Why do scientist use models to study atoms

Chemistry

maxonik [38]3 years ago

Scientist use models to study atoms because you cannot either see or perceive directly what do atoms look like.

Models permit to explain in a simplified way how the atoms are constituted, and, so, figure out how they behave and how they are the bulding blocks of the matter (elements and compounds).

A model can be a drawing or structure with balls and sticks, which show in an idealized way what an atom is.

Since the scientists have discovered different facts about the atoms along the last 200 years the models of the atoms have also evolved.

The plum pudding model of the atom proposed by JJ Thompson was different of the nuclear model proposed by Rutherford, and Rutherford's was different from the planetary model proposed by Bohr, and this is different from the quantum model.

Models are used to study atoms because we can never really see an atom up close, and a model is like a super magnified version of the atom. Plus, its easier to study from them because we can pin point the different characteristics of the atom (Protons, Neutrons, etc.)

What is the mass, in grams, of one mole of any substance known as?
Elena-2011 [213]

Answer: molar mass

Explanation:

The molar mass of any substance is it's relative molecular mass expressed in grams. Hence, the relationship between molar mass of any substance and mass, in grams, of one mole of any substance is mathematically expressed as:

Number of moles =

(Mass in grams ➗ Molar mass)

Hence, the unit of molar mass is gram per mole (g/mol)

Thus, molar mass is the answer.

Energy is stored in chemical bonds during photosynthesis.

During photosynthesis, the radiant energy from the sun is converted to chemical energy in carbohydrates.

Inorganic materials in the form of carbon dioxide and oxygen combine to form carbohydrates in the presence of radiant energy according to the equation below:

6CO_2 + 6H_2O ---> C_6H_1_2O_6 + 6O_2

The energy is thus, stored in chemical bonds in the carbohydrate and this is what is oxidized during respiration to release the locked energy.

A compound with chemical formula na2cx3 has formula mass 106 amu .. what is the atomic mass of element x
maria [59]

The element "X" is "O" (oxygen).

<h3>Calculation:</h3>

Given,

Chemical formula = Na₂CX₃

Formula mass = 106 amu

Molar mass of Na = 23 amu

Molar mass of C = 12 amu

To find,

Element X =?

We will equate the equation as follows,

2(23) + 12 + 3(y) = 106

46 + 12 + 3y =106

58 + 3y = 106

3y = 106 - 58

3y = 48

y = 48/3

y = 16

We know that Oxygen has molecular mass of 16. Therefore the element "X" is "O".

What do you use to determine molar mass?
levacccp [35]

Answer:

the molar mass of any element can be determined by finding the atomic mass of the element on the periodic table for example, if the atomic mass of sulfer is 32.066 amu, then it's molar mass is 32.066 g / mol
