# Consider the following reaction equation: SO42-(aq) + 2H+(aq) + ye- → SO42-(...

### Question

Consider the following reaction equation:
SO42-(aq) + 2H+(aq) + ye- → SO42-(aq) + H2O(l).

The value of y in the equation is

A) 2

B) 3

C) 4

D) 6

### Explanation:

From the reaction, the total charge on the left side is equal to the total charge on the right side.
-2 + 2 + y = -2
y = -2
The value of y is 2.

## Dicussion (1)

• From the reaction, the total charge on the left side is equal to the total charge on the right side.
-2 + 2 + y = -2
y = -2
The value of y is 2.
