The formation of CsCl from Cs(s) and Cl2 (g) involves the following steps:
scoray [572]

Explanation:

1) Cs(s)\rightarrow Cs(g)

Energy will be absorbed by the Cs(s) to get converted into Cs(g). In order to break the strong association of particles present in solid to convert it into gaseous state energy will be needed. So, energy will be absorbed by the Cs solid in this reaction.

2) \frac{1}{2}Cl_2(g)\rightarrow Cl(g)

Energy will be absorbed by Cl_2 gas in order to break bond between two Cl atoms to form isolated(alone) single chlorine atom.So, the energy will be absorbed by the chlorine gas molecule in this reaction.

3) Cs(g)\rightarrow Cs^+(g)+e^-

Energy will be absorbed by the Cs(g) to get converted into Cs^+(g) cation. In order to remove an electron from the outer most shell of Cs atom energy will be required by Cs atom, So, energy will be absorbed in this reaction.

4) Cl(g)+e^-\rightarrow Cl^-(g)

Energy will get release in formation of Cl^- anion from Cl atom in gaseous state. Chlorine atom need one electron to attain noble gas configuration. So, when an electron is added to the outer most shell of chlorine it attains stability of fully filled outermost shell by which it releases energy on addition of an electron.

5) Cs^+(g)+Cl^-(g)\rightarrow CsCl(s)

Energy will get release on formation of CsCl(s) fromCs^+ cation and Cl^- anion. since both are oppositely charged ion and due to strong electrostatic interaction will get converted into stable molecule of CsCl (s) with release in an energy.

Using your understanding of environmental science, make a hypothesis about how these six vehicles compare with regard to total l
gtnhenbr [62]

Answer:

Answer is option (d) (lowest to highest)

We have to rank the six vehicles according to the CO2 emission causing an impact on global warming. We know that burning of coal has the highest emission of all fossil fuel so EV powered by electricity from it will be the highest impact on global warming with highest CO2 emission, next is burning of gasoline, but the CO2 emission can be varied by the process of the burning in engines obviously a high-efficiency burning will have less impact than a regular standard engine. So, after ICEV standard will have high CO2 emission than the ICEV (high efficiency), now the next will be EV which is having its electricity supplied by a mix of resources, the production involves both fossil and non-fossil fuel which make this vehicle more environmentally friendly than the full fossil fuel-based. The ICEV with less driving has the second least emission because you are not burning the fuel like other vehicles because of not driving the vehicle. In the last will be the EV having powered by electricity of wind it will be the least emission almost zero because it using wind power to generate electricity. Hence arrangement comes like this, EV(wind), ICEV(less driving), EV (mix of sources), ICEV (high-efficiency), standard ICEV, EV (coal) from lowest to highest CO2 emission.
