Visual Check
- To predict solubilities and describe solubility situations
- To graph energy exchange in a chemical reaction
In-class Examples and Practice For Balancing Equations and Solubility
The final assessment for this unit requires equations to be balanced three different ways:
Balancing based on Conservation of Mass
Balancing based on elements shown
Balancing based on visual models

Skeptical Questions In Science
The skeptical question topic for this unit involves the topic of "conspiracy theories in science". Skeptical questions are thoughtful "Why-based" questions which address biases in scientific material. This type of question is not seeking scientific facts.

This is where 80% Quiz #1 will occur for Unit 6. This quiz includes balancing reactions for Conservation of Mass and numbers of elements or polyatomics. The reaction must also be balanced in a visual manner.
Hindenburg Intro Lab and Reflection
The Hindenburg Intro Lab is an opportunity to look at a basic chemical reaction and analyze products and reactants for solubilities.
Solubility Rules and Curves
Solubility Rules and Curves are tools used in Chemistry to determine what "form" an element or compound will typically take in a chemical reaction. Solubility Rules base that form on the materials in a compound. Solubility Curves indicate the way the form is influenced by temperature. The following are the reference pages and practice sheets used for solubility.
Solubility Forms Used in Chemistry 11
(s) - Insoluble solid
(aq) - Soluble aqueous solution
(l) - Liquid
(g) - Gas
The Solubility Reference Pages, Practice Without Reactions, and Practice With Reactions are shown here. The same practice sheets used for balancing are also used for solubility practice with reactions.

Balancing and Solubility Answers.pdfBalancing and Solubility for Chemical Reactions.pdfCollision Theory and Reaction Energy
Chemical reactions occur for a number of reasons. The main three reasons are
Random collisions form new particles which can rearrange to form new compounds
Particles and compounds are attempting to achieve a more stable energy state
Particles and compounds are attempting to achieve a more stable electron structure
Collision Theory and Energy Exchange Answers.pdfMg + HCl Reaction Full Lab
The purpose of this full lab is to analyze a chemical reaction for both solubility products and heat exchange. The reaction used is another form of the "Hindenburg Reaction" or hydrogen producing reaction. Most reactions involving metals and strong acids tend to produce hydrogen as a product.
