The correct answer is option 2. When Pt2+ is reduced it loses electrons, oxidizing it. The oxidation number is the charge of the atom. Adding an electron, decreases the net charge consequently the oxidation number.
Typical air flow i believe hope i helped
S waves
- The motion of the medium is perpendicular to direction of propagation of the wave
.
- They can propagate only through solids and not through gases or liquids
.
- They travel with less speed
.
P waves
- These are compression waves
.
- These waves produces a force along the direction of propagation
.
- They can propagate through solids, gases and liquids.
- P waves are smaller than s waves
.
- They travel with 60% greater speed than S waves
.
P-waves travel 60% faster than S-waves on average because the interior part of the Earth does not react the same way as the s wave and P wave.
