Convert word equations into chemical equations. It gives plenty of examples and practice problems. This chemistry video tutorial explains how to write chemical equations from word descriptions.
The intermediate product of dinitrogen dioxide N 2 O 2 does not appear in the net reaction but it is involved in the mechanism of the reaction and hence a mathematical model of the reaction must take the presence of N 2 O 2 into account. Do this by determining the lowest common multiple of the two valencies. Select the chemical formula cells and then click Kutools Text Subscript Numbers in Chemical Formulas.
