Answer: 41 atmosphere
Explanation:
Given that:
Volume of water V = 0.5 L
(since 1 liter = 1dm3
0.5L = 0.5dm3)
Temperature T = 500K
Pressure P = ?
Number of moles of gas = 5 moles
Note that Molar gas constant R is a constant with a value of 0.0082 ATM dm3 K-1 mol-1
Then, apply ideal gas equation
pV = nRT
p x 0.5dm3 = 5 moles x (0.0082 atm dm3 K-1 mol-1 x 500K)
p x 0.5dm3 = 20.5 atm dm3
p = (20.5 atm dm3 / 0.5dm3)
p = 41 atm
Thus, the gas is under a pressure of 41 atmosphere
The basic unit of mass in the metric system is grams
Hey there!
No of hybrid orbitals , H = ( V +S - C + A ) / 2
Where H = no . of hybrid orbitals
V = Valence of the central atom = 5
S = No . of single valency atoms = 4
C = No . of cations = 1
A = No . of anions = 0
For PCl4 +
Plug the values we get H = ( 5+4-1+0) / 2
H = 4 ---> sp3 hybridization
sp3 hybrid orbitals are used by phosphorous in the PCl4+ cations
Answer C
Hope that helps!
