The average mass of all fluorine (F) atoms is 18.998 u.Do you think most fluorine atoms have 9 neutrons or 10 neutrons? Explain.
hodyreva [135]

Answer:

10 neutrons

Explanation:

The mass of is made up of the total protons and neutrons in an atom.

Each particle has a mass of 1 amu (atomic mass unit).

All fluorine atoms have 9 protons.

If each proton is 1 amu, the protons must contribute 9 amu to the total mass of the atom (9 x 1 amu = 9 amu).

This means the neutrons must contribute a total mass of 10 amu (18.998 amu - 9 amu = ~10 amu).

If each neutron has a mass of 1 amu, there must be 10 neutrons in a fluorine atom (10 amu / 1 amu = 10 amu).

xenn [34]

Answer:

See the complete question and the answer below

Explanation:

Sam and joe are trying to determine whether their ideas are scientific or pseudoscientific. sam's idea is not rejected when experiments produce different results. joe's idea gives the same result when tested repeatedly.  which statement is correct about sam and joe's idea?

<em>both ideas could be scientific. </em>

<em>neither idea could be scientific. </em>

<em>only sam's idea could be scientific. </em>

<em>only joe's idea could be scientific.</em>

<em />

The correct answer here would be that both ideas could scientific.

Scientific ideas are those that hold true or not rejected after being tested by different experiments. Pseudoscientific ideas cannot hold true after being tested by experiments.

If an idea is tested by repeated experiments and the experiments produce different results, the idea might remain unrejected if there are no overwhelming evidence to do so from the experiments. That an idea remains unrejected due to inadequate experimental evidence, however, does not mean it is scientific or unscientific.

In the same vein, that a repeatedly tested idea gives the same results does not mean that the idea is scientific unless the results say so. If results repeatedly go against the idea, it means such an idea is unscientific or pseudoscientific.

<em>Hence, both Joe and Sam's idea could be scientific, provided further experimental investigations are carried out.</em>

Models are used to show which qualities of a compound’s chemical structure? a. bond angles c. bond length b. element color d. bo
tino4ka555 [31]

Answer:

a. bond angles c. bond length

Explanation:

Models are abstractions of the real world. They are used to present either real or hypothetical situations either visually, graphically or through mathematical expressions.

  • In chemistry, to show bond angles and bond lengths, different models are used.
  • One of such is the VESPR - valence shell electron pair repulsion- theory which the model upon which the bond relationships between elements in a compound is shown.
  • Also, the hybridization schemes are excellent models for showing bond relationships.
