1. An Element

A good example of a household element is found inside of a battery; Lithium. 

2. A Heterogeneous Mixture

Dirty water is an example of a heterogeneous mixture, because it can easily be seperated. 

3. A Homogeneous Mixture

Gatorade is an example of a homogeneous mixture, because it is impossible to seperate using a simple procedure, such as filtration.  

12. A Mixture that can be seperated by filtration

This dirt and water mixture is an example of this, because if you used a filter, the dirt would easily seperate from the water, leaving you with two different substances sperated from one another- Dirt And Water. 

13. A Mixture That Can Be Seperated By Other Methods Than Filtration

This is an example, because if you ran this koolaid-water mixture through a filter, it would not seperate into two seperate substances- koolaid powder and water.  

14. A Substance With Density Less Than 1g.

I used the water displacement method, using a graduated cylinder, to determine that this pencil eraser's density is around roughly .6g- which is less than 1.  

15. A Substance With Density More Than 1

I used the mater displacement method on this dime, and found out that its density was around 8g, which is more than 1.  

18. A Metal

This paperclip, like many others, is made of a kind of steel, which is a metal.  

19. A Non-Metal

This toothpick is not made of a metal of any kind, it is in fact made of wood, like many of its kind.  

25. A Mole Of Water

The amount of water I have presented here is nearly equivilant to a mole, because:

1 ounce=roughly 28g

1 mol= roughly 18g

So,

1 mole is around .67 ounces 

30. Magnesium Sulfate

This Eposm Salt, used for soothing some injuries, is infact 100% Magnesium Sulfate.
