Concept explainers
Interpretation: The process of formation of aurora borealis and aurora Australis should be determined.
Concept Introduction:
Atmosphere: The atmosphere is defined as air that is layer of gases which surrounds the earth due to gravity of earth.
The earth atmosphere consists of layers such as thermosphere, mesosphere, stratosphere and troposphere depending on the temperature and its composition.
The different regions of atmosphere and their description are as follows:
Thermosphere:
It is the top most layers in atmosphere which has high temperature than all other layers present in atmosphere. The high temperature is due to the heat released by the reactions like continuous attack of
Mesosphere:
It is layer next to thermosphere that is the layer below the thermosphere. The increasing temperature for this layer with respect to decreasing height is due to the presence of less concentration of ozone and other gases in it.
Stratosphere:
It is found below the mesosphere layer in which the concentration of ozone and other gases are high. The increasing temperature for this layer with respect to increasing height is due to the presence of high concentration of ozone and other gases in it.
Troposphere:
The layer is below stratosphere layer and it is closest to the earth surface. It is the thinnest place which is responsible for all weather conditions since it contains almost all amounts of water vapor with it.
Aurora borealis: They are celestial lights found in northern hemisphere.
Aurora Australis: They are same as aurora borealis but found in southern hemisphere.
To explain: The process for formation of aurora borealis and aurora Australis.

- For the single step reaction: A + B → 2C + 25 kJ If the activation energy for this reaction is 35.8 kJ, sketch an energy vs. reaction coordinate diagram for this reaction. Be sure to label the following on your diagram: each of the axes, reactant compounds and product compounds, enthalpy of reaction, activation energy of the forward reaction with the correct value, activation energy of the backwards reaction with the correct value and the transition state. In the same sketch you drew, after the addition of a homogeneous catalyst, show how it would change the graph. Label any new line "catalyst" and label any new activation energy.arrow_forwardHow many grams of C are combined with 3.75 ✕ 1023 atoms of H in the compound C5H12?arrow_forwarde. f.
