A voltaic cell spontaneously converts chemical energy to electrical energy. The correct option among all the options given in the question is option "2".
Actually voltaic cell is an electrochemical cell that
converts the chemical contained within it by the process of chemical reaction
to produce electrical energy. The voltaic cell contains an anode and a cathode.
Anode is an electrode where the oxidation occurs and cathode is the electrode
where reduction occurs. The oxidation and the reduction part occurs in two
separate parts of the cell known as half-cell.
What details? I need more information than that
Answer:
382.5J
Explanation:
<em>Use the formula:</em>
E = mcΔθ or Q = mcΔT
m = 100g
c = 0.45 J/g°C
ΔT or Δθ = 110 - 25 = 85°
<em>Sub in the values:</em>
E = 100 × 0.45 × 85
= 382.5J
I think that different liquids have different freezing points because every liquid consists of different atoms and different things that make up the atom causing them to have different freezing points.
