Document Summary

Clicker quiz: an electrically neutral atom with an atomic number of 8 and a mass number of 17 has: c. 8 protons. Clicker quiz: the energy stored in the chemical bonds between atoms in a large molecule is d. potential energy. Be able to predict if exergonic and endergonic. Clicker quiz: the digestion of food is exergonic since chemical bonds are broken and energy is released true. Clicker quiz: enzymes bind with substrates at their active sites and are permanently altered by the binding process. Hydration spheres: keep ions apart and hides their charge so they can float around.

All bases are electrolytes: will ionize and dissociate in water. Bases are proton acceptors: more hydrogen ions it accepts, the more basic it is, releases hydroxyl ions.
