Main focus: 

1. To Review the CAT 2 – Classification of Matter quiz

2. To Identify and classify matter from chemical formulas

3. To identify the properties of a mixture as compared to a compound

Standard 4 – Performance Indicator 3.1- 

Explain the properties of materials in terms of the arrangement and properties of the atoms that compose them.

3.1q -Matter is classified as a pure substance or as a mixture of substances.

3.1r – A pure substance(element or compound) has a constant composition and constant properties throughout a given sample, and from sample to sample.

3.1s -Mixtures are composed of two or more different substances that can be separated by physical means. When different substances are mixed together, a homogeneous or heterogeneous mixture is formed.

3.1t – The proportions of components in a mixture can be varied. Each component in a mixture retains its original properties and 3.1u ,3.1w, 3.1x, 3.1cc, 3.1dd,   

Period  6: 

1. Review of Last Friday’s Quiz.

CAT 2 KEY – Lecture 1.9 – 22-23.pdf                                                                                                                View Download 

2.  Revisit the Elements Compounds Mixtures OH my activity sheet.  WE will continue identify how compounds and mixtures differ by using this key.

 Compounds are always prepared chemically separated chemically! 

 

– as a result the individual components of a compound (elements) lose their individual properties and when they bond to form a compound. 

 

 Example:  Sulfur and Iron separation of a Magnet Vs. Pyrite.

     

Mixtures are always prepared physically and separated physically!

   

– as a result the substances in a mixture ALWAYS KEEP THEIR individual properties in a mixture.

– which means that they can be separated bases on their individual PHYSICAL Intensive PROPERTIES. 

 

 Example:  Distillation of Coke

 

3. Separation techniques for mixtures: Distillation, Filtration, evaporation, Chromatography 

 

– Chromatography Demo – Column and TLC. 

 

 

 

Period  7:
