PLEASE ANSWER THESE 2 QUESTIONS!!!100 POINTS!!!!!PLS HURRRY!!!!!!!!!!!!!!!!!!!!!!!!!!!

1. A state is looking to adopt new management protocols for a metal resource within its borders. Two proposals are being considered. Determine whether each proposal will have a positive or negative impact on the environment and sustainability of the metal resource.

Proposal 1: Offer free recycling services for the metal.

Proposal 2: Burn waste and recover the metal from the ash.

Proposal 1 will have a

Positive or Negative

impact on the environment. It will have a

Positive or negative

impact on the sustainability of the metal resource.

Proposal 2 will have a

Negative or Positive

impact on the environment. It will have a

Negative or Positive

impact on the sustainability of the metal resource.

2.Drag the appropriate terms into the table to answer the questions. Each term may be used more than once.(2 points)

I picture below!

1) Proposal 1: positive impact on the environment / positive impact on the sustainability. Proposal 2: negative impact on the environment / positive impact on the sustainability. 2) alumina, alumina, aluminum, alumina, aluminum.

What are the differences between alumina and aluminium?

Aluminum is a metal with a grey or silvery-like appearance. It turns into a chemical element.

Alumina is a white-colored substance of robust base, which forms part of rocks and minerals.

Aluminum exists by itself in nature.

Alumina only exists when it gets mixed with oxygen, composing the aluminum oxide.

Aluminum is an electrical conductor, while alumina is an electrical insulator.

Aluminum is highly reactive and acts with hydrogen and oxygen to produce different compounds.

Alumina does not properly act with other elements.

Question 1)

⇒ Proposal 1: Offer free recycling services for the metal.

This proposal will have a positive impact on the environment and a positive impact on the sustainability of the metal resource.

This is because

it will remove metals from wastes, clean the environment and avoid a higher contamination, and

it will reuse and recycle the metal, which will provide a longer useful life for the material.

⇒ Proposal 2: Burn waste and recover the metal from the ash.

This proposal will have a negative impact on the environment and a positive impact on the sustainability of the metal resource.

This is because

it will pollute the air by burning waste. It will cause the emission of nocive gasses to the atmosphere.

it will recover the metal to be reused and recycled, increasing its useful life.

Question 2)

Alumina ⇒ also known as aluminum oxide

Alumina ⇒ white powder produced from the refinement of bauxite

Aluminum metal ⇒ a good conductor of electricity

Alumina ⇒ an electrical insulator

Aluminum metal ⇒ a silvery white solid

Answer:

one.

Why is bauxite the most common ore that aluminum is extracted from? Select the two correct answers.

It is located near the surface and can be easily strip mined.

It is the most abundant ore of aluminum.

2.

Drag the appropriate terms into the table to answer the questions. Each term may be used more than once

also known as aluminum oxide, white powder produced from the refinement of bauxite, an electrical insulator [all three is alumina]

an electrical insulator, a good conductor of electricity [both are aluminum metal]

3.

According to the USGS, how much total copper was contained in world reserves as of 2018?

790 millions tons

4.

Select the correct answer from the list.

A state is looking to adopt new management protocols for a metal resource within its borders. Two proposals are being considered. Determine whether each proposal will have a positive or negative impact on the environment and sustainability of the metal resource.

Proposal 1: Offer free recycling services for the metal.
