Answer and Explanation:
<u>D) 7 is the answer</u>
Together, the crust and the upper part of the mantle form the lithosphere, Earth's solid outer shell. This rocky, brittle layer is broken up into seven major and several minor tectonic plates (also known as lithospheric plates) that fit together like puzzle pieces.

When Na2S2O3 dissolves in water, it dissociates into Na+ and S2O32- ions:
Na2S2O3 ⇒2Na+ + S2O32-
So 1 mole of Na2S2O3 generates 2 Na+s.
The moles of Na2S2O3 = volume of Na2S2O3 * molarity of Na2SO3 = 0.01L * 0.15mol/L = 0.0015 mol.
Therefore, the moles of Na+ in the solution = 0.0015mol * 2 = 0.003 mole.
Answer:
1.59 atm
Explanation:
The reaction is:
The dalton's law tell us that the total pressure of a mixture of gases is the sum of the partial pressure of every gas.
So after the reaction the total pressure is:
we don't include because it decomposed completely.
Assuming ideal gases
PV=nRT
P= pressure, V= volume of the container, n= mol of gas, R=constant of gases and T=temperature.
so moles of is:
from the reaction stoichiometry (1:1) we have that after the reaction the number of moles of each product is the same number of moles of .
The partial pressure of each gas is:
so total pressure is:
replacing the moles we get:
We know that T2=3*T1
replacing this value in the equation we get:
