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
. Water is one of our most important resources. Only about 1% of the Earth's water is for human needs. Name four ways you can help conserve water. This is for science btw...
Answer:please see explanation for answers
Explanation:
Water conservation is an approach geared towards controlling how water is used. Because of the ever growing population, which weighs so much on water available to mankind,Over negligence and abuse of our water resources have been a great point of concern, that is why the need for the knowledge of water conservation is preached.
Now, some of the ways we can conserve water include
1. Putting off taps while lathering the hands with soap
2.use of irrigation system to water crops and plants
3.. while brushing, make sure to turn off the tap or faucet
4. use a shower rather than a bath

Why do you think certain countries favored military solutions to the great depression while other contries did not
Answer:
The answer is below
Explanation:
Certain countries like Germany under Adolf Hitler favored military solutions to the great depression because the government felt that having a mass production of military weapons and recruitment of unemployed people or citizens into the army would change the dire situation.
On the other hand, countries like the United States did not favor the military solutions but instead choose the NEW DEAL under Franklin D Roosevelt; the reason could be linked to their democratic culture, the isolation belief tendency.
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 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
