What type of wave can actually reach Earth's inner core
kenny6666 [7]
I believe body waves can actually reach the core as they follow raypaths refracted by the varying density and modulus of Earths interior.

Hope this helps!

Determine the number of moles of aluminum in 2.154 x 10-1 kg of Al. Group of answer choices 5816 mol 7.984 mol 6.02 X 1023 mol 4
Jlenok [28]

Answer:

Avogadro's number is 1 mol  = 6.02 * 10^23 elements

It means that 1 mol of atoms is 6.02 * 10^23 atoms

1 mol of atoms = 6.02 * 10^23 atoms

From there, if you divide both sides by 1 mol of atoms, you get

1 = 6.02 * 10^23 atoms / 1 mol of atoms.

That means, that to pass from a number of moles of atoms to number of atoms you have to multipby by the conversion factor

         6.02*10^23  atoms Al/ 1 mol Al

That is the second option of the list.

When cobalt chloride is added to pure water, the co2 ions hydrate?
mrs_skeptik [129]
Answer : The question is incomplete and the complete question is attached in the answer;

Answer 1) When HCl was added to the system of cobalt chloride it will eventually produce more Cl ions in the solutions which will shift the equilibrium to the right and make the solution look more blue than before. To accommodate extra Cl ions in the system the equilibrium gets shifted. 

Answer 2) When in the reaction system water is added the Cobalt chloride compound forms a hydrated mixture; this means the equilibrium reaction shifts to the left and produces more hydrated ions along with more chlorine ions in the solution.

Which then turns the resultant solution tinto pink in colour.
