The addition of which aqueous ion to a solution of sodium hydroxide would result in the formation of a precipitate? A. O2− B. H+ C. S2− D. Fe3+

Fe3+

Explanation:

NaOH(aq)+ Fe3+ gives Fe(OH)3 which is insoluble in excess sodium hydroxide

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
