Recall the postulates of kinetic-molecular theory. read the list and check all the statements that apply to the behavior of an ideal gas: 1. gas particles behave like hard spheres 2. gas particles travel randomly 3. gas particles are attracted to each other 4. energy is lost when gas particles collide 5. average kinetic energy of a collection of gas particles depends on the temperature 6. gas particles occupy most of the space within a container 7. gas particles have mass and volume

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

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.
