Answer: stress caused by plate movement
Explanation:
Earthquakes are caused by the movement of tectonic plates, the different types of movements being divergent, convergent and transform.
Divergent boundaries: where new crust is generated as the plates pull away from each other.
Convergent boundaries: where crust is destroyed as one plate dives under another.
Transform boundaries: where crust is neither produced nor destroyed as the plates slide horizontally past each other.

Answer:
0.544 M
Explanation:
First find the moles in the final solution
0.8 mols/L *1.7L
1.36 mols
so there is 1.36 mols in 2.5L
concentration will be 1.36/2.5
0.544 M
16(2)/74.1=.431
.431x100= 43.1%
