Green food coloring diffusing through cookie dough.

Explanation:

Entropy is a physical quantity for an equilibrium thermodynamic system that measures the degree of organization of the system, or that is the ratio of an increase in internal energy to an increase in temperature of the system.

When the green dye diffuses through the cookie dough there is an increase in entropy, that is, there is an increase in system disorder at the molecular level, where a change in cookie dough occurs.

B. green food coloring diffusing through cookie dough

Explanation:

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.
