  1. DOUBLE REPLACEMENT • A LABORATORY EXAMINATION OF DOUBLE REPLACEMENT REACTION www.assignmentpoint.com

  2. SAFETY • GOGGLES • HAIR TIED BACK • APRONS www.assignmentpoint.com

  3. CHEMICAL THEORY • THERE ARE MANY TYPES DOUBLE REPLACEMENT REACTIONS, SUCH AS ACID-BASE NEUTRALIZATION AND PRECIPITATION. www.assignmentpoint.com

  4. PRECIPITATE REACTIONS • THESE ARE REACTIONS IN WHICH AN INSOLUBLE SOLID IS FORMED AND SETTLES OUT OF SOLUTION, THE PRECIPITATE. www.assignmentpoint.com

  5. EXAMPLE/FORM EQUATION • AB + CD ----> AD + CB • THE CATIONS “TRADE” PLACES www.assignmentpoint.com

  6. THE REACTION • WRITE THE BALANCED REACTION: • CaCl2(aq) + Na2CO3(aq) -----> 2NaCl(aq) + CaCO3(s) www.assignmentpoint.com

  7. MATERIALS • RINGSTAND/WIRE TRIANGLE • FUNNEL • # 1 WHATMAN FILTER PAPER www.assignmentpoint.com

  8. MATERIALS • ASSORTED BEAKERS • ASSORTED FLASKS • GLASS STIRRING ROD • DRYING OVEN www.assignmentpoint.com

  9. REAGENTS • Na2CO3 SODIUM CARBONATE • CaCl2 CALCIUM CHLORIDE www.assignmentpoint.com

  10. PROCEDURE • ADD 1 GRAM OF EACH “SALT” TO 20 mL OF WATER IN TWO SEPARATE BEAKERS AND DISSOLVE, THEN MIX SOLUTIONS IN COMMON BEAKER www.assignmentpoint.com

  11. PROCEDURE CONTINUED • POUR THE CONTENTS OF THE BEAKER THROUGH THE FILTER PAPER FUNNEL ASSEMBLY www.assignmentpoint.com

  12. MORE PROCEDURE • REMEMBER, PRE-MASS THE DRY FILTER PAPER BEFORE FILTERING www.assignmentpoint.com

  13. DATA AND CONCLUSIONS • CONSTRUCT A DATA TABLE • DESCRIBE WHY THE LAB RESULTS OCCURRED IN CONCLUSION • CALCULATE THEORETICAL YIELD, THEN PERCENT YIELD AND PERCENT ERROR www.assignmentpoint.com

  14. TECHNICAL WRITING PORTFOLIO • WRITING FOR A SPECIFIC PURPOSE • NO FLOWERY PROSE, GET TO THE POINT • MATH IS A LANGUAGE, CALCULATIONS ARE VITAL TO WRITEUP www.assignmentpoint.com

  15. PURPOSE • WRITING TO INFORM, MAKE A DECISION OR LEARN HOW TO DO SOMETHING www.assignmentpoint.com

  16. AUDIENCE • TARGET A SPECIFIC GROUP • OUR GROUP IS MIXED AUDIENCE, IF YOU CAN WRITE DIRECTIONS TO PUT A SWING SET TOGETHER YOU CAN WRITE ANYTHING www.assignmentpoint.com

  17. ORGANIZATION • WE WILL FOLLOW THE PROBLEM, CAUSE, SOLUTION FORMAT • THIS LENDS ITSELF TO THE LABORATORY ORGANIZATION www.assignmentpoint.com

  18. WRITING • CHOOSE THE DETAIL, AMOUNT OF DESCRIPITION • GRAPHICS ENHANCE THE IMPACT OF A PAPER www.assignmentpoint.com

  19. COMPONENTS • TITLE. TO THE POINT, DESCRIPTIVE OF THE LAB. • INTRODUCTION. STATES CLEARLY THE QUESTION/PROBLEM AND WHY LAB WAS PERFORMED • EXPERIMENTAL DETAILS/RESULTS: EXPLAINS WHAT YOU DID AND WHY, AND LISTS RESULTS www.assignmentpoint.com

  20. MORE COMPONENTS • CONCLUSIONS & DISCUSSION ANALYZE THE RESULTS AND EXPLAIN WHAT HAPPENED IN THE LAB • EXTENSIONS: “REAL WORLD” USES OF THIS REACTION AND LIME www.assignmentpoint.com

  21. STILL MORE COMPONENTS • ACKNOWLEDGMENTS. LIST WHO CONTRIBUTED TO THE COMPLETION OF THE LAB • REFERENCES. LIST ANY TEXTS OR MATERIAL USED IN THE WRITING OF YOUR PAPER www.assignmentpoint.com

  22. NUTS & BOLTS • PAPER IN BLUE OR BLACK INK OR WORD PROCESSED • FRONT OF PAPER ONLY • TITLE PAGE • DRAWINGS/ILLUSTRATIONS REQUIRED • GOALPOSTS, GOALPOSTS, GOALPOSTS www.assignmentpoint.com
