Refer to the following descriptions of bonding in different types of solids.(a) lattice of positive and negative ions held together by electrostatic forces(b) closely packed lattice with delocalized electrons throughout(c) strong covalent bonds with weak intermolecular forces(d) strong multiple covalent bonds (including π bonds) with weak intermolecular forces(e) macromolecules held together with strong polar bonds

It will fall off and tip over. 

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.
