Do the following problems in your textbook: Page 875, Ch 10 problems # 1-15.
Ch. 10 TEST is Tuesday 12/12. You should be able to: Identify a reaction's type from just the reactants, and predict what the products will be; Write the correct chemical formulas for the reactants and products; Balance the equation; Use the Activity Series (aka hotness scale) or solubility chart to determine if single- or double-replacement reactions will occur, and identify which product of double replacement will be the precipitate. The activity series and solubility charts will be given to you.

Assignment
Complete # 11-30 on the reactions printout. In addition to writing the balanced equation for each reaction, also identify each reaction type (C, D, S, SR, or DR). For reactions that qualify as more than one type, list both. Refer to the "hotness scale" on page 288 or the solubility table on page 920 as needed.

Balance the first 25 reactions on the attached worksheet. Your final answer should not use fractions as coefficients, and you cannot change, remove, or add subscripts or formulas!
RETAKE opportunity for polyatomic ion quiz today! Please note the following:
This quiz is OPTIONAL
This quiz will cover ALL 30 ions
This quiz will be weighted to 20 points (same as the first ion quiz)
Whatever score you get on this quiz will be the one recorded for you, even if it's worse than your first score! This is not a "best of" or "score averaged" quiz!
