Answer:
Fluorine
Explanation:
Fluorine has the greatest attraction for electrons in any bond that it forms. The attraction of an atom for shared electrons is called its electronegativity.
Answer:
yes because I seen one yesterday
Physical change
iron nail have high melting point, thus, when it is heated, it will not melt very easily.
chemical change
iron nail can rust due to the exposure to the air(oxygen). iron in the nail and oxygen in the air will react together to form iron oxide(rust).
furthermore, the reaction is irreversible.
Acetone is miscible because it has a C=O bond, while its C-C-C carbon chain makes it miscible with hexane. However, hexane is non-polar while water is polar, and since the two molecules have different polarities, they are immiscible.
