Writing Balanced Chemical Equations Important principles: ¾ Every chemical compound has a formula hich cannot be altered which cannot be altered. 9 The state of the compound is usually specified he number of atoms of each type must be the same on ¾ The number of atoms of each type must be the same on both sides of the equation H 2 CO 3 (aq) H 2 O(l) + CO 2 (g) H 2 SO 3 (aq) H 2 O(l) + SO 2 (g) Roy A.
