Answer: P=1.63atm
Explanation:
Stp means standard temperature and pressure
Standard temperature =273k
Standard pressure =1atm
Using the formula
P1V1/T1=P2V2/T2
P1= 1atm
V1=5.23L
T1=273k
P2=?
V2=3.45L
T2=293k
Substitute the values
1×5.23/273=p2×3.45/293
Cross multiply
293×1×5.23=p2×3.45×273
1532.39=941.85p2
P2=1532.39/941.85
P2=1.627
P2=1.63atm
Answer:
Noble gases cannot form compunds as they have completely filled orbitals and have stable noble gas configuration
Answer:
As solute concentration increases, vapor pressure decreases.
Step-by-step explanation:
As solute concentration increases, the number of solute particles at the surface of the solution increases, so the number of <em>solvent </em>particles at the surface <em>decreases</em>.
Since there are fewer solvent particles available to evaporate from the surface, the vapour pressure decreases.
C. and D. are <em>wrong</em>. The vapour pressure depends <em>only</em> on the number of particles. It does not depend on the nature of the particles.
