<span>From Beer-Lambert's law' A = ECl Since the slope is 1550.7 thus A = 1550.7* 0.000529 M = 0.8203203 Since A = Log (Io/I) and T% = I/Io * 100% Io/I = AntiLog(A) and hence T% = { 1/ AntiLog (A) } *100% T%={1/AntiLog 0.8203203)*100% T%=0.8601654108*100% T%= .860</span>

The degree to which various compounds will dissociate in solution varies greatly.

uranmaximum [27]

Answer: True

Explanation:

Weak electrolytes are those solutions which do not undergo complete dissociation when dissolved in water. The dissociation of weak electrolytes is given by an equilibrium.

Example: $CH_3COOH\rightleftharpoons CH_3COO^-+H^+$

Strong electrolytes are those solutions which undergo complete dissociation when dissolved in water. The dissociation of strong electrolytes is given by a right arrow.

Example: $HCl\rightarrow H^++Cl^-$

Thus the degree to which various compounds will dissociate in solution varies greatly is true.

Why does electronegativity increase as you move from left to right across

Katen [24]

Answer: increasing number of protons increases the positive charge of the nucleus.

Explanation: because as the electronegativity moves from left to right on the periodic table the protons do increase to make it into a positive charge.
