The answer to the question is letter 'C', water can be made to boil at 105 degrees Celsius by decreasing the air pressure on the water. Boiling occurs when the water is hot enough to have the same pressure as the surrounding air. at high altitudes the air pressure is lower than the sea level, it possible that the boiling of water can be raise until 105 degrees.
Isoelectronic species are ions or elements that have equal number of electrons. From the root word, electron of the word isoelectronic. On the other hand, isotructural species are compounds with the same structures.Hope this answers the question.
I only identify decomposition
<span>An explosion that releases great amounts of heat is an example of an exothermic process. Any reaction that gives off or releases energy as light, electricity, heat, or sound is considered to be exothermic, with "exo" meaning "outside". An explosion is one of the most extreme cases of exothermic reactions.</span>
