Answer:
CO₂
Explanation:
Carbon dioxide is a covalent compound. Two double bonds are formed between two oxygen atoms and one carbon atom. O=C=O
The covalent bond between them are polar.
Covalent bond:
It is formed by the sharing of electron pair between bonded atoms.
The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.
For example:
In carbondioxide the electronegativity of oxygen is 3.44 and carbon is 2.55. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and carbon becomes partial positive. The electronegativity difference is 0.89 that's why it is polar covalent bond.
Answer:
I answer this question I think I said the second one
<span>The phosphorus cycle is different compared to the water,carbon, and nitrogen cycle because it can not be found in the gas state. Phosphorus is only found in land, water, and sediment. The phosphorus cycle is a bio-geochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere. The other cycles is the process by which it is converted between its various chemical form. Phosphorus has small particles that only sometime go up into the atmosphere and contribute to acid rain but other than that phosphorus stays in and on land, sea, and sediment.(:
Good luck!</span>
Yes if we use the resource up before it can renew itself then it could be used up and be depleted or near depletion. The resource has to have time to come back and if we use it up to fast then the resource can not take the time it needs to come back.
Answer:
Nuclear properties
Naturally occurring beryllium, save for slight contamination by the cosmogenic radioisotopes, is isotopically pure beryllium-9, which has a nuclear spin of 3/2.Beryllium is alloyed with copper or nickel to make springs, gyroscopes, electrical contacts, spot-welding electrodes and non-sparking tools, according to the Royal Society of Chemistry. Other beryllium alloys are used in high-speed aircrafts and missiles, as well as spacecraft and communication satellites.
