which statement is true of the following reaction?\nh₂ + o₂→h⁺ + o²⁻\nit is balanced for oxidation state and for number of atoms.\nit is not balanced for oxidation state or for number of atoms.\nit is not balanced for oxidation state but is balanced for number of atoms.\nit is balanced for oxidation state but is not balanced for number of atoms.
Answer
Explanation:
Step1: Check atom - balance
On the left - hand side, we have 2 hydrogen atoms and 2 oxygen atoms in $H_2$ and $O_2$. On the right - hand side, we have 1 hydrogen atom and 1 oxygen atom in $H^+$ and $O^{2 -}$. So, the number of atoms is not balanced.
Step2: Check oxidation - state balance
In $H_2$, the oxidation state of hydrogen is 0; in $O_2$, the oxidation state of oxygen is 0. In $H^+$, the oxidation state of hydrogen is + 1; in $O^{2 -}$, the oxidation state of oxygen is - 2. The sum of oxidation states on the left is 0, and on the right is $+1+( - 2)=-1$. So, the oxidation state is not balanced.
Answer:
It is not balanced for oxidation state or for number of atoms.
