What is the best method to classify a chemical substance?
Variables
Different classifications of chemical substances
Different types of bonding
risk assessment
Melting or boiling point - the temperature of the substance melting or boiling
Conductivity - a measure of the substances ability to conduct heat or electricity
Covalent Bonding - When two non-metallic atoms combine with the same or different non-metallic atoms.
Metallic Bonding - The electrostatic attraction between conduction electrons and positively charged metal ions.
ionic
Properties
- High melting and boiling point
- conducts electricity
- Mettalic Lattice Structure
IV
Properties - high melting and boiling point, solid, lattice structure, poor conductivity
Properties - low melting and boiling point, poor electrical conductivity, non malleable, brittle
Glass Breaking
beakers
test tubes
substance getting in contact with eyes
causes irritation
redness in eyes
watery eyes
Heat from Bunsen burner
Could catch on the gloves and cause a part of the glove to burn.
The peg being used to hold the test tube might turn black
