Claire Drexler P2 Characteristics Used To Identify a Substance 1. We use chemical and physical properties to identify a substance. 2. Examples of physical properties: color‚ smell‚ freezing point‚ and viscosity 3. Examples of chemical properties: heat of combustion‚ PH‚ and electromotive force Physical Properties vs. Chemical Properties 1. Examples of physical properties: density‚ luster‚ and conductivity 2. Examples of chemical properties: reactivity with water‚ PH‚ and heat of combustion

AQA GCSE Chemistry Unit 1 C 1: Fundamental ideas: C 1.1. Atoms‚ elements and compounds: * All substances are made up of atoms. * Elements contain only one atom. * Compounds contain more than one atom. * An atom has a tiny nucleus in its centre‚ surrounded by electrons. C 1.2. Atomic structure: * Atoms are made up of protons‚ neutrons and electrons. * Protons and electrons have equal and opposite electrical charges. Protons are positively charged‚ and electrons are negatively

Qualitative Analysis Lab Report Organic Chemistry Laboratory II ABSTRACT: The purpose of this lab was to separate and purify two unknown compounds‚ one solid and one liquid‚ from an ethereal solution using the techniques of chemically active extraction‚ vacuum filtration‚ simple distillation‚ and recrystallization. Then identifying information was compiled about these unknowns by obtaining experimental melting/boiling point ranges‚ and analyzing IR and proton/carbon NMR spectrums It was determined

2011 Abstract The purpose of this experiment is to isolate the essential oil from eucalyptus leaves as a pure compound; moreover‚ the components of the essential oil‚ camphor and limonene‚ will be then separated using gas chromatography technique‚ identify the components by their retention times‚ and compute for the concentration and percentage content of each component by their peak areas and peak heights. The volatile oil from eucalyptus leaves was isolated with the use of steam distillation setup
