Question: For the hydrate Copper (II) Sulphate, what is the coefficient for water? i.e.)
CuSO4 _ H2O
Max: The coefficient for water is 5 (CuSO 4 5 H2O).
Phil: The coefficient for water will be 8
Ch 1 Chem. Study Notes
Chemistry is the study of matter.
Matter is composed of subatomic particles which interact with each other.
Metal: an element that is a conductor of electricity, malleable, ductile and lustrous.
- Metals are all solids at S

A. What is a chemical reaction?
- A chemical reaction is a process in which one set of chemical substances (reactants) is
converted into another (products). It involves making and breaking chemical bonds and the
rearrangement of atoms.
Materials: well plate, stirring rod, seven mystery solids
beaker, conductivity tester, distilled water, hot plate, goggles, scoopula,

Ethylene oxide is used mainly as a chemical intermediate in the manufacture of textiles,
detergents, polyurethane foam, antifreeze, solvents, medicinals, adhesives, and other products.
Relatively small amounts of ethylene oxide are used as
Neon was first discovered by Scottish chemist, Sir William Ramsay and
Morris Travers, an English chemist, in 1898. Neon is originally a Greek word,
meaning new. Neon is completely non-toxic and chemically inert, so it has no
threat to the environment.

Kinetic Molecular Theory
1. Gases are made of small particles that are far apart in comparison to their own size.
Because of this individual particles are considered to be points of mass with a zero

Accuracy and Precision
The purpose of this lab is to determine the accuracy and precision of lab equipment. The three main
equipment being tested would be 150 mL beaker, 100 mL graduated cylinder, and the 50 mL burette.
