Therefore insufficient iron in the water is the reason why he could find plenty phytoplankton in the ocean.
Adding an atom affect the position of existing atoms and lone pairs by changing the geomertry and <span>changing postion of the lone pairs and atoms so that they are furthest apart. Hope this answers the question. Have a nice day.</span>
The law of conservation of matter basically states that matter can’t be created or destroyed, only changed in form, so you can rule out any option that mentions destroying or creating matter. That leaves only option A. Atoms cannot be created or destroyed by chemical reactions.
