Everyone in Mrs. Blaylock's science class must perform an experiment for the science fair this year. To begin this process, Mrs.

Blaylock asks her students to brainstorm four different questions that they could study.
One of Mrs. Blaylock's students writes down the following questions.
How does the mass of a toy car affect its speed down a ramp?

How does the position of the Sun, moons, planets and stars affect a person's personality traits and daily behavior patterns?

Which type of pan - copper, aluminum, or glass - heats up the quickest?

Which type of chemicals can remove the cell wall of a plant cell?
Which of the above questions cannot be answered through a scientific investigation?

How does the position of the Sun, moons, planets and stars affect a person's personality traits and daily behavior patterns

Explanation:

The question that cannot be answered scientifically from the given choices is "how does the position of the Sun, moons, planets and stars affect a person's personality traits and daily behavior patterns".

This problem is off the jurisdiction of natural science.

  • Scientific questions are usually empirical in nature and draws relationship between two variables.
  • Usually, one variable changes and the other is affected.
  • This problem stated is subjective and not scientific.
  • Humans have a wide range of personality traits.
  • This problem can be solved using a psychological analysis.

What is the mole fraction of NaCl in a mixture containing 7.21 moles NaCl, 9.37 moles KCL, and 3.42
GrogVix [38]

Answer : The mole fraction of NaCl in a mixture is, 0.360

Explanation : Given,

Moles of NaCl = 7.21 mole

Moles of KCl = 9.37 mole

Moles of LiCl = 3.42 mole

Now we have to calculate the mole fraction of NaCl.

\text{Mole fraction of }NaCl=\frac{\text{Moles of }NaCl}{\text{Moles of }NaCl+\text{Moles of }KCl+\text{Moles of }LiCl}

Now put all the given values in this formula, we get:

\text{Mole fraction of }NaCl=\frac{7.21}{7.21+9.37+3.42}=0.360

Therefore, the mole fraction of NaCl in a mixture is, 0.360

What neutral element has the electron configuration described by the Aufbau diagram above.​
devlian [24]

Answer:

Aluminium.

Explanation:

The above electronic configuration can be written in a simplified form as shown below:

1s² 2s²2p⁶ 3s²3p¹

Next, we shall determine the number of electrons in the atom of the element as follow:

Number electron = 2 + 2 + 6 + 2 + 1

Number of electron = 13

Next, we shall determine the number of protons.

Since the element is in its neutral state,

The number of electrons and protons are equal i.e

Proton = Electron

Number of electron = 13

Proton = Electron = 13

Proton = 13

Next, we shall determine the atomic number of the element.

The atomic number of an element is simply the number of protons in the atom of the element i.e

Atomic number = proton number

Proton = 13

Atomic number = 13

Comparing the atomic number of the element with those in the periodic table, the element with the above electronic configuration is aluminium since no two elements have the same atomic number.
