A certain hourglass contains 0.71500 mº of sand and the sand passes through the hourglass at a rate of 0.530 inper second. How many minutes will it take the sand to pass through the hourglass?​

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.
