How do the periodic trends in metallic character compare to those for ionization energy? How do the periodic trends in metallic
character compare to those for ionization energy? Metals tend to have higher ionization energies than nonmetals. Metals tend to have lower ionization energies than nonmetals. Metals and nonmetals tend to have the same ionization energies.
1 answer:
Answer:
Metals tend to have lower ionization energies than nonmetals.
Explanation:
Hello,
Consider the attached picture about periodic trends because it illustrates how ionization energies increase or decrease. As you can see, the higher the metallic character, the lower the ionization energy, thus, metals tend to have lower ionization energies than nonmetals.
Best regards.

<u>Answer:</u> The amount of formed is 469.8 grams.
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
......(1)
Given mass of phosphine = 225 g
Molar mass of phosphine = 34 g/mol
Putting values in equation 1, we get:
The given chemical reaction follows:
Assuming that oxygen gas is present in excess, it is considered as an excess reagent.
Phosphine is considered as a limiting reagent because it limits the formation of product.
By Stoichiometry of the reaction:
4 moles of phosphine produces 1 mole of
So, 6.62 moles of phosphine will produce = of
Now, calculating the mass of by using equation 1:
Molar mass of = 283.9 g/mol
Moles of = 1.655 moles
Putting values in equation 1, we get:
Hence, the amount of formed is 469.8 grams.
Answer:
0.24
Explanation:
We are given that
Rate constant for A=
Rate constant for B,k'=0.0750/s
We have to find the value of equilibrium constant for the reaction
Equilibrium constant, for k=
Using the formula
Hence, the value of the equilibrium constant for the reaction
at this temperature=0.24
