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 .
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
The true statement for this reaction is that urea (CO(NH2)2) reacts with water to form CONH2NH+3 and a hydroxide ion.
To determine which statement is true for the reaction between urea (CO(NH2)2) and water, we need to consider the reaction stoichiometry and the resulting products.
The balanced chemical equation for the reaction between urea and water can be written as follows:
CO(NH2)2 + H2O → CONH2NH3+ + OH-
Statement options:
1. The number of moles of urea is equal to the number of moles of CONH2NH3+ and OH- produced in the reaction: This statement is FALSE. From the balanced equation, we can see that one mole of urea reacts with one mole of water to produce one mole of CONH2NH3+ and one mole of OH-. Therefore, the number of moles of urea is not equal to the number of moles of the products.
2. The hydroxide ion is a product of the reaction: This statement is TRUE. From the balanced equation, it is evident that OH- is produced as a product of the reaction between urea and water. Therefore, the hydroxide ion (OH-) is indeed formed during this reaction.
Therefore, the correct statement is:
"The hydroxide ion is a product of the reaction."
To determine which statement is true, we analyzed the balanced chemical equation for the reaction between urea and water, and then compared it to the options provided.
