Here we have to identify a piece of iron by its chemical property.
There are several chemical properties of iron for its identification but the simplest way to identify one of the renowned chemical property of iron is the formation of rust on iron in presence of water.
The iron in presence of water forms different types of iron oxides like hydrated Iron (III) oxide [Fe₂O₃.nH₂O], Iron (III) oxide-hydroxide [FeO(OH). Fe(OH)₃].
The rust is brown in color and forms only by keeping the iron piece in atmosphere. Although the humidity has an effect on the formation. The more humid the atmosphere there will be more chance to form rust on iron rod.
As Bond energy is between carbon and oxygen the is 358 for a single bond of C-0 and 745 for a double bond is the c=0.
- In the first step the one atom pulls the electron from another atom
. In the second step that is forming bonds releases energy and is the exothermic
. In the third step they pull electrons away from other elements
.
- In the last step the additional bonds is needed more energy to make or break, so the bond energy is very higher Hence the -153.
Learn more about the energy between carbon and oxygen is 358.

Answer:
A)distance = 0 and displacement = 0
B)distance = 10 meters and displacement = 0
D)distance = 10 meters and displacement = 10 meters
F)distance = 10 meters and displacement = 1 meter
In fact, displacement cannot be larger than distance, because distance is the total distance travelled in any direction, while displacement takes into account the direction. When the object moves only in one direction, distance and displacement are equal; however, if the motion of the object consists of several motions into more directions (like going back and forth), the distance travelled is always larger than the displacement. For this reason, choices C) and E) are wrong.
