6. The central selenium atom in selenium hexafluo-

serg [7]2 years ago
5 0

Given what we know, we can confirm that when forming an expanded octet, selenium hexafluo ride will hold 6 pairs of shared electrons around its center selenium atom.

<h3>What is an expanded octet?</h3>
  • An expanded octet is when an atom can hold more than 8 valence electrons in its outer shell.
  • This is possible for those elements in period four of the periodic table.
  • Elements that are capable of this form what we call hypervalent compounds.

Therefore, given that during an expanded octet formation, the central atom is capable of holding more than 8 valence electrons in its outer shell, the central atom of a selenium hexafluo ride compound will have 12 electrons being shared, which results in 6 pairs, making C the correct answer.

When the reaction A → B + C is studied, a plot 1/[A]t vs. time gives a straight line with a positive slope. What is the order of
zloy xaker [14]

Answer:

Second order

Explanation:

Given that:

When the reaction A → B + C is studied, a plot 1/[A]t vs. time gives a straight line with a positive slope.

From the integration method for the second order of reaction.

Suppose that:

rate = k₂[A]²

∴

\dfrac{1}{A}=\dfrac{1}{A_0}+k_2t

Therefore, a plot of the linear function \dfrac{1}{A} versus t will be linear with a positive slope k₂ and the intercept on the concentration axis will be \dfrac{1}{A_o}

The linear plot for a second order reaction can be seen in theimage attached below.

What is the mass prevent of manganese (mn) in potassium permanganate (KMnO4)​
oksian1 [2.3K]

Answer:

               Mass percent of Mn is 34.76 %

Explanation:

                    <em>Mass percent</em> of an element is the mass of that element divided by the total mass of the elements forming that compound (or molecular mass.

So,

Mass percent of Mn will be given as,

          %Mn  =  Atomic Mass of Mn / Molecular Mass of KMnO₄ × 100

So,

Atomic Mass of Mn  =  54.94 g/mol

Molecular Mass of KMnO4  =  158.034 g/mol

Putting values in above formula,

          %Mn  =  54.94 g/mol ÷ 158.034 g/mol × 100

          %Mn  = 34.76 %
