Why is it necessary to be able to replicate the results of a scientific experiment

Chemistry
1 answer:

Because it looses it's science-street-cred if it can't be replicated.

Essentially.

If you can replicate an experiment you can prove that the results are not just a stroke of luck or happening by chance, but instead that the variables are causing the results and they will always as long as the factors of the experiment remain the same. That is the definition of a <em>scientific</em> experiment.

How would an apple, potato, and onion all taste the same?
Firlakuza [10]

Answer:

If you were to plug your nose, it would block out more than 80% of taste, causing all three items to have no taste- therefore making them taste the same.

Methylpropane (complete and condensed structural formulas)
Tcecarenko [31]

Answer:

Here's what I get  

Explanation:

1. Complete structural formula

Methylpropane consists of a chain of three carbons with another carbon atom attached to the middle carbon. Enough H atoms are added to give each C atom a total of four bonds.

The complete structural formula is shown below (There is a C atom at each intersection).

2. Condensed structural formula

A condensed structural formula is designed to be typed on one line.

The molecule has three CH₃ groups attached to a single carbon atom, so the condensed structural formula is  

(CH₃)₃CH

The formula is also often written CH₃CH(CH₃)CH₃ and as (CH₃)₂CHCH₃.

Explain why the total amount of energy does not decrease in an exergonic <br> chemical reaction
Zielflug [23.3K]

An exergonic reaction is a chemical reaction where the change in the free energy is negative (there is a net release of free energy),[1] indicating a spontaneous reaction. For processes that take place under constant pressure and temperature conditions, the Gibbs free energy is used whereas the Helmholtz energy is used for processes that take place under constant volume and temperature conditions.

Symbolically, the release of free energy, G, in an exergonic reaction (at constant pressure and temperature) is denoted as

{\displaystyle \Delta G=G_{\rm {products}}-G_{\rm {reactants}}<0.\,}

Although exergonic reactions are said to occur spontaneously, this does not imply that the reaction will take place at an observable rate. For instance, the disproportionation of hydrogen peroxide is very slow in the absence of a suitable catalyst. It has been suggested that eager would be a more intuitive term in this context.[2]

More generally, the terms exergonic and endergonic relate to the free energy change in any process, not just chemical reactions. An example of an exergonic reaction is cellular respiration. This relates to the degrees of freedom as a consequence of entropy, the temperature, and the difference in heat released or absorbed.

By contrast, the terms exothermic and endothermic relate to the overall exchange of heat during a process
