When radon decays, it becomes polonium and yields a first-order rate law. If the rate constant is 0.175 days^-1 and you begin with a 8.64 g sample of radon:
(a) How much will be left after 2.96 days?
(b) How much will be left after 46.4 hours?
(c) What is the half-life of radon?
(d) How many grams of radon will be left after 5 half-lives?

hi,

the answer is d, it has indefinite shape but definite volume.

hope this !

*tilts head* sounds more like a statement

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.
