Well, more of a reason to look forward to high school chem I guess. Hopefully you get an awesome teacher like mine.

Well, if you know all this, you'll easily pass school. I don't even know this stuff! This suff is like grade 10!!!

I'm going to homeschool. Learning all by myself without any teachers

Aww thanks!
I'm learning it online, that's why. The web is quite helpful.

[ThatGamer]

Just like I did for 9 years! 

Too bad I'm done homeschooling this year...I really enjoyed it...

Hey, maybe if you end up not liking homeschooling, you could try online schooling? Another good way to get education! (though you do get a teacher...)

That's a good idea! I'm sure you enjoyed it very much and I think homeschool will work fine.

Warning:Unfortunately, I will be posting quite a few questions in a short amount of time.

Alright, so it says write E for elements, C for the compounds, and M for the mixtures. Please tell me if I'm wrong.

Water: I did it as elements because I know that water is Hydrogen and Oxygen and they are both elements, so this is an element.
Wine: Hmmm. This one was tough. What exactly is wine made of? I'm guessing since water and wine are beverages, wine is made of elements, so I choose elements.
Soil: I think it's a mixture because when I touch the soil it feels soft like pancake mix, and that's mixture, so I choose mixture.
Silver: Element because I know silver is in the Periodic Table.
Aluminum oxide: I know aluminum is an element, so I'm going to say element, though there is oxide and I have no idea what that is.
Hydrogen: Element, easy, we talked about this yesterday.
Carbon Dioxide: Element because carbon is an element. No idea what dioxide is though.
Air: The air is an element because of the oxygen.
Hydrochloric acid: Toughie. Hmmmm, I honestly have no idea because of the word acid. I feel like acid is a mixture of elements.
Nitrogen: Element.
Tin: Element.
Potassium Chloride: Again, no idea what the chloride is, but since potassium is an element, element.

I'm sure it will work for you too!

For the elements, they mean a pure element. Compounds are combinations of elements that have bonded, so water is a compound. Things like Carbon Dioxide are also compounds, di means two, so it's a carbon and two oxygens bonded.

Water is not an element, it's a compound. Compounds are combinations of more than one element that bond together.
Wine is a mixture. It has alcohol in it, I'm sure it has sugar in it, it probably has plenty of water in it. Mixtures are just that: mixtures of different compounds or elements that don't actually bond, they're just near each other. Like if you took sand and mixed it in with sugar.


Soil is a mixture, yes.
Aluminum Oxide is a compound. It's Aluminum ionically bonded to Oxygen: Al2O3
Hydrogen is an element, yes. Although Hydrogen GAS (H2) is a compound.
Carbon Dioxide is a compound. CO2.
Air is a mixture of gases, most notably Nitrogen and Oxygen, but also some other stuff.
Hydrochloric Acid is a compound. HCl. It's Hydrogen and Chlorine.
Nitrogen, once again, is an element. However, Nitrogen GAS (N2) is a compound.
Tin is an element.
Potassium Chloride is KCl, or Potassium bonded to Chlorine. It's a compound.

Thanks guys!

Morale of today: Compounds are two or more elements that are bonded and mixture is 2 or more elements mixed together, but not bonded. Mixtures can also be compounds mixed together, or with solid particles.

Thanks guys! chapter 1 is complete!

Congrats, you just passed grade 9 science! Lol

[mayastarr041]

Congrats, you just passed grade 9 science! Lol

YAY!
Though it's only the beginning.

[ThatGamer]

YAY!
Though it's only the beginning.

Yeah. Though that is an important factor of grade 9, you still need to learn more...

[Hero of Trains]

Yeah, another thing, mixtures can also be compounds mixed together, or with solid particles.
