Which of the following is an example of a model? PV=nRT, Geographical map, I believe that aliens exist, all of the above.
aleksandrvk [35]

<u>Answer:</u> The correct answer is geographical map.

<u>Explanation:</u>

Model is defined as the three dimensional representation of a proposed structure in a smaller scale.

For the given options:

<u>Option 1:</u>  PV = nRT

This is a proposed law. This law is known as ideal gas law. A law is defined as the rule which defined a correct procedure. For any gas behaving ideally, this law is used.

<u>Option 2:</u> Geographical map

Map is defined as the diagrammatic representation of an area of land or sea which also shows physical features, roads, cities etc..

A 3-D model can be prepared for geographical map.

<u>Option 3:</u> I believe that aliens exist

This is a hypothetical statement. It is a smart guess by the means of set of assumptions and observations. For its validation, we need to conduct some experiments.

Hence, the correct answer is geographical map.

Choose the atom with:
nata0808 [166]

Answer:

a )Li

b)O

c)F

Explanation:

a) Li-1s^2 2s^1

F-1s^2 2s^2 2p^5

it is easy to pull out e- from 2p orbit than 2s because 2s orbit is close to nucleus.Therefore Li have high ionisation enthalpy

b)oxygen ion is larger than Na because o have fewer proton

c)F because it requires only 1e to achieve stable noble gas configuration.Therefore to achieve stable nobke gas electonic configuration it accept 1e.
