Is chemistry even a science?
Even though chemistry is
more like an applied science
and often relies on models rather than on pure theories, one can envision fundamental theories that would fall under Popper’s narrow definition that can only or principally be falsified by organic chemists.
What are four goals of questions that chemistry tries to answer?
Think of the scientific method as having four goals (
description, prediction, explanation and control
). It is important to remember that these goals are the same for anything that can be studied via the scientific method (a chemical compound, a biological organism, or in the case of psychology, behavior).

Why do physicists hate chemists?
Physicists attempt
to study complexity and reduce it to simplicity
. Chemistry is more interested in how atoms behave with one another as they form molecules. So instead of reducing to the simplest principles, chemists want to know how elements interact with one another when they are combined into compounds.

If you are asked to identify the Father of Chemistry for a homework assignment, your best answer probably is
Antoine Lavoisier
. Lavoisier wrote the book Elements of Chemistry (1787).

Chemistry
! As our understanding of the universe has changed over time, so has the practice of science. Chemistry in its modern form, based on principles that we consider valid today, was developed in the 1600s and 1700s.
Is Dark Matter real?
Because
dark matter has not yet been observed directly
, if it exists, it must barely interact with ordinary baryonic matter and radiation, except through gravity. Most dark matter is thought to be non-baryonic in nature; it may be composed of some as-yet-undiscovered subatomic particles.

Many scientists believe that
RNA
, or something similar to RNA, was the first molecule on Earth to self-replicate and begin the process of evolution that led to more advanced forms of life, including human beings.

Why science Cannot provide answers to all questions?
Science Cannot Provide Complete Answers to All Questions
There are many matters that cannot usefully be examined in a scientific way
. There are, for instance, beliefs that—by their very nature—cannot be proved or disproved (such as the existence of supernatural powers and beings, or the true purposes of life).
What are the 5 limitations of science?
- Must deal with observable measurable phenomenon.
- Science can describe not explain.
- No experiment can be completely controlled.
- Observations may faulty.
- A mans belief effects his judgment.

- Science cannot deal with values or morals.
Is the universe infinite?
The observable universe is finite in that it hasn’t existed forever
. It extends 46 billion light years in every direction from us. (While our universe is 13.8 billion years old, the observable universe reaches further since the universe is expanding).
Why Should aspirin be stored in a cool dry place chemistry?
Insulin can also be altered by bacterial growth that breaks down the protein making the drug ineffective. … Moisture can decrease the effectiveness of drugs. An example is aspirin.
Aspirin breaks down even in low moisture environments
; therefore, care should be taken to store aspirin in dry, temperature-controlled areas.
Are atoms of given elements identical?
each element is made up
of identical particles of matter
called atoms. all the atoms in a pure substance or element are identical to one another but different to the atoms in a different element.
Are open-ended questions?
What are open-ended questions? Open-ended questions are
