Question

Urea (CO(NH2)2) can react with water to
form CONH2NH+
3 and a hydroxide ion.
Which statement is true for this reaction?

Answer 1

1. H2O is the conjugate base of
CONH2NH+
3 .
2. The hydroxide ion is the conjugate acid
of CONH2NH+
3 .
3. The hydroxide ion is the conjugate base
of CONH2NH+
3 .
4. CO(NH2)2 is the conjugate base of
CONH2NH+
3 .
5. CO(NH2)2 is the conjugate acid of
CONH2NH+
3 .
6. H2O is the conjugate acid of
CONH2NH+
3 .

Answer 2

I think you meant this for the equation.
I followed with the next two lines showing acid, base, conj acid, conj base. I think if you type the equatiion right you will see the answer. Also you need to restructure the answers to get them right.
CO(NH2)2 + HOH ==> CONH2NH3^+ + OH^-
base................conj acid
...........acid................conj base
