Cierto gas ocupa un volumen de 5 l a 20 ºc y una presión de760 mmhg. si se comprime hasta 2500 cm3 a 1,2 atm, ¿cuánto valdrá su temperatura?

the link still does not work even when adding it to the url bar

explanation:

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
