Athief plans to steal a gold sphere with a radius of 28.5 cm from a museum. if the gold has a density of 19.3 g/cm3, what is the mass of the sphere in pounds? [the volume of a sphere is v=(4/3)πr3.]

Calculate the volume of the sphere by substituting the radius on the given equation. The volume would be 96966.83 cm3. Then multiply the volume with the given density which is 19.3 g/cm3. Convert the mass obtained by dividing it with 453.592 g (1 lb = 453.592 g). The answer would be 4125.87 lb. 

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

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.
