Answer:
The correct answer is - 7 cc or ml.
Explanation:
Given:
The volume of water in a graduated cylinder = 30 mL
The volume of rock = ?
Final volume = 37 ml
Formula:
If an object is placed in water, then the amount of water that is displaced or increased by submerging the object is equal to the volume of the object.
Vi + Vo = Vf
Vi = initial volume
Vo = volume of object
Vf = final volume
Solution:
Placing the values in formula -
30 + Vo = 37
Vo = 37 - 30
Vo = 7 ml or cc.

Oxygen is an element in the sixth group of the periodic table. This means it contains 6 electrons in its valence shell. Therefore, to complete its octet, it will prefer to gain two electrons rather than to donate 6. This is why its valency is -2. The relatively easy to achieve octet makes Oxygen a reactive element.
