Naoh + h2so4→ na2so4 + h2o
a) balancea la ecuación (1)
b) ¿cuántos moles de na2so4 se forman a partir de 5 moles
de naoh?
c)cuantos gramas de h2o se forman a partir de 12,04 x
10^23 moléculas de h2so4?
d)si un mol ocupa un volumen de 22,4 litros ¿qué volumen
de na2so4 se forma a partir de 10 moles de h2so4?
e)¿cuántos gramos de naoh reaccionan con 16 g de h2so4?
f)cuantas moléculas de naoh se obtienen a partir de
44,8 litros de naoh?
no entiendo la ni la f si alguien me puede ayudar muchas gracias

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.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?
