Answer: The thermocline begins at 100 meters of depth.
Step-to-step explanation:-
Thermocline is a transition oceanic water layer between deep and surface water in which water temperature decreases rapidly with increasing depth.
From the given graph it cam be seen that at 100 meters the thermoline begins such that the temperature drops from to .
Hence, the thermocline begins at 100 meters of depth.
Answer:
D. 150 m
Explanation:
Ans: Volume of stock H2SO4 required = 6.94 ml
Given:
Concentration of stock H2SO4 solution M1 = 18.0 M
Concentration of the final H2SO4 solution needed M2 = 2.50 M
Final volume of H2SO4 needed, V2 = 50.0 ml
To determine:
Volume of stock needed, V1
Explanation:
Use the dilution relation:
Hello!
In a school’s laboratory, students require 50.0 mL of 2.50 M H2SO4 for an experiment, but the only available stock solution of the acid has a concentration of 18.0 M. What volume of the stock solution would they use to make the required solution?
We have the following data:
M1 (initial molarity) = 2.50 M (or mol/L)
V1 (initial volume) = 50.0 mL → 0.05 L
M2 (final molarity) = 18.0 M (or mol/L)
V2 (final volume) = ? (in mL)
Let's use the formula of dilution and molarity, so we have:
Answer:
The volume is approximately 6.94 mL
