  1. 3 2 4 3 • ___ Al2O3 ___ Al + ___ O2 Mad Minute Review 2 3 2 6 3. ___ Cl2 + ___ BI3 ___ BCl3 + ___I Name the types of reactions for the above reactions as synthesis, decomposition, single replacement, double replacement   1b. ____________________________ 2b. ____________________________ 3b. ____________________________ 1. ___ H3PO4 + ___ Al(NO3)3 ___ AlPO4 + ___HNO3 Double replacement Decomposition Single replacement

  2. Predict the products in the following reactions; don’t forget charges! Mad Minute Review Single Replacement 4. Br2+ Mg3N2 First thing you need to do is figure out what type of reaction this is…

  3. Predict the products in the following reactions; don’t forget charges! Hint: when elements are put together… YOU MUST USE CHARGES FIRST!! (before you balance the equation!) Mad Minute Review 4. Br2 + Mg3N2 MgBr2 + N2 A + BC  BA + C Then, you need to use the template as a guide to write the formulas for the products

  4. Predict the products in the following reactions; don’t forget charges! Mad Minute Review Double replacement 5. Ca(C2H3O2) 2+ Ag2S  Figure out what type of reaction this is…

  5. Predict the products in the following reactions; don’t forget charges! Mad Minute Review 5. Ca(C2H3O2) 2+ Ag2S  CaS + AgC2H3O2 AB + CD  AD + CB Hint: when elements are together… YOU MUST USE CHARGES FIRST!! Then, use the template as a guide to write the formulas for the products

  6. Predict the products in the following reactions; don’t forget charges! Mad Minute Review 6. Fe2S3 Decomposition Figure out what type of reaction this is…

  7. Predict the products in the following reactions; don’t forget charges! Mad Minute Review 6. Fe2S3 Fe + S AB  A B Hint: when elements are alone… YOU MUST CHECK IF IT IS A SOLID, LIQUID, OR GAS at room temperature!!

  8. Predict the products in the following reactions; don’t forget charges! Mad Minute Review 3 3 3. __ Br2+ __ Mg3N2 __ MgBr2 + __ N2 Balance the Chemical Equation

  9. Predict the products in the following reactions; don’t forget charges! Mad Minute Review 2 5. __ Ca(C2H3O2)2+ __ Ag2S  __ CaS + __ AgC2H3O2 Balance the Chemical Equation

  10. Predict the products in the following reactions; don’t forget charges! Mad Minute Review 2 3 6. __ Fe2S3 __ Fe + __ S Balance the chemical reaction

  11. Which products (if any) precipitated out in #5? Mad Minute Review You need to use the solubility chart (on the back of your ion sheet! AgC2H3O2 look up acetate in column 1. Read across… is Silver in column 2 or column 3? column 2 = soluble (dissolves) = solution column 3 = insoluble (becomes solid = precipitate out!) Ag = column 3 => precipitate (ppt)

  12. Which products (if any) precipitated out in #5? Mad Minute Review You need to use the solubility chart (on the back of your ion sheet! CaS look up sulfide in column 1. Read across… is Calcium in column 2 or column 3? column 2 = soluble (dissolves) column 3 = insoluble (becomes solid = precipitate out!) Ca = column 2 => stays in solution

  13. How many molecules of gold (III) chloride are in 475 g? Mad Minute Review X mc = 475 g 6.02 x 1023mc g 303.32 gold (III) chloride = AuCl3 AuCl3 = 303.32 g X = 9.43 x 1023 mc

  14. How many grams of ammonium oxide are in 0.874 moles? Mad Minute Review X g = 0.874 moles g 1 mole 52.1 Ammonium oxide = (NH4)2O (NH4)2O = 52.1 g X = 45.5 g
