Write a balanced equilibrium equation for the dissolution of nai in water. include phases.
Bess [88]
Dissolution means to make the compound apart, So when we have ionic compounds like NaI which has metal and non-metal ions, It separates into parts of positive ions and negative ions. After we separate this compound apart we will put the charge of each on above its symbol and then start to balance the equation of the dissolution.

So the dissolution equation of NaI is:
NaI(s) → Na^+(s)  +   I^-(Aqu)

24. When the equation
serg [7]

Answer:

Explanation:

3

Explanation:

The reaction expression is given as:

     Al(OH)₃  +   HNO₃   →    H₂O   +  Al(NO₃)₃  

To solve this problem, let us assign coefficient a,b,c and d to each specie;

          aAl(OH)₃  +   bHNO₃   →    cH₂O   +  dAl(NO₃)₃  

Conserving Al : a  = d

                  O:  3a + 3b  = c + 9d

                  H: 3a + b  = 2c

                  N: b  = 3d

let a = 1 , d  = 1, b  = 3 , c = 3

 Multiply through by 3;

a  = 1, b  = 3, c = 3 and d  = 1

  Al(OH)₃  +   3HNO₃   →    3H₂O   +  Al(NO₃)₃
