Here are the answer (in order) for [[Questions from Chem328MatterGeneralInformation Video]]:<br> <br> 1a) Mixture - more than one type of particle (base unit)<br> 1b) Pure Substance - ONLY one type of particle (base unit)<br> <br> 2a) Two mixtures : Heterogeneous and Homogeneous<br> 2b) Two substances: Element and compound<br> <br> 3a) Chocolate chip ice cream and vanilla ice cream<br> 3b) Argon (Ar) and Carbon dioxide (chemical formula is C<sub>1</sub>O<sub>2</sub>)<br> <br> <br> 4) Two or more elements chemical combined in a fixed mass ratio. Carbon monoxide (chemical formula is C<sub>1</sub>O<sub>1</sub>)<br> <br> 5) Heterogeneous mixture have their different particles (components) UNEVENLY distributed while Homogeneous mixtures have their different particles EVENLY distributed.<br> <br> 6a) Colloid and 6b) Suspensions. Their different components DO NOT settle out (colloid) while suspensions different particles DO settle out.<br> <Br> 7) Tyndal Effect occurs when the particle aggregate together in such a large group that it affects light passing by the group. Heterogeneous mixture have Tyndal Effect and Homogeneous mixtures DO NOT.<br> <br> 8) Homogeneous mixture<br> <br> 9a)Separation : techniques are different<br> 9b)Properties of substances that make it up ARE different from the resulting material properties (compound) or NOT (mixture).<br> 9c) Composition: One is fixed (compound) and one can vary (mixture)<br> <br>
