Answer:
Becquerel was studying the properties of X-Rays when he discovered radioactivity. His original theory was that X- Rays arose from uranium absorbing...
Explanation:
<u>Answer:</u>
<em>That oxidation number of chlorine is -1 while that of oxygen is -2</em>
<u>Explanation:</u>
When it comes to manganese chloride to stabilize the chlorine Ion. Two manganese ions shall be required. Hence the formula for the compound becomes
while the formula for manganese (iv) chloride will be
similarly.
When oxygen and magnesium oxide is considered the Two ions of Manganese will satisfy to ions of oxygen. Which cancels and becomes
while for manganese (iv) oxide the formula becomes
.
Answer:
To prepare vegetables for finishing by grilling, sautéing, pan frying, deep frying, or stewing, you should parboil them to cook them to partial doneness.
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!
