Do you think the air close to the ground behaves in the same way as the helium in the balloon when it is warmed up? Why or why not? plz explain the best way u can

In this case we use balloons filled with helium (or hydrogen). Helium is less dense than air even when the helium has the same temperature as the surrounding air. A helium-filled balloon doesn't need to warmed up in order to rise. ... As the balloon warms and expands its density of the helium decreases.

its weight is greatest on earth

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
