Question

Which statement is true of the following reaction? H2 + O2 -> 2H + O2-

-It is balanced for charge and for number of atoms.
-It is not balanced for charge or for number of atoms.
-It is not balanced for charge but is balanced for number of atoms.
-It is balanced for charge but is not balanced for number of atoms.

Answer 1

The answer is B: It is not balanced for charge or for number of atoms.

Step-by-step explanation:

Answer 2

Correct Answer: Option B i.e. It is not balanced for charge or for number of atoms

Reason:
In the present reaction of interest is

`H_(2) + O_(2) ---\ \textgreater \ 2H + O^(-2)`

There are reactant side has 2 oxygen atoms, whereas product side has only one oxygen atom. Hence, mass is not balanced.

Also, overall charge on reactant side is zero, but on product side is -2. Hence, charge of reaction is not balanced.
