THE STUDY OF LIFE
OVERVIEW: Life first appeared on earth approximately 3.5 billion years ago.
A gradual process of evolution has brought about the vast diversity of life we observe
today. Basic concepts of biology, life and the tools used in bio
Lab Report 58306 Molecular Geometry
This lab is about classifying bonds, drawing Lewis structures, predicting molecular geometry,
constructing three-dimensional models, and determining polarity.
Few elements exist in nature a

The Fundamentals of Calorimetry
Calorimetry measures the heat of solution for two salt compounds commonly used in hot packs
and cold packs. We will perform graphical analysis of the calorimetry data for an endothermic
Lab Report 580310
In this activity, models are used to balance chemical equations and provide an understanding of
the Law of Conservation of Mass. These tools aid in the visualization of the number of atoms
Density is a physical property of matter that is based on mass and volume of the substance. Density is a
another measurement we use to determine the value of an item or mass.
Objectives will be calculating densities of reg
Investigating Chemical Reactions
The common types of chemical reactions are studied and performed in this investigation,
including synthesis, decomposition, single replacement, double replacement, and combustion.
Single Replacement Reaction Stoichiometry and Percent Yield
Stoichiometry enables chemists to calculate quantitative relationships between reactants and products in a
The objective we will be balanci
Ideal Gas Law Constant
We will test the relationship between pressure and the number of moles of gas as described by the
ideal gas law. Specifically, we will generate and collect oxygen gas from the decomposition of

OVERVIEW: Biological chemistry is based upon the study of carbon compounds
basic to living organisms. The study of biological molecules probes into the life
processes and pro vides a basis for the understanding of the phenom
