Answer:
purified is as close to pure at you can get

Explanation:
Some aphid species inject a toxin into plants, which causes leaves to curl and further distorts growth. A few species cause gall formations. Aphids may transmit viruses from plant to plant on certain vegetable and ornamental plants. ... The viruses mottle, yellow, or curl leaves and stunt plant growth.
Answer:
The new volume of the balloon is 539 L
Explanation:
As the volume increases, the gas particles (atoms or molecules) take longer to reach the walls of the container and therefore collide less times per unit time against them. This means that the pressure will be less because it represents the frequency of gas strikes against the walls. In this way, pressure and volume are related, determining Boyle's law that says:
"The volume occupied by a given gas mass at constant temperature is inversely proportional to the pressure"
Boyle's law is expressed mathematically as:
Pressure * Volume = constant
o P * V = k
Having an initial state 1 and an final state 2 will be fulfilled:
P1 * V1 = P2 * V2
So, in this case, you know:
- P1= 760 mmHg
- V1= 200 L
- P2= 282 mmHg
- V2= ?
Replacing:
760 mmHg*200 L= 282 mmHg*V2
Solving:
V2=539 L
<u><em>The new volume of the balloon is 539 L</em></u>
