1. How the size of cations and anions compares to the size of their neutral atoms and explain why
2. Define the term isoelectronic (same # electrons) and how the sizes of isoelectronic atoms compare
3. Define the Octet and Duet rule and how it explains the charges on common ions and both covalent and ionic bonding (for representative elements only)
A standard solution of sodium hydroxide has a molar concentration of 0.128M. You use 25.00ml of a solution of hydrochloric acid and this requires 32.75ml of the standardized sodium hydroxide solution to reach the endpoint. WHAT IS THE molar concen..
