B. All atoms of silver have the same atomic number but different numbers of neutrons in the nucleus.
Answer:
Use a commercially produced charcoalfilter
Explanation:
Water found in streams, depressions and ground water must be contaminated with pathogenic microorganisms. The methods of disinfection using iodine or bleach or boiling the water for about two minutes and then filtering it with a clean cloth will effectively remove the microorganisms.
However, charcoal filters do not eliminate microorganisms from water hence this method is not acceptable in this case.

C left over heat from the explosion was found
Answer:low lattice energy for the solid and a high hydration energy for its ions
Explanation:
The lattice energy is the energy that holds the ions in the crystal lattice together. This energy must also be supplied for the lattice to disintegrate into its component ions. When this energy is lower than the energy released during the hydration of ions, the lattice easily breaks apart releasing the ions which are now strongly hydrated and the ionic solid is said to be soluble in water. Hence, solubility is favoured by lower lattice energy and higher hydration energy.
