oil include sulfur compounds, nitrogen compounds, heavy metals, salt, and sediment. These impurities can affect the quality of the oil and must be removed through various refining processes to meet product specifications for use as fuels or petrochemical feedstocks.


Why is heavy crude oil cheaper then light crude oil?

Heavy crude oil is typically cheaper than light crude oil because it requires more processing to remove impurities and make it usable. This additional processing increases the overall cost of production, which is then reflected in the price of heavy crude oil compared to light crude oil. Additionally, heavy crude oil tends to have higher sulphur content, which can further increase the cost of refining.


What things are made from crude oil?

Crude oil is mixture of many compounds. Most of the compounds are composed of hydrogen and carbon, so they are called hydrocarbons. Oxygen, nitrogen, sulfur and various trace metals also can be found in crude oil. When there is significant concentrations of sulfur, the crude is considered sour crude. See links.
