As thermal energy increases and there is more particle movement.

Thermal energy is the energy possessed by the system or object due to the movement of its particles.

For example kinetic energy of the particles
Higher the motion of the particles more will be the thermal energy of the system or object and vice-versa
It is also termed as heat energy of a system or object
The higher the thermal energy, the higher will be the temperature and vice versa.

So, from this, we can conclude that as thermal energy increases and there is more particle movement.

How many grams are in 1.946 moles of nacl

Ilia_Sergeevich [38]

Answer:

113.8g

Explanation:

Statement of problem: mass of 1.946mole of NaCl

Given parameters:

Number of moles of NaCl = 1.946mole

Unknown: mass of NaCl

Solution

To find the mass of NaCl, we apply the concept of moles which expresses the relationship between number of moles and mass according to the equation below:

Number of moles = $\frac{mass}{molar mass}$

To find the molar mass of NaCl:

the atomic mass of Na = 23g

atomic mass of Cl = 35.5g

Molar mass of NaCl = (23 + 35.5) = 58.5gmol⁻¹

Mass of NaCl = Number of moles x molar mass of NaCl

Mass of NaCl = 1.946 x 58.5 = 113.8g

How is the gravitational force related to the distance between two objects?

babunello [35]

The gravitational force is related to the distance between two objects because it is inversely proportional to the square of the distance.

<h3>What is the gravitational force?</h3>

The gravitational force refers to the attraction between two different objects due to their masses.

This force (gravitational force) is fundamental for maintaining the distance of objects in the Universe.

In conclusion, the gravitational force is related to the distance between two objects because it is inversely proportional to the square of the distance.

3. How many moles of silver is 8.46x1024 atoms of<br> silver?

ioda

Answer:

<h2>14.05 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

$n = \frac{N}{L} \\$

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

$n = \frac{8.46 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 14.053156$

We have the final answer as

<h3>14.05 moles</h3>

Hope this helps you
