Mixtures and Compounds

Before I start I find it necessary to inform you that I have found song about everything science related. Putting that out there. So today I want to talk about compounds and mixtures, which you may have guessed if you read the title. Sadly, I didn't find any songs on compounds so you may just have to listen to my boring version. Sorry guys. Let's talk about compounds!

Compounds are when a chemical change takes place, unlike a mixture where a physical change would take place. Let's use water for example. As I mentioned before hand, water is 2 hydrogen atoms and 1 oxygen atom. This is a compound because it is extremely hard to separate. With that being said, compounds look nothing like they're original elements. Salt is another example. What color is salt? I'm gonna pull a Dora the Explorer here and assume you said white. Would you ever guess that green chlorine gas and a silvery medal could make something people enjoy sucking off of pretzels? I know, science is inexplicably amazing. 

Here are some more examples to go by.

I actually have a song for this one! Yay! Mixtures! Here we go.... When two or more elements, or compounds, are blended without combining chemically you have a mixture. Think of it like a salad! If I make a salad with tomatoes, onions, croutons, carrot, chicken, and lettuce, how easy would it be to separate? Exactly. See, each substance in a mixture retains it's own properties. So if you surround a cherry tomato in lettuce, it isn't going to become lettuce, it will stay a tomato. Mixtures can be separated either physically, or mechanically. Video (<<<click the link over there)

So that should should explain somethings... Any who, solids, liquids, and gasses can all be blended into homogeneous or heterogeneous mixtures. Complicated huh? Thought so, we'll use some examples. I trust you have been to a beach before, so let's talk about ocean water. (If you haven't, dude, go outside and live a little please.) The ocean is one giant homogeneous mixture. When you look at salt water do you see white crystals floating in the water? Nope. It's clear. 100% crystal clear. No matter how hard you look you won't see anything. With this type of mixture, it is dissolved into the water.

There ya go, it shows how it works.

You know that salad I mentioned earlier? Well no salad is complete without dressing! Vinegar dressing are a heterogeneous  mixture, which means its parts don't mix completely. Sometimes you can see the oil in the dressing and all of the herbs and spices floating in it.It used to gross me out... Any who, I hope this helped!

Meanwhile, I found a song relating to last weeks topic. Check it out! Atom Structure Song hope you liked it! Comment! -GSalad
