(14.3)Identify the situation that will result in an exothermic enthalpy of solution. Group of answer choices When the magnitude of sum of heat of solute and heat of solvent is smaller than the magnitude of heat of mix. When heat of solute is equal to heat of hydration. When the magnitude of sum of heat of solute and heat of solvent is greater than the magnitude of heat of mix. When magnitude of sum of heat of solute and heat of solvent is equal to magnitude of heat of mix.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.

the correct answer would be d. hope this !
