Which statement explains why ozone gas, O3, and oxygen gas, O2, have different properties?(1) They are formed from different elements.
(2) They have different molecular structures.
(3) They have different oxidation numbers.
(4) They have different electronegativities.

Answers

Answer 1
Answer:

Answer:

The correct answer is option (2).

Explanation:

Oxygen gas and ozone gas are compounds of oxygen with different molecule arrangement . They both also differ in number of total atoms in their molecules.

Oxygen is made up of two oxygen atoms where as ozone molecule is amde up of three oxygen atoms.

Oxygen = O_2 (Paramagnetic)

Ozone = O_3 (diamagnetic)

Structure of both ozone and oxygen are given the in an image attached.
Answer 2
Answer: It's because they have different molecular structures

What are the three particles of an atom?

Answers

The three particles found in an atom are the protons, neutrons and electrons. Protons have a positive charge. Electrons have negative charge. Lastly, neutrons have no net electrical charge. Protons and neutrons are much heavier than electrons and are located in the center of the atom.

What are two types of electron microscopes, and how do they work?

Answers

Scanning electron microscope (sem):  an electron beam scans the surface of a specimen (coated with gold) that excites electron from the specimen which are detected and translated into an image that is three-dimensional. It is used to study the topography of a specimen

Transmission Electron microscope (TEM):a beam of electrons is passed through a thin section of specimen that is stained with atoms or heavy metals and electromagnets acts as lenses that focus the image onto a screen or film. It is used to study the internal structure of a specimen--cells

True or False: Mechanical weathering is the breakdown or rock by changing its chemical composition.​

Answers

Answer:

False

Explanation:

Mechanical weathering breaks rocks into smaller pieces without changing their composition. Ice wedging and abrasion are two important processes of mechanical weathering. Chemical weathering breaks down rocks by forming new minerals that are stable at the Earth's surface.
