WebFor example, when hydrogen gas, H 2(g), is burned in the presence of gaseous oxygen, O 2(g), a new substance, liquid water, H 2O(l), forms. The covalent bonds within the H 2 molecules and O 2 molecules break, and new covalent bonds form between oxygen atoms and hydrogen atoms (Figure 7.1). Figure 7.1 The Formation of Water from Hydrogen and ...
