The exposure of a person to colloids majorly present in industrial area may results in the accumulation in the body tissue which causes dark deposit in the skin. They are not safe and is dangerous for health which may cause turning of skin blue permanently and it is life long.
Whereas, the colloid of silver nitrate is used to treat skin burns and ulcers but its overuse may result in adverse effect.
The noble gases, because they already have a full valence shell

Answer:
A) the temperature of the water will increase.
Explanation:
Consider, first, the dissolution of anhydrous calcium chloride, CaCl2 in water. CaCl2 is a very water soluble ionic compound that, in solution, dissociates into the component ions, Ca2 + and Cl-, which interact strongly with water molecules.
The thermochemical equation that represents the process of dissolution of CaCl2 (s) indicates that it is a strongly exothermic process:
CaCl2(s) --> Ca+2(aq) + 2Cl- (aq) ΔH = -82.8 kJ
Therefore, dissolving CaCl2 in water will produce the release of energy in the form of heat (82.8 kJ per mole of dissolved CaCl2)
