Answer:

The higher the ionization energy, the lower the reactivity.

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to draw a conclusion about the relationship between ionization energy and reactivity, by bearing to mind that the former is the energy the atom needs to lose its electron, this means that the higher the energy, the more difficult is for the atom to do so.

Based on the aforementioned, since the reactivity is related to how likely an atom undergoes a chemical change by losing or gaining electrons, we can say that the reactivity decreases as the ionization energy increase as, again, it is more difficult for the atom to have an excited state allowing its chemical interaction with another substance.

Unfortunately, the "above elements" where not given, so this part could not be solved, however, you can use the attached periodic trend for ionization energy to figure out the correct order, by keeping in mind the previous reasoning.

A gas is collected at 30 Celsius and has a pressure of 200 kPa. What pressure would it exert if the temperature changed to 40 Ce
garik1379 [7]

Answer:

206.6\ \text{kPa}

Explanation:

P_1 = Initial pressure = 200 kPa

P_2 = Final pressure

T_1 = Initial temperature = 30^{\circ}\text{C}

T_2 = Final temperature = 40^{\circ}\text{C}

We have the relation

\dfrac{P_2}{P_1}=\dfrac{T_2}{T_1}\\\Rightarrow P_2=\dfrac{T_2}{T_1}P_1\\\Rightarrow P_2=\dfrac{40+273.15}{30+273.15}\times 200\\\Rightarrow P_2=206.6\ \text{kPa}

The pressure that would be exerted after the temperature change is 206.6\ \text{kPa}.

What if there was an inverse relationship between the temperature and the volume? How do you think the world might be different?
kari74 [83]

If there was an inverse relationship between the temperature and the volume, our daily lives change because in high temperature things will contract.

<h3>What if there was an inverse relationship between the temperature and the volume?</h3>

If there was an inverse relationship between the temperature and the volume then with increasing temperature decrease occur in the volume of a substance. If this type of relationship is present in the world, the objects will contract when the temperature is high and expand when the temperature is low which make the solid materials expand at winter and contract at summer season.

So we can conclude that if there was an inverse relationship between the temperature and the volume, our daily lives change because in high temperature things will contract.
