Which is characteristic of reliable experimental results?
storchak [24]

Answer:

B. The data were reproduced by other scientists using the same experimental methods.  

Explanation:

One of the features of reliable experimental results is their reproducibility — other scientists must be able to produce them.  

A. is wrong. An experiment that is designed to prove a hypothesis is biased.

C. is wrong. A conclusion based on a single experiment is suggestive but not conclusive. It takes a number of experiments to provide a strong statistical relation between the variables.

D. is wrong.  The data may support a conclusion that the they reached using logic and critical thinking, but there may still be a flaw in the thinking, which other scientists can point out.

Explain the concept of electron density
Doss [256]
Electron density is the measure of theprobability of an electron being present at a specific location.

In molecules, regions of electron density are usually found around the atom, and its bonds. In de-localized orconjugated systems, such as phenol,benzene and compounds such as hemoglobin and chlorophyll, the electron density covers an entire region, i.e., in benzene they are found above and below the planar ring. This is sometimes shown diagrammatically as a series of alternating single and double bonds. In the case of phenol and benzene, a circle inside a hexagon shows the de-localized nature of the compound.
