Answer:
V CH3OH = 262.5 mL
Explanation:
- %v/v = (v compound / v sln)×100
∴ %v/v = 21.0 %
∴ v sln = 1.25 L
⇒ v compound = ?
⇒ 21.0 % = ( v compound / 1.25)×100
⇒ 0.21 = v compound / 1.25 L
⇒ (0.21)*(1.25 L) = v compound
⇒ v compound = 0.2625 L = 262.5 mL
Answer: Chemicals become positively charged by loosing electrons.
Explanation: There are three types of compounds:
1) Neutral compounds: These are the compounds where equal number of protons and electrons are present.
2) Positive compounds: These are the compounds where number of protons are more than the electrons. These are considered as cations.
3) Negative compounds: These are the compounds where number of electrons are more than the protons. These are considered as anions.
So, in order to have a positive charge on a compound, that compound has to loose electrons, so that the number of protons gets higher than the number of electrons.
