Give the following for SO2 and BrF5:
frosja888 [35]

Answer:

The given molecules are SO2 and BrF5.

Explanation:

Consider the molecule SO2:

The central atom is S.

The number of domains on S in this molecule is three.

Domain geometry is trigonal planar.

But there is a lone pair on the central atom.

So, according to VSEPR theory,

the molecular geometry becomes bent or V-shape.

Hybridization on the central atom is

sp^{2}.

Consider the molecule BrF5:

The central atom is Br.

The number of domains on the central atom is six.

Domain geometry is octahedral.

But the central atom has a lone pair of electrons.

So, the molecular geometry becomes square pyramidal.

The hybridization of the central atom is sp^{3} d^{2}.

The shapes of SO2 and BrF5 are shown below:

A cube with sides 3cm.Its mass is 54g. will it sink or float
zloy xaker [14]

Answer:

It will sink.

Explanation:

Density of water=1gm/cc (In CGS)

Volume of cube=l^3 =3^3= 27cc

Mass of cube =54gm

Density of cube=M/V =54/27 =2gm/cc

Here, density of cube is greater than that of water. So, the cube sinks.
