One.

In organic chemistry, an electrophile<span> is a reagent attracted to electrons.</span>Electrophiles<span> are positively charged or neutral species having vacant orbitals that are attracted to an electron rich centre. It participates in a chemical reaction by accepting an electron pair in order to bond to a nucleophile.
</span>
Carbon attached to O is electrophylic.

The electronegativity is 2.1 for h and 1.9 for pb. based on these electronegativities pbh4 would be expected to
Sedbober [7]
PbH4 will be formed as a result of a polar covalent bond between the H and the Pb.

Since H is more electronegative than the Pb, it is, thus, expected that the H would be able to pull the electron charge towards itself. This will result in the H being negative.

Based on this:
PbH4 would be expected to <span>have polar covalent bonds with a partial negative charges on the H atoms. </span>

Explain how you could use the solubility of a substance to make a saturated solution.
dlinn [17]
A saturated solution is prepared by continuously adding solute to the solution until a stage is reached where the solute appears as a solid precipitate or as crystals to form a highly saturated solution. Consider the process of adding table sugar to a container of water.

Make notes on why did the levels of carbon dioxide in the atmosphere decrease?​
kykrilka [37]

Answer:

Carbon dioxide is a very soluble gas. It dissolves readily in water. As the oceans formed, carbon dioxide dissolved to form soluble carbonate compounds so its amount in the atmosphere decreased. Carbonate compounds were then precipitated as sedimentary rocks, eg limestone.

Uptake by living organisms

Carbon dioxide was also absorbed from the oceans into photosynthetic algae and plants. Many of these organisms, and the simple organisms in the food chains that they supported were turned into fossil fuels, eg crude oil, coal and natural gas, which all contain carbon.

Coal is a fossil fuel which was formed from trees which were in dense forests in low-lying wetland areas. Flooding caused the wood from these forests to be buried in a way that prevented oxidation taking place. Compression and heating over millions of years turned the wood into coal.

Crude oil and natural gas were formed from simple plants and tiny animals which were living in oceans and lakes. These small organisms died and their remains sank to the bottom where they were buried under sediments. The lack of oxygen prevented oxidation from occurring.

Over millions of years, heat and pressure turned the remains of the organisms into crude oil and natural gas. Natural gas contains the smallest molecules and is often found on top of crude oil, trapped under sedimentary rock.

The presence of a large population of _____________ indicates water depleted of oxygen and a high level of organic pollution.
blondinia [14]

The presence of a large population of sludgeworms indicates water depleted of oxygen and a high level of organic pollution.

The sludgeworms Tubifex is harvested and sold as tropical fish food since it is common near sewer outlets and serves as a sign of water or organic pollution. Polychaetes are crucial in rearranging the silt on the ocean floor.

Organic contamination happens when too much organic material, such sewage or manure, gets into the water.

There will be more decomposers and sludgeworms in a pond as the organic content accumulates. These decomposers and sludgeworms develop quickly and consume a lot of oxygen as they do so.

Hence, Sludgeworms are a sign of an abundance of oxygen-depleted water and significant levels of organic pollutants.
