If I am not mistaken, Seismic waves can penetrate the outer and inner core but can't travel through water very well.
Hope this answer helps! feel free to ask any additional questions :)
Cones are sensitive to color
A collision hypothesis that claims a chemical reaction can only happen when reactants collide at the right angle and with enough kinetic energy.
<h3>What in chemistry is a reactant?</h3>
A material that's also present at the outset of such a chemical reaction is known as a reactant. Products are the substrate(s) to the side of the arrow. A component that remains after a chemical reaction is finished is known as a product.
<h3>Which side are the products and reactants?</h3>
The chemicals (what you started with) be transformed into byproducts in a chemical process (what you end with). An arrow separates the reaction mixture, which are indicated on the left side of a solution, from the products, who are depicted on the right.

<h3>Answer</h3>
Heat : 12 kJ, to maintain hydrogen bonds
<h3>Further explanation</h3>
Given
A 2.00mole sample ⇒ n = 2 mol
H₂O(s) at 0°C melted, producing H₂O(l) at 0°C
Required
the amount of heat required
the changes that took place
Analysis
Conversion of mol to mass
Use formula of Heat :
Q = mLf (melting/freezing)
Lf=latent heat of fusion (for water=334 J/g)
Solution
mass H₂O(MW=18 g/mol) :
Heat required :
The absorbed heat is used to maintain hydrogen bonds in water molecules (there are two hydrogen bonds per molecule)
Paraphrase
The amount of heat required : 12 kJ, and to maintain hydrogen bonds
The main formula is
% = molar mass of elements / total molecular molar mass) x100
<span>M (Ca(C2H3O2)2) = 2*(12*2 +3*1+16*2) + 40=158
so
</span>%Ca= 40/158<span>x 100=0.25</span><span>x 100= 25%
</span>
%C= 12/158 x 100= 0.07x 100=7%
%H= 1/158x 100=0.006x 100=0.6%
%O=16/158x 100= 0.101x 100= 10.12%
