Unit 8: Reactions
... If you are given the names in your equation, the steps for writing a chemical equation are as follows: 1. Balance the Equation: i. Write in PENCIL (you’ll make mistakes; we all do!); ii. Write the coefficients in one element at a time; iii. You may only add coefficients; you may NOT change any chemi ...

... Two compounds react to form two new compounds. All double replacement reactions must have a "driving force" that removes a pair of ions from solution. Ions in a precipitation reaction will keep their same charges as reactants and products. Formation of a precipitate: A precipitate is an insoluble su ...
