Answer:

D

Explanation:

We must study the reaction pictured in the question closely before we begin to attempt to answer the question.

Now, the reaction is a free radical reaction. This implies that only one electron is transferred. The transfer of one electron is shown using a half arrow rather than a full arrow. The both species are radicals (odd electron species) and contribute one electron each.

Hence we must show electron movements in both species using a half arrow.

One major cause of flood is
Ber [7]

Answer:

Localized flooding may be caused or exacerbated by drainage obstructions such as landslides, ice, debris, or beaver dams. Slow-rising floods most commonly occur in large rivers with large catchment areas. The increase in flow may be the result of sustained rainfall, rapid snow melt, monsoons, or tropical cyclones.

g Gaseous methane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Suppose 0.96 g of methane
galben [10]

Answer: 2.64 g of carbon dioxide that could be produced by the chemical reaction.

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of} CH_4=\frac{0.96g}{16g/mol}=0.06moles

\text{Moles of} O_2=\frac{6.37}{32}=0.20moles

CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(g)

According to stoichiometry :

1 mole of CH_4 require = 2 moles of O_2

Thus 0.06 moles of CH_4 will require=\frac{2}{1}\times 0.06=0.12moles  of O_2

Thus CH_4 is the limiting reagent as it limits the formation of product and O_2 is the excess reagent.

As 1 moles of CH_4 give = 1 mole of CO_2

Thus 0.06 moles of CH_4 give =\frac{1}{1}\times 0.06=0.06moles  of CO_2

Mass of CO_2=moles\times {\text {Molar mass}}=0.06moles\times 44g/mol=2.64g

Thus 2.64 g of carbon dioxide that could be produced by the chemical reaction.

Involves combining of nuclei:
bogdanovich [222]

Explanation:

Involves combining of nuclei:  Nuclear fusion

Nuclear fusion is a radioactive reaction  in which small atomic nuclei combines into larger ones with the release of a large amount of energy. The energy released is used to furnish a series of chain reactions.

Produces dangerous radioactive waste:  Nuclear fission

Nuclear fission is used in powering most nuclear power plants. The products of these reactions are radioactive in nature. They are very dangerous to human health and the environment at large.

Have high activation energies:  Nuclear fusion

The activation energy is the energy barrier that must be overcome before a reaction starts. Nuclear fusion reactions require very high amount of energy input to overcome the activation needed to start the reaction.

Releases large amounts of energy:  Nuclear reactions

Both nuclear fusion and fission releases large amount of energy.

Occurs in the stars:  Nuclear fusion

Nuclear fusion occurs in stars and they involve the combination of atomic nuclei to form larger ones.

Drives chemical plants: Nuclear fission

Chemical plants uses electricity and nuclear power plants can produce electricity through nuclear fission.
