HELP FAST The diagram shows two bowling balls of equal mass. Ball A is resting near
the
edge of a shelf. Ball B is resting on the ground below.
Which of these statements best describes the diagram above?
a) Ball A has more kinetic energy than Ball B.
b) Ball B has more kinetic energy than Ball A.
c) Ball A has more potential energy than Ball B.
d) Ball B has more potential energy than Ball A.

C

Explanation:

none of the balls have any kinetic energy if there not moving, but Ball A have potential from gaining kentic energy from falling. Remember this if some thing is on a table it have potential to gain kentic energy from falling.

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.
