Answer:
The partial pressure of argon in the flask = 71.326 K pa
Explanation:
Volume off the flask = 0.001 
Mass of the gas = 1.15 gm = 0.00115 kg
Temperature = 25 ° c = 298 K
Gas constant for Argon R = 208.13 
From ideal gas equation P V = m RT
⇒ P = 
Put all the values in above formula we get
⇒ P = 
× 208.13 × 298
⇒ P = 71.326 K pa
Therefore, the partial pressure of argon in the flask = 71.326 K pa

Answer:
The number of atoms of aluminum contained in one square inch of the foil=6
Explanation:
Interpretation:
The number of atoms of aluminum contained in one square inch of the foil is to be calculated.
Concept introduction: relation to calculate a number of atoms contained in one square inch of the foil is given by:
NA/c=mNA/AA1
Where,
M=mass of aluminum
NA= Avogadro's number
AA= Atomic mass of aluminum
Given :
Mass of aluminum foil=0.3 g
M= 0.39g
Relation to calculate a mass of atoms contained in one square inch of the foil is given by:
NA/c= mNA/AA1
M= Mass of aluminum
NA= Avogadro's number
AA= Atomic mass of aluminum
Since,
Avogadro's number
=6
The molecular geometry of a molecule with a core atom that has five areas of electron density and precisely one lone pair of electrons is called a disphenoidal or seesaw molecular geometry.
What is meant by disphenoidal or seesaw molecular geometry?
- Four bonds are made to an atom in the center of a disphenoidal or seesaw-shaped molecular structure, which has overall C2v structural symmetry. The fact that it resembles a playground seesaw is how it got the moniker "seesaw." Tetrahedral or, less frequently, square planar geometry is produced when four bonds to a center atom are present.
- The core atom of a molecule with a steric number of 5 and bonds to 4 additional elements and 1 lone pair is said to be in the seesaw geometry.

The answer is B) Accurate. Authentic in this case basically means Accurate. They try to create accurate models. Plus, it is the only one that really actually makes sense.
