#SPJ4
Salt at higher concentrated levels causes soil aggregates to break down, collapsing soil pores and reducing movement of air and water, thus causing less water infiltration and increased erosion. All of this creates a surface above the soil and once it dies it creates a crust like blockade, keeping saplings from breaking through. This also basically suffocates the plants already living there. Hope it helped!!
my answer would be
fluorine, chlorine, oxygen
Answer:
8.90 M
Explanation:
Step 1: Given data
-
Initial concentration (C₁): ?
- Initial volume (V₁): 635 mL = 0.635 L
- Final concentration (C₂): 5.00 M
- Final volume (V₂): 1.13 L
Step 2: Calculate the initial concentration
We have a concentrated NaCl solution and we want to prepare a diluted one. We will use the dilution rule.
<em>
C₁ × V₁ = C₂ × V₂
</em>
C₁ = C₂ × V₂ / V₁
C₁ = 5.00 M × 1.13 L / 0.635 L
C₁ = 8.90 M
