Glucose ferments to produce ethanol(C 2 H 6 O) and carbon dioxide. Word equation: Chemical equation:

Na 2 O(s) + P 4 O 10 (s)  Na 3 PO 4 (s)

A piece of Silver and copper (II) nitrate solution were produced when silver nitrate solution was reacted with a piece of copper Word equation: Chemical equation:

Predicting Products of Rxns 1) Look at the beginning of the reaction to determine the type (ex: Is it element + cmpd?) 2) Rearrange the elements/compounds based on the type (ex: if it is synthesis then put elements together ) 3) Be sure to balance the charges of ionic compounds using subscripts 4) Then balance the complete equation with coefficients. Remember H 2 O 2 F 2 Br 2 I 2 N 2 Cl 2, S 8 and P 4 Useful website for help: predict.htm predict.htm
