Which of the following represents the smallest mass? I.) 23 cg II.) 2.3 x 10-3 μg III.) 0.23 mg IV.) 0.23 g V.) 2.3 x 10-2 kg

jenyasd209 [6]

The smallest mass among the choices is Choice (ii):2.3 x 10-3 μg

This is so because, the prefix μ signifies a factor of 10^-6.

For choice I:

23 cg means 23 centigrams

In essence = 0.23grams

For choice II:

2.3 × 10-3 μg means 2.3 × 10-9 grams

For choice III:

0.23 mg means 0.23 × 10-3 grams

For choice IV:

0.23 grams simply means 0.23grams

For choice V:

2.3 × 10-2 kg means 23 grams

Ultimately, Choice II represents the smallest mass.

Answer:

The correct option is: bent 109°

Explanation:

Covalent molecules are the molecules in which the atoms are linked by covalent bonds. The electrons involved in the formation of a covalent bond are known as shared pair or bond pair of electrons.

The three-dimensional arrangement of the atoms of a molecule in space is known its molecular structure or geometry.

Given molecule: XY₂, having two lone pairs around the central atom X.

Since the molecule XY₂ has two lone pairs and two bond pairs of electrons. Therefore according to the VSEPR theory, the given molecule has a bent molecular geometry with 109° bond angle.
