Explanation:
A is one because a seismograph measures seismic waves to gauge the intensity of an earthquake, such as B, P Waves, which are the earliest waves, the ones that tell you an earthquake is coming.

When Δ H > 0 that means this is an endothermic reaction, and we can assume heat as one of the reactants. SO when the temperature increases so the reaction will move rightward to decrease the reactants and increase the products and as the products increase it will make the Kw increase also as
Kw = [Products] /[reactants].
So our answer will be: the value of Kw will increase.
Atomic mass = 39
number of neutrons = 20
Number of protons= 19
Electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1
The number of electron in first shell = 2
number of electrons in n=3 shell = 8
