The cons of using dispersants are their toxicity to marine environment. Dispersants are also less effective on heavy oils. Dispersants result to oil sinking into the water column from the surface hence this spreads the effect of pollution. Advantages of dispersants are they reduce oil pollution impact onshore and also reduce its risks to marine animals with furs or plumage.


Advantages of using bacteria are that they consume the oil until no residue is left. The bacteria are not toxic like dispersants and reduce in number when the oil pollutant is degraded. Cons of bacteria are that they are unable to break down particular hydrocarbons; they are slow in degrading the oil and are only particularly effective in finishing off oil residue rather than cleaning up large oil spills.

Serggg [28]

Dr. Haxton says the O-O bond is polar and the C-C bond is nonpolar. A good student would say ...

a.No, both bonds are highly polar.

b.Yes. O attracts electrons more strongly than C.

c.Right! O is electronegative, so O2 is polar.

d.Wrong again, Ralph. Both bonds are nonpolar. When two atoms of the same kind form a covalent bond, they share electrons equally because their electronegativity is the same.

e.No way. C is more electronegative than O.

Answer: d.Wrong again, Ralph. Both bonds are nonpolar. When two atoms of the same kind form a covalent bond, they share electrons equally because their electronegativity is the same.

Explanation:

Often when O and H are present in the substance at (opposite) ends (of the electronegativity scale), the polarity observed is very large, we can safely say the substance have a polar bond in it.

Energy enters a food chain as heat energy and leaves it as light energy.
hjlf

Answer:

The statement that says "Energy enters a food chain as heat energy and leaves it as light energy" is false.

Explanation:

The energy that enters the food chains, first of all, is light energy from the sun. This energy is assimilated by plants to convert it into chemical energy, through  photosynthesis.

When energy flows from producers, plants, to consumers and decomposers, a great amount of <u>energy is lost, in the form of </u><u>heat energy</u>, due to the metabolism of living beings. Additionally, the second law of thermodynamics states that when energy passes from one form to another it leads to disorder in the system, which would also explain the loss of energy.

The true statement is "Energy enters a food chain as <u>light energy</u> and leaves it as <u>heath energy"</u>.
