Answer:
V2 = 9.58 Litres.
Explanation:
Given the following data;
Initial volume = 25 L
Initial pressure = 115 kPa
Final pressure = 300 kPa
To find the new volume V2, we would use Boyles' law.
Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.
Mathematically, Boyles law is given by;
Substituting into the equation, we have;
V2 = 9.58 L
Therefore, the new volume is 9.58 litres.
Answer:
Explanation:
In a single-displacement reaction, one element exchanges partners with another element in a compound.
This is a single-displacement reaction, because the element Fe exchanges partners with H in HCl.
This is not a single-displacement reaction, because it is a reaction between two compounds.
This is a double displacement reaction in which the K⁺ and H⁺ cations change partners with the anions.
This is not a single-displacement reaction. It is another double displacement reaction, in which the Na⁺ and H⁺ cations change partners with the anions.
This is a single-displacement reaction, because the element Ca exchanges partners with H in H₂O.
are not single-displacement reactions.
