It is an exothermic reaction because the heat is released.
THE COMPLETE QUESTION IS:
Determine whether each cation is acidic or pH-neutral. For those cations that are acidic, write an equation that shows how the cation acts as an acid . a. NH+4 b. Na+ c. Co3+ d. CH2NH+3
Answer:
<em>a. Acidic</em>
<em>b. neutral</em>
<em>c. Acidic</em>
<em>d. Acidic</em>
Explanation:
a. NH4+ + H2O <==> NH3 + H3O+ (NH4+ is a conjugate acid of a weak base. Therefore it is acidic)
b. Neutral. Na+ is a cation of a strong base. Therefore it's pH is neutral.
c. Co(H2O)6³+ + H2O <==>CoH2O5(OH)²+ + H3O+
(Therefore Co+ is a weak acid since hydronium ion is formed.)
d. CH2NH3+ is a conjugate acid of a weak base. Therefore it is acidic.
Answer:
The answer is 79.904.
