Let's analyze each chemical equation provided:<br /><br />a) $NO_{2}+H_{2}O+O2\rightarrow HNO3$<br />This equation is not balanced. The correct balanced equation should be:<br />$3NO_{2}+H_{2}O\rightarrow 2HNO3+NO$<br /><br />b) $Al_{2}O_{3}+SO_{3}\rightarrow Al_{2}(SO_{4})_{3}$<br />This equation is balanced.<br /><br />c) $Fe(OH)_{3}\rightarrow Fe_{2}O_{3}+H_{2}O$<br />This equation is balanced.<br /><br />d) $NaOH+H_{3}PO_{4}\rightarrow Na_{3}PO_{4}+H_{2}O$<br />This equation is balanced.<br /><br />e) $ZnO+HCl\rightarrow ZnCl_{2}+H_{2}O$<br />This equation is balanced.<br /><br />So, the correct balanced equations are:<br />a) $3NO_{2}+H_{2}O\rightarrow 2HNO3+NO$<br />b) $Al_{2}O_{3}+SO_{3}\rightarrow Al_{2}(SO_{4})_{3}$<br />c) $Fe(OH)_{3}\rightarrow Fe_{2}O_{3}+H_{2}O$<br />d) $NaOH+H_{3}PO_{4}\rightarrow Na_{3}PO_{4}+H_{2}O$<br />e) $ZnO+HCl\rightarrow ZnCl_{2}+H_{2}O$
