The answer is the plague, or the black death
The elements should be label as follows yellow = OH, blue = Fe, green = Ba, red = Cl
The mix between aqueous barium hydroxide and aqueous iron chloride leads to barium chloride and iron hydroxide. This reaction is shown below:
- Ba(OH)2 + FeCl3 → BaCl2 + Fe(OH)3
Moreover, in these products, the iron hydroxide will form a solid substance that precipitates in the bottom of the container, while the barium chloride is more likely to maintain its liquid state.
According to this, the substance in the bottom is the iron hydroxide or Fe (OH)2, and in this, the yellow dots represent the Hydroxide or OH, while the blue dots are the Iron considering there in iron hydroxide there are two molecules of OH for each molecule of iron.
On the other hand, at the top, there is the barium chloride or BaCl2. This means the green dots are the Barium and the red ones are the Chlorine as there should be more Chlorine particles than Barium ones

Can u write it more specifically? so that I can answer
The array will be created with the elements equal to null.
D is the answer. A, B,C are absurd. Doing a little word right there.
