Let's balance the given chemical equations using any method:<br /><br />a) $H_{3}EO_{3}\rightarrow H_{2}O_{2}+H_{2}O$<br /> To balance this equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Let's start by balancing the oxygen atoms:<br /> $H_{3}EO_{3}\rightarrow H_{2}O_{2}+H_{2}O$<br /> Now, let's balance the hydrogen atoms:<br /> $H_{3}EO_{3}\rightarrow H_{2}O_{2}+H_{2}O$<br /> Finally, let's balance the phosphorus atoms:<br /> $H_{3}PO_{3}\rightarrow H_{2}O_{2}+H_{2}O$<br /> The balanced equation is: $H_{3}PO_{3}\rightarrow H_{2}O_{2}+H_{2}O$<br /><br />b) $F_{2}\downarrow +F_{2}+H_{2}O\rightarrow PH_{2}+H_{2}PO$<br /> This equation is not balanced correctly. Let's correct it:<br /> $F_{2}+H_{2}O\rightarrow 2HF+O_{2}$<br /> The balanced equation is: $F_{2}+H_{2}O\rightarrow 2HF+O_{2}$<br /><br />c) $HClO_{4}+r_{2}O\rightarrow H_{2}PO_{4}+ClO_{3}$<br /> This equation is not balanced correctly. Let's correct it:<br /> $HClO_{4}+H_{2}O\rightarrow H_{3}PO_{4}+ClO_{3}$<br /> The balanced equation is: $HClO_{4}+H_{2}O\rightarrow H_{3}PO_{4}+ClO_{3}$<br /><br />d) $H_{2}S+NO_{2}\rightarrow S+NO+H_{2}O$<br /> This equation is already balanced.<br /><br />e) $H_{3}SO_{4}+HBr\rightarrow SO_{3}+Br_{2}+H_{2}O$<br /> This equation is already balanced.<br /><br />f) $K+KCl+KCl\rightarrow K_{2}Cl_{2}+Cl_{2}+KCl+H_{2}O$<br /> This equation is not balanced correctly. Let's correct it:<br /> $2K+2KCl\rightarrow 2KCl+Cl_{2}+K_{2}O$<br /> The balanced equation is: $2K+2KCl\rightarrow 2KCl+Cl_{2}+K_{2}O$
