Answer:

A reliable scientific study is supported by empirical evidence.

Explanation:

Science is the set of knowledge that is organized systematically obtained from observation, experimentation and reasoning within specific areas. In other words, science is empirical knowledge of the universe that is established according to the principles of the scientific method. The scientific method will vary according to the type of field of study, but you can define how the process by which a theory can be demonstrated or refuted. The scientific method is then defined as a set of ordered steps that are used to acquire new knowledge. In order to be qualified as a scientist, it must be based on empiricism, on measurement and, in addition, must be subject to reason. It is characterized by reproducibility, that is, the ability to repeat a given experiment, anywhere and by anyone. Another characteristic of the scientific method is refutability, that is, that every scientific proposition has to be susceptible to being falsified or refuted. This implies that experiments could be designed, which, in the case of giving different results to those predicted, would deny the hypothesis tested.

Then, as a reliable scientific study and science is based on the scientific method, which in turn is supported by experimental evidence, it is possible to say that a reliable scientific study is supported by empirical evidence.

13. Which statement best describes an element? *

Natasha2012 [34]

Explanation:

Distinguish chemical substances from mixtures

Key Points

Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components.

A chemical substance is composed of one type of atom or molecule.

A mixture is composed of different types of atoms or molecules that are not chemically bonded.

A heterogeneous mixture is a mixture of two or more chemical substances where the various components can be visually distinguished.

A homogeneous mixture is a type of mixture in which the composition is uniform and every part of the solution has the same properties.

Various separation techniques exist in order to separate matter, including include distillation, filtration, evaporation and chromatography. Matter can be in the same phase or in two different phases for this separation to take place.

Terms

substanceA form of matter that has constant chemical composition and characteristic properties. It is composed of one type of atom or molecule.

elementA chemical substance that is made up of a particular kind of atom and cannot be broken down or transformed by a chemical reaction.

mixtureSomething that consists of diverse, non-bonded elements or molecules.
