Which of the following would double the pressure on a contained gas at constant temperature?
1 answer:
Answer: C. doubling the number of particles in the container
Explanation: According to the ideal gas equation:'
P= Pressure of the gas
V= Volume of the gas
n= number of moles
T= Temperature of the gas
R = gas constant
As the gas is contained in a container with fixed volume and temperature is also constant.
Therefore, the pressure will double when number of moles or number of particles double.

Answer: The four hybridized orbitals on Sb makes up the sigma bonds between Sb and F in antimony(iii) fluoride ,
Explanation:
According to VESPR theory:
Number of electrons around the central atom :
V = number of valence electrons
N = number of neighboring atoms
C = charge on cation
A = charge on an anion
In antimony(III) fluoride ,
Antimony being central atom: V= 5,N =3,C=0,A=0
Number of electrons :
Number of electrons around the central atom are 4 which means that molecule has four
hybridized orbitals.
