In a chosen ciphertext attack, what capability does the adversary have?

How does OFB mode handle plaintext lengths that are not multiples of the block length n?

What is a Keyed-Hash Message Authentication Code (HMAC)?

Using the concept of electroneutrality and the cahrge on an O ion- indicate the charge of the mystery cation X in the following IONIC compound.  XO2

Draw the electron dot (Lewis) structures for N2, O2, and F2 in order to answer the following question(s).  (1) Describe the difference in bonding within these molecules (what do your correct Lewis structures look like?). Be sure to indicate how many bonds, what types of bonds and the location of any lone pairs of electrons.  (2) Discuss number of bonded and non bonded electrons AND the distribution of electron density (polarity!) around the molecule.

In these chapters we have learned about types of bonding, intermolecular forces, calculations throughout chemcical reactions, and gas phase chemsitry. List 2 places you think these topics may come up in your future carreers as a nurse.
