Answer:
P₂ = 2.88 atm
Explanation:
Given data:
Initial volume of gas = 1.8 L
Final volume = 750 mL
Initial pressure = 17.5 Psi
Final pressure = ?
Solution:
We will convert the units first:
Initial pressure = 17.5 /14.696 = 1.2 atm
Final volume = 750 mL ×1L/1000L = 0.75 L
The given problem will be solved through the Boly'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
1.2 atm × 1.8 L = P₂ ×0.75 L
P₂ = 2.16 atm. L/ 0.75 L
P₂ = 2.88 atm
Answer:
Increases
Explanation:
Increasing the temperature increases reaction rates because of the disproportionately large increase in the number of high energy collisions.
Answer:
O atom requires 2 electrons to achieve octet structure and in this structure, it is only bonded to one H atom hence only obtaining an additional valence electron. Without a octet structure, the molecule is unstable hence this structure is incorrect. The correct structure should be H-O-H.
Explanation:
Answer:
16.25 x 10^-20g
Explanation:
molar mass of PCl3
31(1)+3(35.5) = 137.5
n= mass/molar mass
7.14 x 10² = mass / 137.5
mass = 7.14 x 10² x 137.5
mass = 98175g
