Answer:Cs2O + H2O —> 2CsOH [2Cs+ + 2OH-]
Explanation: Cs is the most electropositive element, with electron structure [Xe] 6s1.
Answer:
A
Explanation:
Neutralization reaction is
base + acid ---> salt + water.
It's very simple.......
Velocity= speed + direction
Velocity is the speed in which you know the direction of speed !!!
fluorine is an element on it's own so no
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
