Explanation:

Physical change is a change that does not affect the chemical composition of a substance but it changes the physical appearance like size or shape of the substance.

For example, crushing a can, melting of ice, breaking a glass etc represents the physical change.

Scenarios which represent examples of physical changes are as follows.

  • Silicon is cut into tiny pieces for computer chips.
  • Lead is melted to form pellets.
  • Liquid water freezes to form ice.

Vikki [24]

Answer:

1.58×10E18

Explanation:

Since we have the reduction potentials we could make decisions regarding which one will be the anode or cathode. Evidently, bromine having the more positive reduction potential will be the cathode while the iodine will be the anode.

E°cell= 1.07- 0.53= 0.54 V

E°cell= 0.0592/n logK

0.54 = 0.0592/2 logK

logK= 0.54/0.0296

logK= 18.2

K= Antilog (18.2)

K= 1.58×10^18
