use the properties of sodium cyanide described above to deduce the type of bonding that holds this compound together, explaining in 1 or 2 short sentences how you arrived at your conclusions.

Write a balanced chemical equation for the reaction that occurs when sodium cyanide dissolves in water

You wrote no properties for the first part of your question. I shall be happy to critique your work.
For NaCN and H2O, the molecular equation is
NaCN + H2O ==> NaOH + HCN

The ionic equation is
CN^- + H2O ==> OH^- + HCN


Thank you
