Please help me ASAP I’ll mark

- Oil Energy is a Major Source of Pollution and Damage Made to the Environment Every Year.

- Oil Like the Other Fossil Fuels Is A Finite Resource.

- Emissions Produced by Oil Causes Acid Rain

-Plastic is One of the Products Obtained Through Oil Refining.

- Working in the Oil Sector Can Be a Dangerous Activity.

hope this is good enough :)

Pros: Oil can easily be transported by a network of pipelines.

Oil-fired power stations can, in theory, be built almost anywhere.

The oil is burned to heat water and produce steam. This steam propels the blades of a turbine. This is attached to a generator, which produces electricity.

Cons: Oil is a non-renewable source of energy. This means that one day we will probably run out of crude oil.

Burning oil produces carbon dioxide gas. This is a greenhouse gas that contributes towards climate change.

Burning oil can pollute the air.

Much of our oil has to be imported and it is becoming more and more expensive as reserves reduce and imports increase.

Producing electricity from crude oil is expensive compared to other fossil fuels such as coal or gas.

Explanation:

it would be a gas formation

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
