Ba ( OH ) 2 Ba(OH)2 is a strong electrolyte. Determine the concentration of each of the individual ions in a 0.400 M Ba ( OH ) 2 0.400 M Ba(OH)2 solution.

[Ba^2+]= 0.400M

[OH-]= 0.800M

Explanation:

Step 1: Data given

Molarity ofBa(OH)2 = 0.400 M

Ba(OH)2 is a strong electrolyte, so 100 % dissociation

Step 2: The equation

Ba(OH)2 → Ba^2+ +  2OH-

In 1 mol Ba(OH)2 we have 1 mol Ba^2+ and 2 moles OH-

Step 3: Calculate the concentration

[Ba^2+]= 1* 0.400 M = 0.400M

[OH-]= 2*0.400 M = 0.800M

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
