The correct option is d

Explanation:

There are several ways of harmlessly disposing chemical wastes and as such some chemical wastes have special disposal methods (for example hazardous wastes such as inflammable wastes, corrosive wastes and poisonous wastes).

For the reasons above, it is necessary for the teacher's instruction to be followed in disposing the waste because the teacher will have a better knowledge of the class of waste and the best method to harmlessly dispose such waste (most especially because of the large waste produced) .

Mendeleev positioned elements in the periodic table in increasing order of their atomic numbers, such that elements having identical chemical properties and characteristics plunge into the same group.

What is Mendeleev's periodic table called?

In order to represent similarities and patterns in the behavior of elements, Mendeleev created the periodic table, which is an arrangement of elements in an increasing atomic mass order in tablet form.
Mendeleev stated that "Element characteristics are a periodic function of their atomic weight" in his renowned periodic law.
The Periodic Table of Mendeleev is a table that Mendeleev created to list elements in the order of their atomic weights.

Mendeleev discovered that there were two elements with atomic weights between 65.2 and 75 because he found it very satisfying that the properties of the elements were more similar and closer to this level.
He also imagined having other elements with possessions similar to those of these other elements.
In the periodic table, he left a blank for these two elements until they were finally discovered in their true existence.

Compare and contrast diffusion and osmosis. Include at least one similarity and one difference between the two processes.

Softa [21]

Osmosis is the diffusion of water across a semipermeable membrane (usually cell membrane) from a region of low solute concentration to a more concentrated solution so it can reach equilibrium (balance).

Diffusion is a spontaneous movement of particles from an area of high concentration to an area of low concentration.

Both results in particles moving and help balance out the concentrations.
Also, in osmosis, the water molecules are moving. In diffusion, it is the solutes moving.

I hope this helps and explains well.
