Essential Standards and Clarifying Objectives:
Chm. 2.2 Analyze chemical
reactions in terms of quantities, product formation, and energy.
2.2.2 Analyze the evidence
of chemical change.
•
Product testing - Know the tests for some common products such as
oxygen, water, hydrogen and carbon dioxide: burning splint for oxygen, hydrogen
or carbon dioxide, and lime water for carbon dioxide. Include knowledge and
application of appropriate safety precautions.
2.2.3 Analyze the law of
conservation of matter and how it applies to various types of chemical
equations.
•
Write and balance chemical equations predicting product(s) in a
reaction using the reference tables.
•
Identify acid-base neutralization as double replacement.
•
Write and balance ionic equations.
•
Recognize that hydrocarbons (C,H molecule) and other molecules containing
C, H, and O burn completely in oxygen to produce CO2 and water
vapor.
•
Use reference table rules to predict products for all types of
reactions to show the conservation of mass.
•
Use activity series to predict whether a single replacement
reaction will take place.
