well yah .... homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions.
while on the other hand ...A heterogeneous mixture consists of visibly different substances or phases. The three phases or states of matter are gas, liquid, and solid.
there are many differences between these two .... but fr a basic info .... i guess what i said would help .....
Varuable, In algebra, a symbol (usually a letter) standing in for an unknown numerical value in an equation :)
Answer:
P₂ = 0.87 atm
Explanation:
Given data:
Initial pressure = 1.10 atm
Initial volume = 19.2 L
Final volume = 24.3 L
Final pressure = ?
Solution:
The given problem will be solved through the Boyle's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
1.10 atm × 19.2 L = P₂ × 24.3 L
P₂ = 21.12 atm. L/ 24.3 L
P₂ = 0.87 atm

Hydrogen Gas is the free element
