A solution is made that is 1.2×10−3 M in Zn(NO3)2 and 0.130 M in NH3. After the solution reaches equilibrium, what concentration of Zn2+(aq) remains?

Explanation:

Equation for the reaction can be expressed as:

    ⇄    

From the equation above; we use the ICE table to determine how much complex ion forms  in order to be able to calculate  the at equilibrium.

So;

                                     ⇄    

Initial                                                    

Change                          

Equilibrium                                                    

  ⇒  

=  

=  

=

Therefore, the concentration of Zn2+(aq) after the solution reaches equilibrium =

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

the answer is true. hope it .
