Volume of 100 drops: 0.43 dL
Explanation:
We can solve this question by applying the rule of three.
In fact, we know that:
- The volume of 1 drop of medicine is 0.43 mL, so the ratio between number of drops and volume (in mL) is 1 : 0.43
- Then we want to find the volume of 100 drops
So we can write the following equation:
where V is the volume of 100 drops.
Solving for V,
And keeping in mind that
1 dL = 100 mL
We can convert into deciliters:

<u>Answer:</u>
a. Oxidising agent: Cl₂
b. Reducing agent: NaBr
c. Oxidised: NaBr
d. Reduced: Cl₂
e. Oxidation numbers before reaction: Cl= 0, Na= +1, Br= -1
f. Oxidation numbers after reaction: Cl= -1, Na= +1, Br= 0
<u>Explanation:</u>
Oxidising agents reduces themselves, oxidising other elements/compounds.
Reducing agents oxidise themselves, reducing other elements/compounds.
Oxidation is the <u>loss</u> of electrons or an <u>increase</u> in oxidation number.
Reduction is the <u>gain</u> of electrons or <u>decrease</u> in oxidation number.
The answer is E and F.
