Which scenario suggest that the results of an experiment are reliable

What is a reliable scientific experiment?experiment, experimentation, experiments, reliable scientific experiment, science, scientific, scientific experiment, scientific experiments, scientific method

Now that the atheists have taken over science and have de-valued and discouraged experimentation I’ll try to re-value experimentation and encourage experimentation again like how it use to be prior to atheists taking over science in the late 1960s and early 1970s.

Why have atheists done this? It’s because experimentation gives us data that reflects reality, and often reality behaves very differently from how scientists want to think it does. Modern day atheist scientists want to find data that matches into their incredulity and mathematical models, not data that necessarily reflects how reality works.

Remember, experimental data is used to verify the accuracy of mathematical models, not the other way around like many modern day scientists think.

So I’ve come up with the basic properties of a highly reliable scientific experiment.

The Properties of a Reliable Scientific Experiment:

– Repeatability:  This means that the exact same results of the experiment are duplicated over and over again (when following the exact same set of systematic procedures). If the results of an experiment can be repeated over and over again yielding the exact same effect when following the exact same set of procedures, then the results of the experiment cannot be denied (although the results can possibly be interpreted differently). If your experiment only yields a certain result one time or a few times or in a non-repeatable condition then the experiment is not useful or scientific.

– Controls: Since correlation is not causation it’s important to have controls (if possible) to determine what’s causing certain results in an experiment. Having controls eliminates certain variables causing certain effects in the results of an experiment.

A simple example can be seen with determining which fertilizer is best for plant growth. In order to create a scientific experiment you would have to keep all the variables the same except for the fertlizer (these are the controls). Like the plant type, the amount of water each day, the time watered, the exposure to light, etc…

Without having control variables it would be unclear as to what’s causing the results in the experiment.

– <span>Not Relying on Subjective Users: </span> This ties into repeatability and means that the experiment doesn’t rely upon any subjective methodology, like only working if special users participate, a subjective bias or anything like that. Take for instance remote viewing experiments that only work if specially trained remote viewers participate. Since they would only work if special users participate it doesn’t give us any reliable repeatable data that’s useful in science.


So i hope this helps you and please makes this the brainly-est  answer...thanks

Draw a Lewis structure for H2O that obeys the octet rule if possible and answer the following questions based on your drawing. 1
Nataliya [291]

This is an incomplete question, here is a complete question.

Draw a Lewis structure for H₂O that obeys the octet rule if possible and answer the following questions based on your drawing.

For the central oxygen atom:

The number of lone pairs =

The number of single bonds =

The number of double bonds =

Answer : The Lewis structure for H₂O is shown below.

For the central oxygen atom:

The number of lone pairs = 4

The number of single bonds = 2

The number of double bonds = 0

Explanation :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

The representation of valence electrons of an atom by dots around the symbol of an element is said to be the Lewis-dot symbol.

In the representation of Lewis-symbol, one electron dot must put on each side of the element symbol then paired the electrons.

The given molecule is, H_2O

As we know that hydrogen has '1' valence electrons and oxygen has '6' valence electrons.

Therefore, the total number of valence electrons in H_2O = 2(1) + 6 = 8

According to Lewis-dot structure, there are 4 number of bonding electrons and 4 number of non-bonding electrons.

For the central oxygen atom:

The number of lone pairs = 4

The number of single bonds = 2

The number of double bonds = 0
