1. True or false?
water is dipole
true
2. Describe how water has a partial positive and negative charge
oxygen (an electronegative atom) pulls the electrons from H, resulting in a partial positive charge
oxygens unpaired electrons result in a partial negative charge
3. the dipole characteristic of water allows ___ bonds to form
hydrogen
4. True or false?
Hydrogen bonding in water imparts its relatively low viscosity, surface tension, and boiling point
false; high
5. Hydrogen bonding between water and polar groups of bio-molecules allows water to be an excellent ___
solvent
6. Hydrogen bonding also occurs between various ___ groups of bio-molecules
polar
7. 1 dl = ___ ml
100
8. 50 g/L = ___ g/dl
5
9. Equivalent units are used for ions and are based on what?
available charges of the ion
10. For singly charged ions, one mole = ___ equivalent
one
11. For doubly charged ions, one mole = ___ equivalents
two ex: [Mg+2]
12. True or false?
pH can affect enzyme activity
true
13. Define osmolarity
the total number of solute particles in a solution
14. 1M NaCL solution is ___ Osmolar
2
15. True or false?
