Answer:

A solid's particles are packed closely together. The forces between the particles are strong enough that the particles cannot move freely; they can only vibrate. As a result, a solid has a stable, definite shape and a definite volume. Solids can only change shape under force, as when broken or cut.

Why do solids exist ?

Answer:

Hi, There! Frozen here! I'm here To help :)

<em><u>properties depend on the properties of the atoms that form the solid, on the way those atoms are arranged, and on the forces between them.</u></em>

Explanation:

Here's The Defintion of a Solid

<em>A solid is a sample of matter that retains its shape and density when not confined. The adjective solid describes the state, or condition, of matter having this property</em>

<em>And Here are some Examples↓</em>

<em>Examples of solids are </em>

<em>Wood</em>
<em>Metal</em>
<em>glass</em>
<em>rocks</em>

<em>Hope this helps!</em>

Describe the properties of noble gases. Based on their electronic arrangement, explain whether they can exist alone in nature.

Marizza181 [45]

The properties of noble gases include:

They are nonreactive
They have hight ionisation energy
They have low boiling point
They conduct electricity at low pressure.

The noble gases are those elements that makes up the group 18 of the periodic table.

They are non as the inert gases because they are relatively nonreactive.

According to the electronic arrangement, which is according to how the electrons are arranged on their shells, they can exist alone.

The noble gases are nonreactive, have high ionisation energy and low boiling point because in its electronic arrangement, the outer shell is completely full.

Whats the answer to #11

morpeh [17]

Well, one mole would be considered as 6.02 x 1023 (atoms). Which in the copper form, this would be considered to be as 63.66 grams of copper. Know, by knowing this information, we're now able to figured out the question.

53.3 ÷ (atoms) 6.02 x 1023 ...

Which as a result, we then have 2665 over.

When 711 J of heat is added to a 41.1 g of an unknown metal, the temperature of the metal increases from 22oC to 94oC. Calculate

alekssr [168]

The specific heat capacity of the metal is calculated as follows

heat energy = Mc delta T
heat energy (Q) = (711 j )
m=mass (41.1 g)
c= specific heat capacity =?
delta t = change in temperature( 94 -22=72)

c= Q/m delta T
c=711 j / (41.1 g x72) = 0.240 j/g /k
