Answer:
3.4moles
Explanation:
Given parameters:
Number of molecules = 2.04 x 10²⁴
Unknown: Number of moles
Solution
We use the concept of mole to solve this kind of problem.
A mole is the amount of substance that contains Avogadro's number of particle i.e 6.02 x 10²³ molecules
Solving
For elementary particles:
Number of moles = 
¹ molecules
Number of moles = 
Number of moles of H₂O = 0.34 x 10¹ = 3.4moles

Explanation:
oxidation of Nitrogen in NO2 is +4
To balance a chemical reaction, we need to remember that the number of each atom in the reactant and the product side of the equation should be equal. So, from the reaction <span>P4(s) + Cl2(g) = PCl3(l), there are 4 P atoms in the reactant, the P atoms in the prodcut side should be 4 as well. We balance as follows:
</span> P4(s) + 6Cl2(g) = 4PCl3(l)
<span>
Therefore, the coefficient of the PCl3 should be 4.

Answer:
The answer to your question is Sediment C
Explanation:
Permeability is the property of passing through a material without physically or chemically affecting it.
If a substance is very permeable, it will pass through a material rapidly others substances can be permeable but can not pass through the material quickly.
In the data given, we can conclude that the third substance is the least permeable because less quantity of water has passed through it.
