Question

Can someone help with what I would do with this sort of question

Answer 1

• Reaction:

`\begin{gathered} 2C\text{ + 3H}_2\text{ + }(1)/(2)O_2\text{ }\rightarrow\text{ CH}_3CH_2OH \\ \Delta H=\text{ Enthalpy change of formation} \end{gathered}`

• Reaction:

`\begin{gathered} (NH_4)_2SO_4\text{ }\rightarrow\text{ 2NH}_4^+\text{ + SO}_4^(2-) \\ \Delta H=\text{ Enthalpy change of solution} \end{gathered}`

• Reaction:

`\begin{gathered} Na_((g))^+\text{ }\rightarrow\text{ Na}_((aq))^+ \\ \Delta H=\text{ Enthalpy change of hydration} \end{gathered}`

• Reaction:

`\begin{gathered} C\text{ + O}_2\text{ }\rightarrow\text{ CO}_2 \\ \Delta H=\text{ Enthalpy change of combustion} \end{gathered}`

• Reaction:

`\begin{gathered} Na_((s))\text{ }\rightarrow\text{ Na}_((g)) \\ \Delta H=\text{ Enthalpy change of atomisation} \end{gathered}`

• Reaction:

`\begin{gathered} Na_((g))\text{ }\rightarrow\text{ Na}^+_((g))\text{ + e}^- \\ \Delta H=\text{ Enthalpy change of ionisation} \end{gathered}`

• Reaction:

`\begin{gathered} F_((g))\text{ + e}^-\text{ }\rightarrow F_((g))^- \\ \Delta H=\text{ Enthalpy change for electron affinity} \end{gathered}`

Step-by-step explanation:

• Enthalpy change of ,combustion,: is the enthalpy involved in the process of in which a compound burns in the presence of oxygen (or air).

,

• Enthalpy change of ,formation,: this enthalpy change is the one involved when 2 or more reactants combine to form a product.

,

• Enthalpy change of ,solution,: is the energy present in the dissolution of a substance in a solvent.

,

• Enthalpy change of ,hydration,: it is the energy that intervenes when a substance in gaseous atate becomes part of the aqueous solution.

,

• Enthalpy change of ,atomisation,: this is necessary to form gaseous atoms from the element under standard conditions.

,

• Enthalpy change of ,ionisation,: is the energy involved when an ion is formed.

,

• Enthalpy change for ,electron affinity,: is the energy released when a neutral gaseous atom takes on an electron and forms a negative ion.
