Write the equations that represent the first and second ionization steps for hydroselenic acid (h2se) in water. (use h3o+ instead of h+.) first ionization step:

The equations are

1)

2)

Explanation:

There are two ionization steps in the dissociation of hydroselenic acid.

In first dissociation the H₂Se loses one proton and forms hydrogen selenide ion as shown below:

The next step is again removal of a proton from the base formed above.

i think it is d. e because the next one is igneous.
