Stoichiometry: calculations with chemical formulas and equations iodine method discussed in chem 1201 review/preview session. See section 3. 1 in the text for more information and examples. putting in the correct coefficients. Never change the subscripts to balance an equation: balancing chemical equations: A. memorize the diatomic elements: hydrogen, oxygen, fluorine, chlorine, bromine, Write the correct chemical formula for all compounds using the charge criss-cross. C. make the number of each kind of element the same on both sides of the equation by. Three simple types of reactions are frequently encountered in this chapter: combination (or synthesis) reactions, decomposition reactions, and combustion reactions. An example of each type is shown below: combination (or synthesis) reactions are those in which two or more substances combine to form a larger substance. The general representation of a combination reaction is: a + b (cid:198) c: decomposition reactions are those in which a compound breaks down into two or more simpler substances.
