GOGGLES
HAIR TIED BACK
APRONS


Слайд 3CHEMICAL THEORY
THERE ARE MANY TYPES DOUBLE REPLACEMENT REACTIONS, SUCH AS ACID-BASE

NEUTRALIZATION AND PRECIPITATION.

Слайд 4PRECIPITATE REACTIONS
THESE ARE REACTIONS IN WHICH AN INSOLUBLE SOLID IS FORMED

AND SETTLES OUT OF SOLUTION, THE PRECIPITATE.

Слайд 5EXAMPLE/FORM EQUATION
AB + CD ----> AD + CB

THE CATIONS “TRADE” PLACES


Слайд 6THE REACTION
WRITE THE BALANCED REACTION:
CaCl2(aq) + Na2CO3(aq) -----> 2NaCl(aq) + CaCO3(s)

Слайд 12MORE PROCEDURE

REMEMBER, PRE-MASS THE DRY FILTER PAPER BEFORE FILTERING


Слайд 13DATA AND CONCLUSIONS
CONSTRUCT A DATA TABLE
DESCRIBE WHY THE LAB RESULTS

OCCURRED IN CONCLUSION

Слайд 14TECHNICAL WRITING PORTFOLIO
WRITING FOR A SPECIFIC PURPOSE
NO FLOWERY PROSE, GET TO

THE POINT
MATH IS A LANGUAGE, CALCULATIONS ARE VITAL TO WRITEUP

Слайд 15PURPOSE
