In which thermochemical equations would the ΔH be considered a heat of solution? 2NaHCO3(s)→Na2CO3 (s) + H2O (g) + CO2 (g), ΔH = –129 kJ C6H6(s)→C6H6(l), ΔH=+9.87 kJ NH4NO3(s)→NH4+(aq)+NO3–(aq), ΔH=+25.7 kJ/mol 2C8H18(l)+25O2(g)→16CO2(g)+18H2O(l) , ΔH =–5,471 kJ/mol

NH4NO3 (s) --> NH4+ (aq) + NO3- (aq) H = +25.7 kJ/mol

Explanation:

Step 1: Data given

2NaHCO3(s) → Na2CO3 (s) + H2O (g) + CO2 (g) ΔH = –129 kJ

C6H6(s) → C6H6(l) ΔH=+9.87 kJ

NH4NO3(s )→ NH4+(aq) + NO3–(aq) ΔH=+25.7 kJ/mol

2C8H18(l) + 25O2(g) → 16CO2(g) + 18H2O(l) ΔH =–5,471 kJ/mol

Step 2:

2NaHCO3(s) → Na2CO3 (s) + H2O (g) + CO2 (g)  H = -129 kJ:

This is the decomposition reaction of NaHCO3.

NaHCO3 will break down and form Na2CO3, H2O and CO2

⇒ the heat here is heat of decomposition

C6H6 (s) --> C6H6 (l), H = +9.87 kJ  

In this reaction we'll not form a new product. Benzene will change phase. From its solid form to liquid benzene.

⇒ the heat here is heat of fusion

NH4NO3 (s) --> NH4+ (aq) + NO3- (aq) H = +25.7 kJ/mol  

When solid NH4NO3 is dossolved in water. it will dissociate in ammonium ion (NH4+) and nitrate ion (NO3-).

This reaction shows a solid dissolving in water and therefore the H represents the heat of solution.

⇒ The heat here is heat of solution

2C8H18 (l) + 25O2 (g) --> 16CO2 (g) + 18H2O (l), H = -5,471 kJ/mol: this is a combustion reaction

This is the combustion reaction of octane. CO2 and H2O will be produced.

⇒  The heat here is heat of combustion.

when atmosphere interacts with biosphere they focuses on on the sources and sinks of green house gases (ghgs) air pollutants, particular matters, water and energy between the earth's surface and the atmosphere. the biosphere affects the climate. the atmosphere and biosphere are in constant interaction with each other, and all living things rely on gases in the atmosphere for life. organisms such as animals take in oxygen gas form the atmosphere to use in every cell of their body for smooth functioning of daily routine exercises.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
