There are 100cm in a metre.
16.45=16+0.45.
Therefore 16.45m=1600cm+45cm=1645cm.

An atom is most stable when it has eight electrons in its outermost energy level.
Answer is: c. CuSO4 + 2NaOH yields Cu(OH)2 + Na2SO4.
Copper atom has oxidation number +2, sulfur atom oxidation number +6, oxygen has oxidation number-2, sodium has oxidation number +1 and hydrogen has +1 on both side of chemical reaction, so elements did not change their oxidation numbers.
