The Problem bother on the diffusion of substance
What is diffusion?
This can be defined as the movement of particles from a region of higher concentration to a region of lower concentration till equilibrium is reached
Explanation:
From the experiment seeks to measure the diffusion distance against time
Now when dye is dropped in water, the particles/molecules of the dye interacts with the molecules of water hence there is a mixtures which cause the dye to move from the initial position of higher concentration to lower concentration.
Hence the movement from the 0 mm mark increases in both directions

Answer:
Explanation:
Hello.
In this case, since the acid is monoprotic and the KOH has one hydroxyl ion only, we can see that at the equivalence point the moles of both of them are the same:
Thus, since we are given 1.70 g of the acid, we compute the moles of acid that were titrated:
Which equal the moles of KOH. In such a way, since the molarity is defined as moles over liters (M=n/V), the liters are moles over molarity (V=n/M), thus, the resulting volume is:
Best regards!
Answer:
Explanation:
The main task here is that there are some missing gaps in the above question that needs to be filled with the appropriate answers. So, we are just going to do rewrite the answer below as we indicate the missing gaps by underlining them and making them in bold format.
SO; In the quantum-mechanical model of the hydrogen atom.
As the n level increases. the energy <u>increases</u> and thus levels are <u>closer to </u>each other. Therefore, the transition <u>3p→2s</u> would have a greater energy difference than the transition from <u>4p→3p.</u>
