Achemical reaction that has a positive δg is best described as

Explanation:

G is the symbol used for the Gibss energy, also known as free energy.

G measures the useful energy, i.e. the energy that can be used to perform a work.

G = H - TS and the change in G is given by δG = δH - TδS.

The sign of δG tells if a chemical reaction is spontaneous or not.

If δG is positive the reaction is non-spontaneous, if δG is negative the reaction is spontaneous, and if δG = 0 the reaction is at equilibrium. This can be written as:

Then, as to the given statement, it is completed with the term non-spontaneous, which corresponds to the description of a chemical reaction that has a positive δG.

i dont know

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.
