Answer:
2cm^3
Explanation:
Use the density triangle: D=MxV
Switch for variables, V=M/D
Plug in numbers, 15.8g/7.9g/cm^3=2cm^3
Explanation:
Aquifers are porous and permeable formations that stores ground water. The ground water system is made up of mostly fresh water.
- An aquifer acts as a reserve for ground water in the environment.
- By passing through different formations, water that recharges them are purified.
- This makes them fresh and mostly free from salt intrusion
An aquifer is able to store this fresh water and it is is good prospect for sourcing ground water.
Newton's third law of motion states that for every action force, there is an equal and opposite reaction force so that means that the wall is pushing you with the same amount of force that you put on it.
You need to look at the electronegativity and decide wheter the difference of both of the numbers are significant enough to form a polar bond
