I think the correct answer from the choices listed above is the third option. <span>In the redox reaction given, the element that was reduced was Fe or iron. It's charge reduced from +3 to zero, a neutral charge. Hope this answers the question. Have a nice day.</span>
I believe the correct answer from the choices listed above is option B. The stair-step line between the pink squares and the yellow squares separates the metals <span>from the nonmetals. Hope this answers the question. Have a nice day.</span>
Because molecular bonds are not as strong as ionic bonds, they require less energy (heat) to break apart. This translate to less heat being required to move from one state to the next (melting, boiling, freezing, condensing) and thus a lower melting and boiling point.
