Two vessels containing gases are separated by a stopcock. The first holds 2.0 L of nitrogen at 1.0 atm and 25°C; the second contains 3.0 L of oxygen at 2.0 atm and 25°C. (a) When the stopcock is opened, how does the volume of N, change? What is the partial pressure of N, after mixing? (b) How does the volume of O, gas change after mixing? What is the partial pressure of O, in the mixture? (c) What is the total pressure of gas in the mixture?​

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.

answer; natural resources;

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
