Explanation:
When water reacts with formic acid, The following equilibrium is set up;
HCOOH(aq) + H20(l) ⇄ HCOO-(aq) + H30+(aq)
This is because, the water abstracts a proton from formic acid to form its conjugate base, formate ion.
At equilibrium, the forward is favored.
Answer :
An egg cooking is an endothermic reaction.
A candle burning and Plaster & water combining and becoming warm are exothermic reaction.
Salt being added to water, with no change in temperature neither endothermic nor exothermic reaction.
Explanation :
- Endothermic reaction : It is a type of reaction in which energy is absorbed in the form of heat from the surroundings.
- Exothermic reaction : It is a type of reaction in which energy is released in the form of heat from the system.
An egg cooking : In this process, the energy is absorbed in the form of heat.
A candle burning and Plaster & water combining and becoming warm : In both the process, the energy is released in the form of heat.
Salt being added to water, with no change in temperature : In this process, neither energy released nor absorbed.
B ice melting hope it helps
