Explanation:
Hello!
In this case, since we are given the formula units (molecules) of copper sulfate, it is possible to compute the moles of this compound via the Avogadro's number:
Now, given the molar mass of copper sulfate which is 159.60 g/mol, the required mass in grams turns out:
Best regards!
Answer:
0
Explanation:
Since HI is a strong acid, the amoung of Hydrogen ions produced by it will be the same molar as the reactant. The negative log of the concentration will reveal that the pH is 0.

Hey there!
Here is your answer:
<u><em>The proper answer to this question is "pressure, deposition, and compaction".</em></u>
Reason:
<u><em>Sedimentary are formed by pressure, deposition, compaction. Which should be in one of your answer choices.</em></u>
Also....
<u><em>This would help you strike out options you don't need, igneous rocks are formed by cooling of magma or lava, and metamorphic rocks are formed by heat and pressure under the Earths surface.</em></u>
If you need anymore help feel free to ask me!
Hope this helps!

Answer:
C. Na⁺ is entering the cell.
Explanation:
In the depolarization phase, the permeability of sodium ions (Na⁺) increases, allowing a large flow of sodium ions to enter the cell through the membrane by simple diffusion.
This process causes intracellular liquids to be <u>positively</u> charged due to the large amount of cations.
