1. during an oceanic plate convergence, the plate will sink
2. the west coast of the united state has features formed by
3. during the of two tectonic plates, magma wills the space between two tectonic plates.
4. the only volcanic activity that is not formed at tectonic plate boundaries is
and volcanoes are linked severe weather events.
respond to the following based on your reading.
6. why does underwater hot-spot volcanism tend to form chains of islands? for that matter, why
doesn't it form one huge, single island?

1. denser

2. subduction

3. divergence

4. hot spots

5. earthquakes

6. An underwater hot-spot volcano occasionally erupts, and the lava solidifies into an island. However, the plate that lies above the hot spot continues to move due to slab pull and ridge push, so the stationary volcano will be in a different location when it erupts again. This forms a new island, and the process may continue.

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
