Answer 1

Answer:

mark brainliest

Explanation:

Carbon dioxide is denser than nitrogen and oxygen (i.e. air), so the balloon filled with carbon dioxide is heavier and sinks in the air faster than the balloon filled with normal air.

Answer 2

Answer:

Hydrogen filled balloons generally rises up in the air. This is because hydrogen is less dense and its weight is also less than the air. The one filled with carbon dioxide generally sinks down as it is denser than the air and due to its heavy weight, it cannot rise up to the ceiling.
