Answer:
2.1 M
Explanation:
The dilution equation is
.
= the molarity of the sock solution
= the volume of the sock solution
= the molarity of the diluted solution
= the volume of the diluted solution
The stock solution would be what is doing the diluting, so "175 mL of a 3.00 M solution". So
= 3.00 M. Then: Converting 175 mL to liters:
(This is
)
And converting 250 mL KCl to liters:
(This will be
)
Then, we plug in our given into the dilution equation, resulting in:
(divide both sides by 0.250 L, in order to get
by itself)


So, the molarity of 250 mL KCl made by diluting 175 mL of a 3.0 M solution would be 2.1 M (mol/L).
Hopefully this helped you understand the topic a little bit better. I just finished molarity and dilutions in Chemistry last week. Good luck!
The answer is: True
I took the quiz and it was correct
It turns into a gas when it evaporates
Answer:
Explanation:
The mechanical properties of a material affect how it behaves as it is loaded. The elastic modulus of the material affects how much it deflects under a load, and the strength of the material determines the stresses that it can withstand before it fails
Answer:
b. Lithium
Explanation:
<u>Lithium-ion batteries (LIB) is a rechargeable battery</u>. It was first proposed by M stanley Whittingham in 1970s. These kind of batteries are commonly used in electrical vehicles and portable electronics. It also have military , naval and aerospace applications.
<u>
In LIB, the lithium ions move from the negatively charged electrode to the positively charged electrode during the discharge process and move in the reverse direction when the during the charging process.</u> The battery uses an intercalated lithium compound is used to form anode and graphite is used to form cathode.
<u>Thus, Lithium is oxidized/reduced in a lithium ion battery.</u>
