Not sure the precise concept of "normal observation", but I assume that is observed by "eyes".
Eye observation is basically macroscopic, but when you use a mark, which can be regarded as a point of mass, then it goes to microscopic.
Mark is a reference point which you can compare the relative position change, but with your eyes, first you cannot notice microscopic changes, second the eyes cannot precisely set a stable reference point.
Any form of succession will change the environment. That's why there is succession in the first place. With each stage of succession there will be greater biodiversity that results in a change in abiotic factors like soil composition, shade, humidity, weather, exposure, etc
Answer:
1.865 * 10^-4 L
Explanation:
The equation of the reaction is:
4OH^-(aq) ----->2H2O(l) + O2(g) + 4e
Since one mole of oxygen which occupies 22.4 L is produced in the electrolysis of water by 4 Faraday of electricity as shown in the equation above;
Then;
4 * 96500 C liberates 22.4 L of oxygen
60 * 60 * 0.0200 C will liberate 60 * 60 * 0.0200 * 22.4/4 * 96500
= 1.865 * 10^-4 L
And.. where is the rest of the question?
