The option that does not contain carbon is ozone.
Diamond and graphite are made of carbon almost entirely, and alcohols are organic compounds so they do contain it.
Ozone has the chemical formula of O3, so you see there is no carbon involved.
Answer:
- Blank 1: <u>million of years</u>
- Blank 2: <u>compression</u>
- Blank 3: <u>decomposition</u>
Explanation:
<em>Fossil fuels</em> are mixtures of substances that can be burne to obtain energy like coal, petroleum and natural gas.
They are formed by <em>organic matter,</em> mainly carbon and hydrogen, along with other elements.
The theory with the most consensus on the formation of <em>fossil fuels</em> is that they formed after <em>organic matter</em>, plants and animals, died and were buried under a huge mass of sediments.
The huge pressures, in the absence of oxygen, yield the decomposition of the organic matter to form the fossil fuels.
Due to the fossil fuels require million of years to be formed they are considered nonrenewable energy resources, as they cannot possible be formed in a reasonable time on human life scale.
Answer:
11.442E23molecules
Explanation:
Given data:
Number of moles of water = 1.9 mol
Number of molecules of water = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
In 1.9 moles:
1.9 mol × 6.022 × 10²³ molecules / 1 mol
11.442 × 10²³ molecules
In e notation:
11.442E23 molecules
The answer is C multiple alleles
