Reaction Rate is the rate at which a substance undergoes a chemical change.
Answer:
A
Explanation:
Electron geometry describes the arrangement of electron groups. Molecular geometry describes the arrangement of atoms, excluding lone pairs.
Not 100% sure if its right.
When an object covers equal distances in equal amounts of time, it is moving at a constant speed.
Option (a) is correct.
A reducing agent is the one which loses electrons to other substance.
Here, Zn has oxidation number 0 in the L.H.S of the equation, but on R.H.S its oxidation number is +2 i.e. it Zn has donated two of its electrons to
.
Hence, Zn is the reducing agent here.
