Discussion 1: Discuss how the “law of conservation of mass” is applied in chemistry in terms of balancing of chemical equations.

Discussion 2: When balancing chemical equations, which one do we adjust: “stoichiometry coefficients “(numbers in front of the formulas) or “subscripts” (numbers in the formulas)? Give relevant examples to support your discussion answer.

Discussion 3: Discuss the connection between : “Avogadro’s number and the Mole”.

Discussion 4: Discuss how the three types of chemical reactions discussed in chapter 3 are different in terms of the products formed. (Note: Use equations to support your response).

Discussion 5: Which reactant controls the theoretical yield in a chemical reaction: THE LIMITING REACTANT OR THE EXCESS REACTANT? Discuss in detail using relevant examples.
