it is important
because chemistry seeks to explain the submicroscopic events that lead to macroscopic observations
. – quantitative: tells quantity of a chemical formed or how much of a chemical is used.
Why is it necessary to use models to study submicroscopic?
Why is it necessary to use models to study submicroscopic objects such as atoms and molecules? A.
These objects do not exist in the real world.
… These objects can only be described mathematically.
Why is it important for chemists to study changes in the world at submicroscopic level?
The changes you see with your eyes begin with changes at the submicroscopic level. Models
enable chemists to understand difficult concepts that they cannot normally see
.
What objects are submicroscopic?
Submicroscopic refers to the domain that
includes small particles that make up all matter
, such as an atom (the smallest unit of matter that retains the properties of that element).
What are the 3 types of scientific models?
Physical models, mathematical models, and computer models
are common types of scientific models.
Which branch studies the environmental impact of chemicals?
Analytical chemistry studies the composition of substances;
environmental chemistry
studies the environmental impact of chemicals.
Why is it important for chemists to study changes?
The changes you see with your eyes begin with changes at the submicroscopic level. Models

.
What is chemistry in long?
Chemistry, the
science that deals with the properties, composition, and structure of substances
(defined as elements and compounds), the transformations they undergo, and the energy that is released or absorbed during these processes.
Why do chemists study matter?
Chemistry seeks
to understand not only the properties of matter
, like the mass or composition of a chemical element, but also how and why matter undergoes certain changes — whether something transformed because it combined with another substance, froze because it was left for two weeks in a freezer, or changed colors …

What is considered submicroscopic?
1 :
too small to be seen in an ordinary light microscope
. 2 : of, relating to, or dealing with the very minute the submicroscopic world.
What are 4 types of models?
The main types of scientific model are
visual, mathematical, and computer models
.
How accurate are scientific models?
Models have always been important in science and continue to be used to test hypotheses and predict information.
Often they are not accurate
because the scientists may not have all the data. It is important that scientists test their models and be willing to improve them as new data comes to light.
Can scientific models can never be changed?
Can scientific models can never be changed? Scientific models can never be changed. Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.
What is the study of the harmful effects of chemicals on humans and other organisms?
Toxicology
is a field of science that helps us understand the harmful effects that chemicals, substances, or situations, can have on people, animals, and the environment.
