6.6g of Carbon is completely oxidized to carbon dioxide then what amount of carbon dioxide is liberated at NTP ?

oh it is true if thats what you are asking

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
