In Thomson's experiment, he showed that an electrical current can be made to flow from a positive site to a negative site.
The variable is what changes during an experiment. Hopefully this helped! :)
Answer:
B) 0.230 M
Explanation:
The first step is to <u>balance the reaction</u> between the Ferrous ion and the permanganate ion:

Then we have to <u>calculate the moles</u> of
:



Then using the <u>molar ratio</u> we can find the moles of
:

Finally we can calculate the molarity:

The density of CO gas if 0.196g occupies a volume of 100mL is0.00196g<span>mL or 0.00196 grams per milliliter</span>
