What observations are made when experimenting with dry ice?
When handling dry ice, wear gloves.
Goggles are needed during some experiments.
Do not close the transfer container completely.
Analysis of a Mixture
If the mixture is separated, can I find the percent composition of each component in the mixture?
Which processes will be needed to separate these mixtures? Is the mixture homogeneous?
I will wear googles.
Functions and Variables
What relationship exists between mass percent and density?
Solutions can be discarded down the sink. Solids or saturated mixtures can be dumped in the
trash. Goggles are not needed.
What is the mass percent of the H2O in the hydrate compound? How many molecules of H2O are
Solutions can be discarded down the sink. Solids can be dumped in the trash. Goggles are
What type of reaction occurs when MgSO4 as a solid compound is dissolved in water? Is there a
relationship between grams used and heat?
Solutions can be discarded down the sink. Goggles must be worn.
How do the chemical reactions demonstrate Hess Law?
Goggles must be worn. Caution should be exercised when handling acids and bases. Waste
should be given to Dr. J to neutralize.

Laboratory Techniques and Measurements
In this lab we will be measuring the length of various objects, measuring the
temperature of water in different heat settings, and measuring the mass of six
different objects and converting t
This lab will show how freezing or heating a pure substance can be affected by
adding a solution. Osmotic pressure will also be discussed and how the substance
inside the tubing can be measure through the pr
Observation of Chemical and Physical Changes
This lab will be measuring different chemical and physical changes between various
solutions and materials. We will also look at the heating and burning qualities of
material and the di
Separation of a Mixture of Solids
This lab will be exploring the use of heat, cold, magnetic force, and evaporation to
separate a mixture of solids in order to measure the individual weight of each solid
within the mixture.
In this lab we will be looking at each number value and the context of the sentence
to make an educated guess on the proper unit of measurement for the value in
question. We will also discuss the importance of labeling measu
