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.

Determine the pH of a 2.8 ×10−4 M solution<br> of Ca(OH)2.
shepuryov [24]

Answer:

pH = 10.75

Explanation:

To solve this problem, we must find the molarity of [OH⁻]. With the molarity we can find the pOH = -log[OH⁻]

Using the equation:

pH = 14 - pOH

We can find the pH of the solution.

The molarity of Ca(OH)₂ is 2.8x10⁻⁴M, as there are 2 moles of OH⁻ in 1 mole of Ca(OH)₂, the molarity of [OH⁻] is 2*2.8x10⁻⁴M = 5.6x10⁻⁴M

pOH is

pOH = -log 5.6x10⁻⁴M

pOH = 3.25

pH = 14-pOH

<h3>pH = 10.75</h3>

icang [17]

Answer:

Chlorine

Explanation:

Each arrow represents one electron. Most of the boxes are filled, meaning they have two electrons. The last box only has one arrow, so it only has one electron. If you add it up, you get 17, which is Chlorine.
