Answer:
B.
Explanation:
I believe it is B, it could be C too.
Answer:
Cl2(g) (green/yellow mix) + 2KBr(s) (white) ---> 2KCl(s) (violet) + Br2(g) (reddish brown)
This chemical reaction is a redox type.
Explanation:
Look at the oxidation state, when the number increase your element gets oxidated, when the number decrease, the elements it's getting reduced.

Answer:
0.2625L
Explanation:
Given parameters":
Volume of solution = 1.25L
Percentage concentration = 21%
Unknown:
Volume of methanol = ?
Solution:
The percentage concentration is one of the different methods for expressing concentration values.
It is given as:
Percentage concentration = ![\frac{Volume of solute}{volume of solution} x 100](https://tex.z-dn.net/?f=%5Cfrac%7BVolume%20of%20solute%7D%7Bvolume%20of%20solution%7D%20%20x%20100)
Now we have to work backwards to derive the percentage concentration;
let the unknown, the volume of methanol which is the solute = P;
21 =
x 100
21 = ![\frac{100p}{1.25}](https://tex.z-dn.net/?f=%5Cfrac%7B100p%7D%7B1.25%7D)
21 = 80p
p = 0.2625L
