okay so today what we're going to do a compound mixture station lab so are essential question reason why we're taking these nose is how is matter classified based on it question number 1 what is matter matter so what is a pure substance that is the other property next week a physical property so physical properties of what they physically or like their color chemical properties are how they chemically react are they flammable physical property question is what is syphilis are there you're talking about parts of a now so elements are the purest smallest form of matter 108 elements on the periodic table periodic table one or two letters only for it to be announced symbol is a capital letter and lowercase so this is one Element this is one Element question for what is a diatomic element it's still considered an element which always together diatomic elements and the way you cannot remember this is I have no bright or clever friends now a diatomic element element is is why don't you just plate to section so it's hydrogen Hy nitrogen Virginia this one here is chlorine chlorine topic question 5 what is matter that is composed of more pound of pure substances that are made of two or more elements chemically bonded together what is a compound word like butterfly baseball two different small together if you put two of the same or together butter butter butter is not a word butterfly calcium carbonate carbon element is a third element three different elements hey there's one carbon to oxygen element chemically bonded together different capital letters the individual elements in it at room temperature is a gas remember it's a gas at room temperature Gmod so for instance if you put call MCL together and ACL or sodium chloride I want you to do a circle each element symbol with a different color in the above right select start circling the first color with two blue for in a which is sodium so here is a sodium hydrogen doing rain can you shred again Magento usual lunch that makes water sugar is made up of carbon hydrogen and oxygen your three different types of elements sodium and chlorine question number 6 what is matter that is composed of more than one substance either called mixtures not chemically combined there are only physically combined properties because the new stuff substance is not and there are two types of mixtures there are homogeneous mixtures the prefix homo or similar and it looks like just one thing when it's actually a bunch of different things sugar water and the Cheetahs actually mixed together but there is actually carbon nitrogen in a bunch of other stuff mixed together think about here in Virginia versus are New York City New York City actually copper and zinc mixed together but it looks like it's made of one metal do you have a homogeneous mixture is known as a solution another type is called a heterogeneous mixture 360 I mean two different things mixed up they don't stay separated another example of that is Cowboys milk eventually if you let milk sit out it will separate into a different car catch up milk takes a long time to settle out they will eventually settle into different life example is salad dressing dressing the bottle such as like Italian salad dressing I want you to element likely the word diatomic a little bit darker blue and mixtures talk about elements in the red that you colored in the word element on the periodic table properties next time you are two or more properties are different than individual elements chemical formula if you take blue and red you get purple so do this one in purple considered pure substances pictures are not yellow it's two or more substances that are not things look differently they said they'll never settle out or more different substances are different types of atoms physically mixed together what do all three have in common the mixtures have in common that they don't have what you're going to do on the very very put them in your diagram hey need to do number two have a great rest of the day
