Answer:
P₂ = 0.8 atm
Explanation:
Given data:
Initial pressure = 1 atm
Initial volume = 7 L
Final volume = 9 L
Final pressure = ?
Solution:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = Initial volume
P₂ = Final pressure
V₂ = Final volume
Now we will put the vales in formula.
P₁V₁ = P₂V₂
P₂ = P₁V₁ /V₂
P₂ = 1 atm × 7 L / 9 L
P₂ = 7 atm. L / 9 L
P₂ = 0.8 atm
Answer:
Its a physical
theres no chemical properties involved.

A. Scientists don't stop with the first step of their experiment because they don't think that just using their observations is a very good place to start to prove their hypothesis.
B. Scientists don't stop with the first step of their experiment because they not only want to observe but they want to test their observations to be sure they are correct.
C. Scientists don't stop with the first step of their experiment because they want other scientists' opinions because they may not trust their own observations.
D. Scientists don't stop with the first step of their experiment because they would rather plan and run experiments than just observe the world around them.
electrolyte
hydration
ionization
Answer : The correct option is, hydration
Explanation :
Hydration : It is a process in which the ion or substance combines with water and kept in the solution. In the hydration process the solvent is water molecule.
For example : When the sodium chloride is dissolved in the water then the positive sodium ion get surrounded by the water molecule through their oxygen ends and the negative chloride ion get surrounded by the water molecule through their hydrogen ends.
Dissociation : It is a process in which the compound splits or dissociates into to two or more smaller ions, atoms or particles.
Electrolyte : it is a process in which the a molecule is completely dissociates into their respective ions in the aqueous solution.
Ionization : It is a process in which a molecule acquire a positive or negative charged by the gaining or losing electrons.
Hence, the correct option is, hydration.
