Answer: Because fresh water is constantly be evaporated from the ocean and then replaced by rivers, the salinity of the oceans remains balanced.
Explanation:
When evaporation takes place in sea water then of course there will occur an increase in salinity.
But as this evaporated water is replaced by water coming from rivers. As a result, the raising salinity is counter balanced by the water coming from rivers.
Hence, salinity remains balanced in sea water.
Thus, we can conclude that because fresh water is constantly be evaporated from the ocean and then replaced by rivers, the salinity of the oceans remains balanced.

What effect does the Earth's surface have on solar radiation?
Answer:
Thus, the proportion of Earth's surface that is covered by ice and snow affects how much of the Sun's solar radiation is absorbed, warming the planet, or reflected. Therefore, snow and ice which are covered in soot from pollution no longer reflect sunlight, but absorb it and so melting increases.
Answer:
Half of the solar radiation is absorbed and converted to infrared (heat).
Explanation:
How much 0.05 M HCl solution can be made by diluting 2L of 10 M HCl?
Answer:
400 L
Explanation:
As this problem deals with a dilution process, we can use the following formula:
C₁V₁=C₂V₂Where subscript 1 stands for the concentrated concentration and volume, while 2 stands for the diluted values. Meaning that in this case:
C₁ = 10 MV₁ = 2 LC₂ = 0.05 MV₂ = ?We input the data:
10 M * 2 L = 0.05 M * V₂And solve for V₂:
V₂ = 400 LIf you diluted 120 mL of 1,049 M NaCl to 1,920 mL, what would
be the new concentration of NaCl? Don't put units into your
answer.
Answer:
65.56 M
Explanation:
Using the formula as follows:
C1V1 = C2V2
Where;
C1 = initial concentration (M)
C2 = final concentration (M)
V1 = initial volume (L)
V2 = final volume (L)
According to the information in this question,
C1 = 1,049 M
C2 = ?
V1 = 120 mL
V2 = 1,920 mL
Using C1V1 = C2V2
1049 × 120 = C2 × 1920
125880 = 1920C2
C2 = 125880 ÷ 1920
C2 = 65.56 M
How many atoms are in 1.204x10^22 moles of arsenic?
Answer:
0.02 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
We have
[tex]n = \frac{1.204 \times {10}^{22} }{6.02 \times {10}^{23} } \\ = 0.02[/tex]
We have the final answer as
0.02 molesHope this helps you
