A pure substance is a material made of only one type of particle.

What is pure substance?

A substance that has fixed in chemical composition throughout is called a pure substance such as water, air and nitrogen. The  pure substance doesn't have to be of a single element or compound. A pure substance consists only of one element for the or one compound. a mixture consists of two or more different substances, not chemically joined together.

Examples of pure substance include tin, sulfur, diamond, water, pure sugar (sucrose), table salt (sodium chloride) and the  baking soda (sodium bicarbonate). Crystals, in general, are pure substances.

Elements are the pure substances that cannot be broken down into simpler substances by any physical or chemical means we know  as they have only one kind of atom at the  entire composition. Thus when gold is tjr broken down it still remains gold and hence is considered a pure substance is and an element.

40 POINTS PUT A GOOD ANSWER
Andreyy89

Answer:

<u>B</u> What role do animals have in the carbon cycle?

Group of answer choices

use water and release oxygen

<u>use sugar and release carbon</u>

use carbon and release oxygen

use carbon and release nitrogen

<u>D, E</u> Select TWO statements that describe what the scientists will observe in the ecosystem after fossil fuels have been extracted and burned.

Group of answer choices

There is more available space for carbon to become fossil fuels.

There is less carbon in storage.

There will be less carbon in the water.

<u>There is more carbon in the atmosphere.</u>

<u>There will be more carbon respired by organisms.</u>

There will be less carbon released through decomposition.

Explanation:

Animals obtain energy through sugar from the food they eat and release carbon into the air through respiration. Therefore, they partake in the carbon cycle by using sugar and releasing energy.

As far as the second question, when fossil fuels are burned, the carbon contained within them is released into the atmosphere in the form of carbon dioxide. So, there will obviously be a greater amount in the atmosphere.

I would like to apologise in advance if either of my option choices were incorrect.
