Consider this reaction: FeCl2 + 2NaOH -> Fe(OH)2(s) + 2Nacl If 6 moles of FeCl2 are added to 6 moles of NaOH, how many moles of NaOH will be used up in the reaction? (A. P.E. X)

A. 1
B. 6
C. 3
D. 2

The answer is 6.

Chemical energy is a form of a. kinetic energy only. b. both potential and kinetic energy. c. neither potential nor kinetic energy. d. potential energy only. reset

A50.0g sample of liquid water at 0.0 c ends up as ice at -20.0 c. how much energy is involved in this change?

Energy defines the different "states" of matter. in no more than 3 sentences, describe the amount of kinetic energy that each of the 3 states of matter possesses and relate that to the atom/molecular motion of each "state".
