Answer: 3.7 x10−6 Mole per dm^3
Explanation:
pH is the negative logarithm of hydrogen ion concentration in a solution.
So, pH = - log(H+)
Since the solution has a pH of 5.43
5.43 = -log(H+)
To get hydrogen ion concentration, find the Antilog of 5.43
(H+) = Antilog (-5.43)
(H+) = 0.000003715
Then, 0.000003715 in standard form becomes 3.7 x10−6 M
Thus, the concentration of hydrogen ion in the solution is 3.7 x10−6 Mole per dm^3
To me it looks like gas.
Gas- CORRECT!
Solid- incorrect because if this were a depiction of a solid then the particles would be much much closer together.
Liquid - incorrect because the particles would be a little more crowded together.
Plasma- I do not think that this answer is correct because, even though the spacing of particles is similar to the spacing of particles in plasma, the particles in plasma are charged particles(nuclei (+) and electrons(-)). Therefore, because the diagram doesn't have the particles labeled with charges, I believe that Plasma cannot be the correct answer.
Any questions?
Answer:-
Phosphorus
Explanation:-
In the third period among the elements given, phosphorus is at the most right side among them in the periodic table.
We know that as we go from left to right in the periodic table, the atomic size decreases due to the increase in nuclear charge.
Hence phosphorus is the smallest among them
The mass number is the total of protons and neutrons. The atomic number of sulfur<span> is 16 so it has 16 protons.
so its sulfur</span>
Answer:
The pH would go up
Explanation:
This is because sea water has a pH of around 8.1, and washing powder is a basic substance, with most detergent products having a pH of 10. The combination of both these substances would result in a alkaline solution with a higher pH than before
