Answer: potential.
Chemical energy is the energy provided by a chemical reaction.
Kinetic energy is the energy due to the speed.
Potential energy is the energy due to the position. For example, an object on the top of a mountain, has the possibility to perform work if it falls.
Electromagnetic energy. is propagated by waves: radio waves, infrared radiation, microwaves, etc.
This is a compound, i remember it because it looks like 3 balls being pushed together.
<u>Explanation:</u>
We are given a mixture of hydrochloric acid (HCl) and acetic acid . The given mixture is a mixture of strong acid and a weak acid.
Strong acid is defined as the acid that can be get completely ionized or dissociated in an aqueous solution. Weak acid is defined as the acid which does not dissociate completely in an aqueous solution.
When a mixture of HCl and is titrated against NaOH (strong base), strong acid will get neutralized first because it is completely dissociated in the solution and can be easily neutralized.
The correct option is:
The latent heat of vaporization of water is given by option D. 22,590J
Latent heat of vaporization:
Latent heat of vaporization is energy required to change 1 kg of liquid to gas at atmospheric pressure at its boiling point.
Also, Latent heat is the energy released or absorbed during a phase change.
Energy released during phase change is Exothermic process.
Whereas energy absorbed during phase change is Endothermic process.
Q=mL
Q= Latent heat
m= mass= 10 g
L= Latent heat of vaporization= 2,259 J/g
Putting the values in the above equation:
Q=10*2259
Q=22590 L
