Flashcards do conjunto (12)
- 1Particles and Mixtures A solution is made when a ******, usually a soluble solid --------, is dissolved into a liquid called a +++++++, typically water.****** = Solute
-------- = Compound
+++++++ = Solvent - 2Particles Give two definitions of an atom.The smallest particle of an element.
Scientists originally thought that atoms could not be split up, but this is not the case. - 3Particles Give two definitions of a molecule.A cluster of non-metal atoms that are chemically bonded together.
The atoms in a molecule are joined by covalent bonds. - 4Particles Give two definitions of an element.A pure substance that is listed on the periodic table and only has one type of atom in it.
Most are metals, a few are semi-metals, and the rest are non-metals. - 5Particles Give two definitions of a compound.A pure substance made from more than one type of element chemically bonded together.
Elements bond in fixed ratios and so can be represented by a chemical formula known as a compound. - 6Particles Give two definitions of a mixture.An impure substance made from different elements or compounds.
Mixtures can usually be separated by physical techniques such as filtering and distillation. - 7Simple Distillation Draw an example of simple distillation.
- 8Simple Distillation Draw an example of what would occur after a simple distillation experiment.
- 9Fractional Distillation Draw an example of fractional distillation.
- 10Fractional Distillation Draw what would occur after a fractional distillation experiment.
- 11Paper Chromatography Draw an example of a Paper Chromatography experiment.
- 12Paper Chromatography Draw what would occur after a Paper Chromatography experiment.
