Final answer:
The electron pair geometry of a phosphine, PH3, molecule is tetrahedral, though the molecule itself takes on a trigonal pyramidal shape due to the presence of a lone pair of electrons on the phosphorus atom.
Explanation:
The electron pair geometry for a phosphine molecule, PH3, is tetrahedral. In PH3, the phosphorus atom is the central atom surrounded by three hydrogen atoms. However, it is important to note that the phosphorus atom also has a lone pair of electrons. The lone pair occupies more space than bonding pairs, causing the molecule to take on a trigonal pyramidal molecular geometry. Despite the molecular geometry, the electron pair geometry is considered tetrahedral because it accounts for all regions of electron density, including lone pairs.

Final answer:
The electron pair geometry for a phosphine molecule (PH3) is tetrahedral. This refers to the spatial arrangement of regions of electron density around the central atom, phosphorus, which is bonded to three hydrogen atoms and has one lone pair of electrons.
Explanation:
The electron pair geometry for a phosphine molecule, PH3, is best described as tetrahedral. Even though the PH3 molecule is not tetrahedral, the electron pair geometry refers to the spatial arrangement of regions of electron density around the central atom, in this case, phosphorus. Phosphorus in the PH3 molecule is bonded to three hydrogen atoms and has one lone pair of electrons. These four regions of electron density adopt a tetrahedral arrangement to minimize electron-electron repulsion. Please note that the molecular structure of PH3 is trigonal pyramidal as lone pairs are not included while determining the molecular geometry.

Answer:
Br - C ≡ N
Explanation:
To draw the Lewis line-bond structure we need to bear in mind the octet rule, which states that in order to gain stability each atom tends to share electrons until it has 8 electrons in its valence shell.
- C has 4 e⁻ in its valence shell so it will form 4 covalent bonds.
- Br has 7 e⁻ in its valence shell so it will form 1 covalent bond.
- N has 5 e⁻ in its valence shell so it will form 3 covalent bonds.
The most stable structure that respects these premises is:
Br - C ≡ N
It does not have any H atom.

Answer:
The ratio of solution 1 to solution 2 is 24.20 to 100.00.
Explanation:
We will mix V₁ (L) of solution 1 with V₂ (L) of solution 2 to get the final solution.
So the mole concentration in the final solution is calculated as below, note that C₁ is the concentration of solution 1, and C₂ is the concentration of solution 2
Then we can calculate for the ratio
