PLEASE HELP! ASAP In which reaction is there a transformation of mass into energy?
A. Uranium breaks apart into krypton, barium, and three neutrons.
B. Sodium combines with chlorine to form sodium chloride.
C. Hydrogen combines with oxygen to form water
D. Ammonium nitrate breaks down into dinitrogen monoxide and
water

Explanation:

Specifically, small amounts of mass are turned into energy from the breaking up (fission) or combination (fusion) of the nuclei of atoms. Even spontaneous radioactive decay converts a bit of mass into incredible amounts of energy.

A. Uranium breaks apart into krypton, barium, and three neutrons.

Explanation:

did the test !!

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
