Elements COmpounds Mixtures
Question | Answer |
---|---|
What are mixtures? | Mixtures are two elements or compounds physically intergrated together |
What are compounds? | Compounds are two or more elements chemically intergrated together |
What are elements? | Elements are 1 element that cannot by broken by chemical or physical ways |
What are the different types of mixtures? | Colloids and Suspension |
How do they differ? | Colloids allow light through. Suspension do not allow light through. |
What are the properties of elements? | consists of only one kind of atom, cannot be broken down into a simpler type of matter by either physical or chemical means, and can exist as either atoms (e.g. argon) or molecules (e.g., nitrogen). |
What are the properties of mixtures? | consists of two or more different elements and/or compounds physically intermingled, can be separated into its components by physical means, andoften retains many of the properties of its components. |
What are the properties of compounds? | consists of atoms of two or more different elements bound together, can be broken down into a simpler type of matter (elements) by chemical means (but not by physical means), has properties that are different from its component elements, andalways conta |
Why do colloids allow light through? | Their particles are big enough to allow light to let light shine in. |
How are they all different from each other? | Elements are pure substances. Compounds are chemically combined elements. Mixtures are physically combined elements. |
What are solutions? | are groups of molecules that are mixed and evenly distributed in a system. |
What is the name for homogenous mixture? | any mixture that is uniform in composition throughout |
What is the name for heterogenous mixture? | simply any mixture that is not uniform in composition |
Why are they important? | Because they are formations of compounds and mixtures |
What are examples of these? | Fruit Loops,bowl of different peanuts- Heterogeneous Water blood plasma-Homogeneous |
