So that it follows the law of conservation of mass
A horizontal exempted is a bit tight but I think it’s a good idea
I think c cause if he is in a relationship that’s abusive he needs to speak up before it goes way worst.
The 0.25 volume in liters of 1.0 M
solution is required to provide 0.5 moles of
(aq).
Calculation,
The Potassium carbonate dissolves as follows:
→ 

The mole ratio is 1: 2
It means, the 1 mole
required to form 2 mole of
(aq).
To provide 0.5 mole of
(aq) = 1 mole ×0.5 mole /2 mole required by
.
To provide 0.5 mole of
(aq) ,0.25 mole required by
.
The morality of
= 1 M = number of moles / volume in lit
The morality of
= 1 M = 0.25 mole/ volume in lit
Volume in lit = 0.25 mole / 1 M = 0.25 mole/mole/lit = 0.25 lit

Hexane and 2-methylpentane. If you draw the structures out, you can see that both isomers have 6 carbon atoms and 14 hydrogen atoms. Hence they have the same molecular formula but a different structural formula. I suggest drawing the compounds out for these types of questions to visualise it.
