What is the concentration of CN^(-) ions in a solution with 0.1 M HCl and 0.01 M HCN where K_a of HCN is 10 ^(-6) ?

What is the [CN^(-)] in a solution prepared by mixing 100ml 0.1IM KCN and 100ml 0.2M HCI? (K_(x) " of " HCN = 5 xx 10^(-6) )

If a 0.1 M solution of HCN is 0.01 % ionised , the K_(a) for HCN is :

Explain the terms molecularity and order of a reaction. Give one example from each of first and second order reactions. A 0.1 M HCN solution contained 0.2 moles of KCN per litre of the solution. What was the hydronium ion concentration of the solution. (K_(a) for HCN = 7.2 xx 10^(-10) )
