Answer:
Two non bonded electron pairs and four bonded electron pairs
Explanation:
An image of the compound as obtained from chemlibretext is attached to this answer.
The ion ICl4- ion, is an AX4E2 ion. This implies that there are four bond pairs and two lone pairs of electrons. As expected, the shape of the ion is square planar since the lone pairs are found above and below the plane of the square. This is clear from the image attached.
Answer:
Explanation:
Oxygen has eight eletrons and six valence electrons, giving it the electron configuration of .
Answer:
The weight-average molar mass of polystyrene is 134,160 g/mol.
Explanation:
Molar mass of the monomer styrene , , M=104 g/mol
Given , number average molar mass of the polymer , M'= 89,440 g/mol
Degree of polymerization = n
The weight-average molar mass =
Molar mass dispersity is ratio of weight-average molar mass to the number average molar mass of the polymer.
The weight-average molar mass of polystyrene is 134,160 g/mol.
