Since there is no "new" chemicals made during this process, it is considered a physical change. Distillation is a process of separating dissolved solids or liquids with different boiling points without chemically changing anything.
Color change, formation if a new substance or altering molecular structure are all general signs of chemical change.
Therefore, the last answer choice looks like the best answer.
Hope that helps!
Answer is either B or all of the above. “G” is not an element on the periodic table. If it’s not a typo, then the answer is B.
Answer:
3.5 atm
Explanation:
Given data
- Initial pressure (P₁): 47.9 atm
- Initial volume (V₁): 21 L
We can find the maximum pressure that the gas can exert (final pressure) using Boyle´s law.
P₁ × V₁ = P₂ × V₂
P₂ = P₁ × V₁ / V₂
P₂ = 47.9 atm × 21 L / 290 L
P₂ = 3.5 atm
