What is true considering the bonding of atoms in clusters? O When atoms are bound in small clusters (i.e. nanoparticles) their behaviors are different because nanoscale behavior is different than macroscale O All of these answers are true. O Atoms typically do not bond to the same type of atom to make a molecule. OSmall gold nanoparticle clusters behave the same as larger ones. Atoms bound in small clusters (i.e. a few 100 atoms) behave the same as the bulk material (macro scale). O None of these answers apply.
Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
