Nitrogen is lighter than oxygen
carbon dioxide is heavier than oxygen therefore oxygen is lighter.
If "heavier than" in the question is interpreted to mean "has an atomic mass greater than", the answer is nitrogen
humid air is lighter that an equal volume of dry air at the same temperature.
a falling barometric reading often means rainy weather
No, it is heavier than air and will sink to the floor.
Nitrogen is lighter than oxygen
carbon dioxide is heavier than oxygen therefore oxygen is lighter.
nitrogen is lighter than oxygen

In fact there are seven elements lighter than oxygen: hydrogen, helium, lithium, beryllium, boron, carbon and nitrogen.
no. If it was, we would have oxygen balloons instead of helium balloons.
yes at ATM and temp
A compound is not lighter than an element, if that element is part of the compound. Some compounds, like H2O would be lighter than, say, the element lead, but it is not lighter than the elements that make it up, i.e. hydgrogen and/or oxygen.
Helium is lighter (less dense) than oxygen & nitrogen.
hydrogen gas which is lighter than oxygen
Helium is lighter than oxygen and can escape the ozone.
