Answer:

a). Nepthalene is a D2h molecule because it has 3 C2 axes which are perpendicular and it has a mirror plane which is horizontal. Moreover C2 is taken as principal axis.

b). 1,8-dichloronaphthalene is a C2v molecule beccause it has 1 C2 axis, two rings are joined by the C-C bond and it also has two mirro planes.

c). 1,5-dichloronaphthalene is a C2h molecule because it has only 1 C2 axis which is pependicular to the plane, it has an inversion center and also a mirror plane which is horizontal in position.

d). 1,2-dichloronaphthalene is a Cs molecule because it has only a mirror plane.

What type of bond is Na3PO4?; Is Na3PO4 ionic or molecular?; Does Na3PO4 have ionic and covalent bonds?; Is Na3PO4 a polyatomic

Leni [432]

The type of the bond is present Na₃PO₄ is the ionic bond. the Na₃PO₄ is the ionic compound. yes the Na₃PO₄ is the polyatomic ion.

The Na₃PO₄ is Na⁺ and PO₄³⁻. the phosphorus is the non metal and the oxygen atom is the non metal. the non meta and non meta form the covalent or molecular bond. the bond between the PO₄³⁻ bond is the covalent bond but the overall present in the Na₃PO₄ is the ionic bond . the bons in between the Na⁺ and PO₄³⁻ is the the ionic bond. the PO₄³⁻ id the polyatomic ion .

The bond between the positively charged ion and the negatively charged ion are called as the ionic bond and the compound form is the ionic compound.

Answer:

12.084 lb

Explanation:

1 gram = 0.00220462 lb

multiply number of grams by 0.00220462

Ex. 2000 g x 0.00220462 = 4.409 pounds

A uranium atom is 238 times as massive as a hydrogen atom. The diameter of a uranium atom is the diameter of a hydrogen atom tim

ser-zykov [4K]

Answer:

A. 3

Explanation:

Given

The atomic radius of Hydrogen rH = 53 pm

The atomic radius of Uranium rU = 156 pm

we apply

rU / rH = 156 pm / 53 pm

⇒ rU / rH = 2.943 ≈ 3

then

rU = 3*rH
