The answer is B hope this is right
Answer:
Explanation:
Thermal stability is the tendency to not break down when exposed to heat. A more negative enthalpy of formation will correlate with more stable products. Therefore, the more negative the enthalpy of formation is for a substance, the greater its thermal stability.

Answer:
Double displacement reaction
Explanation:
Given expression:
KOH + AlCl₃ → Al(OH)₃ + KCl
The reaction shown above is a double displacement reaction or double decomposition or double replacement reaction. This type of reaction involves an actual exchange of partners to form new compounds.
For example:
AB + CD → AD + CB
Such reactions are driving by one of the following factors:
- formation of an insoluble compound
- formation of water or any other non-ionizing compound
- liberation of a gaseous product
