1.1 Stoichiometry: Particle Nature of Matter & Chemical Change

08 /09 /14

*Atomic Theory Test was done today*
*Notes from Youtube Video*

Particle Theory

• All matter is made up of particles 
• Particles have kinetic energy (above 0 K)

Phase Changes

• Solid - particles are packed together forming rigid shape
• Liquid - particles can move a bit more freely creating a substance that flows (takes shape of container)
• Gas - particles have free movement & fill entire volume of container
• Melting = solid  →liquid
• Freezing = liquid → solid
• Vaporization = liquid → gas
• Condensation = gas  → liquid
• Sublimation = Solid → gas
• Deposition = gas  → solid     

Combining Powers: using charts below

• Simple binary compound (ex. Calcium fluoride)
• Transition Metal Compound (ex. Titanium IV oxide)
• Compound ions (ex. Lithium sulfate)

Balancing Equations

1. Write symbols for chemicals being used
2. Balance - have same number of atoms on each side of equation
3. State symbols (s, g, l, aq)
