Covalent bonds keep the hydrogen and oxygen atoms together
The new concentration of the solution is 0.016 M
<h3>Dilution</h3>
From the question, we are to determine the concentration of the new solution prepared from question 4.
NOTE: Question is provided below
From question 4, the concentration of the sodium chloride solution is 0.200M
Now, to determine the new concentration,
Using the dilution law
C₁V₁ = C₂V₂
Where
C₁ is the initial concentration
V₁ is the initial volume
C₂ if the final concentration
and V₂ is the final volume
Then,
C₁ = 0.200 M
V₁ = 10.00 mL
C₂ = ?
V₂ = 125.00 mL
Then,
0.200 × 10.00 = C₂ × 125.00

C₂ = 0.016 M
Hence, the new concentration of the solution is 0.016 M
Question 4:
Calculate the amount of solid sodium chloride needed to make 200.00 mL of a 0.200 M solution

Answer:
D. all of these
Explanation:
In the classification of organisms, they are placed into groups which they appropriately fit into.
All the choices given correctly shows the process of classifying organisms. This aspect of biology is described as taxonomy.
- Based on characteristics of organisms, they are put into the same groups
- Also, we can identify the related family and genus in which a discovered organism can be put into.
- They phylogenetic relationship between organisms are important for classification.
