thunderstorms and heavy rain

Explanation:

The weather in a region with an incoming air mass made up of moist air is predominantly that of thunderstorms and heavy rain.

Moist air brings in rainfall and thunderstorms. They are peculiar and predominant in tropical regions of the world .

A moist air is an air mass that is moisture laden or full of water vapor.
They are usually formed where evaporation of water vapor from sea water is very high.
The evaporated water is warmer and lighter than the surrounding air.
By virtue of this, it moves inland and condenses to form massive rainfall accompanied by thunderstorm.

Can someone help me? It needs to have a diagram that has arrows.

Answer: The enthalpy change for formation of butane is -125 kJ/mol

Explanation:

The balanced chemical reaction is,

$C_4H_{10}(g)+\frac{13}{2}O_2(g)\rightarrow 4CO_2(g)+5H_2O(l)$

The expression for enthalpy change is,

$\Delta H=[n\times H_f{products}]-[n\times H_f{reactants}]$

Putting the values we get :

$\Delta H=[4\times H_f_{CO_2}+5\times H_f_{H_2O}]-[1\times H_f_{C_4H_{10}}+\frac{13}{2}\times H_f_{O_2}]$

$-2877=[(4\times -393)+(5\times -286)]-[1\times H_f_{C_4H_{10}}+\frac{13}{2}\times 0]$

$H_f_{C_4H_{10}=-125kJ/mol$

Thus enthalpy change for formation of butane is -125 kJ/mol
