Answer 1: Option(B) Nitrogen

Explanation:

The earth's atmosphere comprises of different gases which are Nitrogen(78%), plenty of Oxygen(21%), argon(0.9%) and remaining are the methane, gaseous oxides etc. So Nitrogen is present in largest quantity in the earth's atmosphere.

Answer 2: Option(D) Ozone

Explanation:

The Stratosphere is the second lowest layer of the earth. It contains the ozone which absorbs the UV rays coming form the sun because of which there is a rise in temperature than other layers.

Answer 3: Option(A) Heat from the earths core

Explanation:

The heat energy coming from the Sun heats the earth non-uniformly that results in the hot and cold area on the earth causes low and high air pressure.The Sun heats the earth core. When there is a hot weather the land near the sea becomes hot in comparison with the sea results in the hot wind flow from the sea.

Why are scientists worried that climate change will cause these toxic algae blooms to become more frequent?
ipn [44]

Answer: Eutrophication is the enhancement of the growth of algae in the water body.

Explanation:

The scientists are worried for the climate change as if the climate changed to prolonged rainy then the frequent raining can remove toxic chemicals from the agricultural sites, landfills, industries, and from other locations and deposit them to the water body (river, lakes, ponds, and others). The deposition of the salts of nitrogen, phosphorus, and sulfur promotes the growth of algae in the water body. This leads to reduction in the concentration of oxygen in the water body. This is called eutrophication. The lack of oxygen can lead to mortality of aquatic animals.

C10H22 &gt; C8H18+C2H4 if only ethane can be sold what is the atom econmy of this process
insens350 [35]

Answer:

The atom economy of ethane in this process is 19.72 %.

What is atom economy?

The conversion efficiency of a chemical reaction in terms of all the atoms involved and the desired products produced is known as atom economy (atom efficiency/percentage).

Explanation:

C₁₀H₂₂ → C₈H₁₈ + C₂H₄

Molecular weight of C₁₀H₂₂ = 142.28

Molecular weight of C₈H₁₈ = 114.228
Molecular weight of C₂H₄ = 28.053

% Atom economy =     \frac {Molecular weight of C2H4} {Molecular weight of C10H22}

                             = \frac{28.053}{142.28}*100

                             = 19.716 %

                             ≈ 19.72 %
