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.
