Pretty sure it shows a chemical reaction
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

Answer:
The CO2 Extinguisher Cannisters contain carbon dioxide in liquid form, and when the extinguisher is let off the liquid is released into the air neutralising the oxygen that the fire is feeding on, disabling the fires ability to spread.
Answer:
C. Chemical change
Explanation:
A physical change is where something is changed but it doesnt affect the build up of the chemical. For example, if you broke sticks and threw them on the ground, that would be a physical change because the change is happening to the physical being of the object and not its chemical buildup. However, if you lit those sticks on fire, that would be considered a chemical change because you end up with two substances, ash and the remnants of the stick. A nuclear reaction would result in something blowing up so its not that. And a physical property is like what it looks like or how it smells. Hope I helped you!
450.0 ML because it has more solution and it would be better if the sciences users it
