Explanation :
Definition of potential energy : energy stored that depends upon the relative position of various parts of a system
Answer:
is the concentration of the compound in a solution.
Explanation:
Using Beer-Lambert's law :
Formula used :
Where:
A = absorbance of solution
C = concentration of solution
l = path length
= molar absorptivity coefficient
We have:
C = ? , l = 1.00 cm, A = 0.090
is the concentration of the compound in a solution.
A. The cell will not be able to maintain a stable internal environment.
By adding acid to a basic solution of pH 12, the overall solution
becomes less basic and the Ph of solution decreases to a value of 7, which is
known as the pH of a neutral solution, i.e neither basic nor acidic. This process
is called neutralizing the base.
Answer:
The formation of ice can also break rocks. If water gets into a crack in a rock and then freezes, it expands and pushes the crack further apart. When the ice melts later, water can get further into the crack. When the water freezes, it expands and makes the crack even bigger.
