Answer:
I remember learning about this in health class. I believe the answer is quality of life.
Explanation:
To fill up all of the valence electrons we must have 8 electrons total to have an ionic bond. In this case Lithium is in group 1 and so only has 1 valence electron and so it can bond with elements from group 17, since 7 + 1 = 8. However, this unknown element did bond with beryllium, and beryllium is in group 2 so it must bond with an atom that has 6 valence electrons. The elements that have 6 valence electrons are in group 16 not group 2. So the result does not support her conclusion.
Answer:

Explanation:
Since we are given time, acceleration, and final velocity, we can use the following formula to find the initial velocity:

Our given values:

<em>Acceleration is negative because the car is slowing down.</em>
Add the values to the formula, and solve for
:
