| Question | Answer |
|---|---|
| A substance made of only one chemical is called... | A pure substance |
| A substance made of only one atom is called... | An element |
| A substance made up of more than one kind of atom chemical bonded together is called... | A compound |
| A substance made up of two or more elements not bonded together is called... | A mixture |
| A substance made up of two or more compounds not bonded together is called... | A mixture |
| A substance made up of elements and compounds not bonded together is called... | A mixture |
| Is butter a pure substance or a mixture? | Mixture (fats, waters, etc.) |
| Is air a pure substance or a mixture? | Mixture (oxygen, nitrogen, etc.) |
| Is water a pure substance or a mixture? | Pure substance (compound) |
| Is gold foil a pure substance or a mixture? | Pure substance (element) |
| Is glass a pure substance or a mixture? | Pure substance (compound) (but reinforced glass is a mixture w/ boron) |
| Is wood a pure substance or a mixture? | Mixture (fibers and stuff) |
| Is grass a pure substance or a mixture? | Mixture (fibers and stuff) |
| Is carbon an element or a compound? | Element (on periodic table) |
| Is aluminum foil an element or a compound? | Element (on periodic table) |
| Is plastic an element or a compound? | Compound (not on table) |
| Is tin an element or a compound? | Element (on periodic table) |
| Is carbon dioxide an element or a compound? | Compound (carbon + oxygen) |
| Is helium an element or a compound? | Element (on periodic table) |
| Is arsenic an element or a compound? | Element (on periodic table) |
| Is sodium chloride an element or a compound? | Compound (stuff + stuff) |
| What is the difference between a compound and a mixture? | A compound is chemically bonded (shares electrons) while a mixture is not (just atoms crammed in together) |
| Is alphabet soup a pure substance or a homogenous/heterogeneous mixture? | Heterogeneous (you can see the noodles separate) |
| Is salt a pure substance or a homogenous/heterogeneous mixture? | Pure substance (NaCL) (but table salt can be different because of iodine and drying agents) |
| Is concrete a pure substance or a homogenous/heterogeneous mixture? | Homogeneous (concrete w/ rocks is heterogenous though) |
| Is vegetable oil a pure substance or a homogenous/heterogeneous mixture? | Homogeneous (all looks like one thing of syrup) |
| Is air a pure substance or a homogenous/heterogeneous mixture? | Homogeneous (all looks the same except with pollen, etc.) |
| Is paint a pure substance or a homogenous/heterogeneous mixture? | Homogeneous if latex, heterogeneous if oil |
| Is sea water a pure substance or a homogenous/heterogeneous mixture? | Heterogeneous (you can see the sand floating in it) |
| Is granite a pure substance or a homogenous/heterogeneous mixture? | Heterogeneous (that's why it looks all flecked, etc.) |
| Is steel a pure substance or a homogenous/heterogeneous mixture? | Homogeneous (it's an alloy; iron is the element) |
| Is sugar a pure substance or a homogenous/heterogeneous mixture? | Pure substance (it has a formula but I'm not looking it up...) |
| How could a mixture appear homogeneous when you look at it, but actually be heterogeneous? | If it separates over time (settling) when freshly stirred, it may look like one material, but in a few minutes/hours/days it'll look completely different. |
| Which of the types of matter can vary in composition between samples? | Only mixtures can vary, because pure substances, compounds and elements all have the same ratios of elements in order to still be considered part of the original material. |
| What kind of changes can be used to separate mixtures? | Physical |
| What kind of changes can be used to separate compounds? | Chemical |
| What kind of changes can be used to separate elements? | Nuclear |
