Answer:

Seismic waves

Explanation:

The seismic P and S waves are two waves that releases energy during propagation, resulting in the sudden shaking of the earth, which is commonly known as the earthquake.

The point from which the earthquake originates, is known as the focus and the location that is directly above the focus, on the ground surface is known as the epicenter.

The P waves and S waves are primary and secondary waves respectively. The P waves are characterized by the contraction and expansion in its direction of propagation. Whereas the S waves are shear waves.

First, let's start off by finding the mass of this whole hydrate.
(Note: the unit of measurement for mass will be amu)

Let's find the molecular mass of each element.
Co=58.933
Cl=35.45
H=1.008
O=15.999

Now, let's find the mass of each compound.

CoCl_2=58.933+2(35.45)=129.833
H_2O=2(1.008)+15.999=18.015

We have 6 molecules of H2O, so multiply 18.015 by 6 then add that with the weight of CoCl2.

6(18.015)=108.09
129.833+108.09=237.923

Now divide 108.09 (mass of all the H2O in the hydrate) by 237.923 (total mass of hydrate).

\dfrac{108.09}{237.923}

\approx0.45431

Turn that into a percentage and you get 45.431%.
Hope this helps! :)

Which of an atom's electrons are inrolved in chemical reactions?
Scrat [10]

Answer:

Electrons at the outermost energy level of an atom are called valence electrons. They determine many of the properties of an element. That's because these electrons are involved in chemical reactions with other atoms. Shared electrons bind atoms together to form chemical compounds.
