Among the given options, the element that has the lowest ionization energy is beryllium. Thus, the correct option for this question is C.
What do you mean by Ionization energy?Ionization energy may be defined as the amount of energy that is significantly required in order to eliminate an electron from an isolated atom or molecule. It is the minimum energy required to remove the most loosely bound electron of an isolated gaseous atom, positive ion, or molecule.
The group of elements that have the lowest ionization energy is known as alkali metals or alkali earth metals. This is because of the shielding effect that the ionization energy decreases from top to bottom within a group. Beryllium is a member of group 2 which has the lowest ionization energy. While Fluorine is said to have the highest ionization energy.
Therefore, the element that has the lowest ionization energy is beryllium. Thus, the correct option for this question is C.

A student who was training for a cross-country race jogged for 1.0 hour and covered a distance of 1.5 kilometers. How much farther will the student travel if he jogs for one more hour?
Answer:
He would travel 3 kilometers.
Explanation:
Since he had already covered 1.5 kilometers in the time of 1 hour that means if he jogged for 1 more hour assuming he is going at the same pace he would've jogged 1.5 kilometers again and when you add that to the 1.5 kilometers he started with it would add up to 3 kilometers.

At which pesan pressure lowest The image shows a representation of mountains of various heights, numbered 1, 2, and 3 The plami tabeled number 4 OOOO
1 is the lowest pressure.........
The pressure inside of a sealed syringe of hydrogen gas is 80.0KPa with a volume of 250 Liters. What is the pressure inside
of the syringe after the plunger is pulled back far enough to make final volume of the syringe 0.750 Liters? (assume the
temperature and amount of gas in the container are held constant)
Answer:
26666.67 kPaExplanation:
The new pressure can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we are finding the new pressure
[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]
From the question we have
[tex]P_2 = \frac{80000 \times 250}{0.75} = \frac{20000000}{0.75} \\ = 26666666.6666 \\ = 26666667[/tex]
We have the final answer as
26666.67 kPaHope this helps you

During a lab you measure the height of your graduated cylinder as 5.75 inches. You later read that you were asked to record it in meters. Convert your measurement into meters in order to get full credit on your lab. Express your answer in scientific notation.
Answer:
1.4605 x [tex]10^{-1}[/tex] meter.
Explanation:
According to the standard method of conversion of units:
1 inch = 0.0254 meter
Therefore, 5.75 inches would be:
5.75 x 0.0254
= 0.14605 meter
0.14605 meter in scientific notation would be 1.4605 x [tex]10^{-1}[/tex] meter.
Hence, the 5.75 inches height would be 1.4605 x [tex]10^{-1}[/tex] meter.

Substance 2 has a stronger molecular attraction.
What are solids?Solid is one of the four fundamental states of matter. The molecules in a solid are closely packed together and contain the least amount of kinetic energy. A solid is characterized by structural rigidity and resistance to a force applied to the surface.
Both solids are supplied with an equal amount of energy. Out of both substances, substance 2 has a stronger molecular attraction due to which it can not easily change into a liquid while substance 1 has a lesser molecular attraction so supplying of few amounts of heat will change substance 1 into a liquid state.
Hence, Substance 2 has a stronger molecular attraction.
