Oxygen

Question 1

Elemental form of oxygen

Answer 1

Diatomic

Question 2

State form of O2 in athmospheric conditions

Answer 2

Gas

Question 3

O2 magnetism

Answer 3

Paramagnetic

Question 4

O2 electronegativity

Answer 4

High

Question 5

Bond order of O2

Answer 5

2

Question 6

Molecular geometry of O2

Answer 6

Linear

Question 7

Bond of O2

Answer 7

Double bond with high binding energy, that’s why it’s really stable.

Question 8

Smell and taste of O2

Answer 8

Odorless and tasteless

Question 9

Solubility in water of O2

Answer 9

Low, but really necessary in the sea for the life.

Question 10

Formation of atomic oxygen

Answer 10

Thermal dissociation, photochemical dissoctiation and dissocitation for electrical discharges.

Question 11

Which reaction is faster?
O+O
O+O2

Answer 11

Second one, because we are forming a single bond, in the first one a double bond.

Question 12

Molecular geometry of O3

Answer 12

Angular or bent with resonance

Question 13

Bond order of O3

Answer 13

1,5

Question 14

Bond of O3?

Answer 14

An intermediate between a single and a double bond.

Question 15

Smell of O3

Answer 15

Intense odor gas

Question 16

Solubility in water of O3

Answer 16

Little soluble

Question 17

What is higher in O3 than in O2?

Answer 17

Melting and boiling point are higher due higher intermolecular forces since O3 is bigger. Also is more unstable, less bond order than O2.

Question 18

Decomposition of O3

Answer 18

Explosive

Question 19

Enthalpy of ionization of O

Answer 19

Really high

Question 20

Which energy will be higher the first ionization energy or the second one of O?

Answer 20

First one

Question 21

Bond order of O2+

Answer 21

2,5
