Why is it important for scientists to review and repeat the work of other scientists?

Scientists repeat experiments for reliability.  Experiments have to be repeated, since performing an experiment only once, does not prove a scientists theory on the experiment, which they develop by performing the experiment.  And then performing the experiment again or even many times to prove or disapprove their theories.  Btw, before an experiment begins, the scientist will make a hypothesis of what they believe will happen.  If proven correctly, they would then use those results they record throughout the experiment, from beginning to end to prove whether or not their hypothesis are correct or incorrect.  Click to let others know, how helpful is it

So that they can prove the other scientists views wrong and develop a new theory in which there is more sense and credibility.

<h3><u>Answer;</u></h3>

2.The scientific method only applies to repeated experiments.

<h3><u>Explanation</u>;</h3>
  • <em><u>For a scientific method or scientific experiment to be viable it should be repeatable and falsifiable. This means the scientific experiment should be such that it can be performed by other scientists and similar results are obtained.</u></em>
  • <em><u>It is therefore important for scientists to repeat the investigations of other scientists so as to see if the results are similar and also can ask questions about an experiment and be in a position to point out problems if the exist.</u></em>
  • <em><u>However, some variations in results are acceptable, but the results from different scientists should be similar and consistent, and if not then the experiment must be done again.</u></em>

<h3>Further explanation </h3>

Given

Atomic symbol

Required

Atomic composition

Solution

Atomic number = number of protons = number of electrons

Mass Number (A) is the sum of protons and neutrons

Number of protons and Number of Neutrons  in nucleus

Number of electrons in the shell

From the picture:

protons = 3

neutrons = 4

electrons = 3

atomic number = protons = electrons = 3

mass number = protons + neutrons = 3+4 = 7

Potassium iodide (ki) exhibits predominantly ionic bonding. the k and i ions have electron structures that are identical to whic
Ad libitum [116K]
Inert gases are also called noble gases. They are the elements found in Group 8A in the periodic table. They are inert because they don't react with other elements. This is because they have the most stable electronic configuration. That's why elements form ions to gain or give way electrons so that they conform with the electronic configuration of the nearest inert gas. Basing on the periodic table, the nearest inert gas to K is Argon. The nearest inert gas to I is Xenon.

Use the graph below to answer the following question. Observe the ionization energy needed to remove the 10th and 11th electrons
natta225 [31]

The ionization energy will increase substantially when 11th electron is removed compared to when the 10th electron is removed.

<h3>What is ionization energy?</h3>

Ionization energy is the energy required to remove one or more electrons from a neutral atom in its gaseous state to form a positively-charged ion.

The ionization energy increases steadily as successive electrons are removed from an atom. A substantial increase in ionization energy occurs with the removal of an electron from a filled inner shell.

The 10th electrons is the last electron in the L shell of atoms. The 11th electron is the first electron in a  filled inner shell.

Therefore, ionization energy will increase substantially when 11th electron is removed compared to when the 10th electron is removed.

Note that there was no attached graph and the answer was given based on the general trend observed in ionization energies.

Which acid or base (along with its corresponding salt) should be used to generate a buffer solution with ph around 3. 5?
Sergio [31]

Formic acid, Sodium formiate will generate a buffer solution with pH around 3. 5.

It must consider the acid whose pKa = pH in order to choose the base or acid that can produce a buffer solution with such a pH of about 3.5.

However, it also need to consider buffer capacity, which is a factor that can alter the pH of a solution by one unit in a liter.

The connection between the components' concentrations and their concentrations themselves affects buffer capacity in addition to their individual concentrations.

Therefore, Formic acid, Sodium formiate will generate a buffer solution with pH around 3. 5.
