Question

Identify each of the underlined items as a part of either the macroscopic domain, the microscopic domain, or the symbolic domain of chemistry. For those in the symbolic domain, indicate whether they are symbols for a macroscopic or a microscopic feature.

(a) A certain molecule contains one H atom and one Cl atom.

(b) Copper wire has a density of about 8g/cm³.

(c) The bottle contains 15 grams of Ni powder.

(d) A sulfur molecule is composed of eight sulfur atoms.

Short answer

1. Microscopic domain and symbolic domain
2. Macroscopic domain
3. Macroscopic domain and symbolic domain
4. Microscopic domain

Step-by-step solution

The macroscopic domain:

It's the realm of ordinary objects large enough to be felt or seen instantly by humans. This includes consuming food and the feeling of the breeze on your face, etc.

The microscopic domain:

Almost always, the microscopic realm of chemistry is visited by the imagination. Micro is a Greek word that means "little." A microscope may reveal some elements of the microscopic realms, such as a magnified image of graphite or bacteria.Viruses, for example, are too small to be seen with the human eye, yet we're reminded of their existence when we get a cold.

The symbolic domain:

The symbolic domain houses the specific language used to represent macroscopic and microscopic domain components.Graphs, drawings, chemical symbols (such as those used in the periodic table), chemical formulas, and chemical equations are all part of the symbolic domain. Calculations can also be considered part of the symbolic domain.
