2 or more elements mixed together

Question 10

What Is A Mechnical/heterogenerouse mixture

Answer 10

a mixture where you can see all the elements in it

Question 11

What Is A Solution/homogenerous mixture

Answer 11

a mixture that only looks like one element

Question 12

How are particles arrange in A Liquid

Answer 12

a little more spread out than a solid

Question 12

How are particles arrange in A Solid

Answer 12

very close and tight

Question 13

How are particles arrange in A Gas

Answer 13

very spaced out compared to a solid or liquid

Question 14

How are particles arrange in a Soloution

Answer 14

All the particles are mixed together as one

Question 15

How are particles arrange in A Pure Substance

Answer 15

All the same particles together as one

Question 16

How are particles arrange in A Mechnical Mixture

Answer 16

All the kinds of particles with the same kind of particle

Question 17

What are the five main ideas or particle theory

Answer 17

1.all matter is made up of tiny particles, 2. particles have empty spaces in between them, 3. particles are always moving, 4. the faster and more spread out the particles are the hotter they are, 5. particles attract each other so they are closer together

Question 18

List,compare and contrast solids,liquids and gases

Answer 18

a solid has tighter particles, a liquid has loose particles, and a gas has extremely loose particles

Question 19

Give an example of a solid,liquid and gas

Answer 19

Cup, Water, Nitrogyn

Question 20

What is the difference between the solid particles and the gas particles:

Answer 20

Solid particles are very tight while gas particles are extremely loose

Question 21

What is the difference between a pure substance and particles of mixture

Answer 21

A pure substance only has the particle of one element & the particles are all mixed together while the particles of a mixture are 2 or more elements mixed together

Question 21

What is the difference between a pure substance and particles of mixture

Answer 21

Yes it is

Question 22

Is tap water a pure substance

Answer 22

it is a mixture because it contains chemicals and filters in it

Question 23

How is a mechnical mixture diffrent from a soloution

Answer 23

in a solution it only looks like one element however in a mechanical mixture it looks like more than one element

Question 24

Is A fruit salad A Soloution or a mechnical mixture

Question 25

Is oil and vinager salad dressing A Soloution or a mechnical mixture

Question 25

Is clear hand soap A Soloution or a mechnical mixture

Question 26

List two drinkable soloutions

Answer 26

Juice/Milk

Question 27

Use particle theory to explain the parts of a mechnical mixture

Answer 27

a mechanical mixture is made up of particles, they have empty spaces in between them, the more spred out the mixture it is the faster it’s moving the particles in the mixture are not close together

Question 28

What's the difference between the arrangement of particles between a mechanical mixture and a particle of solution

Answer 28

in a mechanical mixture the particles are near the same type of particles they are but in a solution all the different particles are mixed together

Question 29

What are 3 things wood, a bowl and salad all have in common

Answer 29

there all solids and are all mechanical mixtures

Question 30

Use particle theory to explain why a ballon expands when it heats up

Answer 30

when a balloon gets warm it expands because the heat allows the particles to move faster and make them expand

Question 31

When an ice cube melts do it's particles change

Answer 31

yes it does because the particles move faster when they melt due to the fact they are turning from solids to liquids

Question 32

Is orange juice pulp a solution or a mechanical mixture. Why or why not

Answer 32

they are a mechanical mixture because you can pick them out in a glass of juice

Question 33

Can you tell if a liquid is a solution or a pure substance by looking at it? Why or why not

Answer 33

yes you can because if it were a michnical mixture you would see all of it and if it was a mixture you would see only one part of it

Question 34

Would a parkora be a mechanical mixture or a solution

Answer 34

a mechanical mixture because you can see every part of a parkora

Question 35

Can a mechanical mixture be both solids and liquids

Answer 35

i think it can be both a solid and a liquid because you would see both the solid and liquid part f it
