Electrical energy turns into thermal, sound, radiant, and mechanical energy (all kinetic)
The permanent magnet in the loudspeaker is fixed close to a mobile electromagnet coil. The electromagnet is attached to a flexible material called cone (). Passing an electric current in the electromagnet causes it to vibrate due to the interaction with the permanent magnet.Uh hope this helped.
The first one is A because Sodium is a metal and Fluorine is a non metal so they will form an ionic bond. The second one is B because ionic bonds can only conduct electricity when dissolved in water or another aqueous solution. Hope this helps!
Molarity = Moles of solute / Liters of solution,
Convert 200 ml into Liters which is .2 Liters........ Then Do : (.155 / .2)
ΔG= ΔH - TΔS
YOU need to change the values to the same unit.. 42.08 J to Kj which is 42.08 x 10-3.
ΔG= (41.17) - (298K)(42.08x10-3)= 28.6 Kj/mol
because delta G is positive, it means this reaction is reactant favored.
