The number of sulfate ions : 2.2 x 10²³
<h3>Further explanation</h3>
Reaction
Al₂(SO₄)₃⇒2Al³⁺+3SO₄²⁻
mol Al₂(SO₄)₃(MW=342,15 g/mol) :
mol of sulfate ions (SO₄²⁻)
1 mol = 6.02 x 10²³ particles (ions, molecules, atoms), so for 0.366 mol :
How am I supposed to help you if there's not picture of what the problem is
Answer:
A. One unpaired electron
B. 5 unpaired electrons
Explanation:
In A ,Fe is in +3 oxidation state and Electronic configuration- [Ar]3d5
And NO2 is a strong field ligand hence it causes pairing in t2g orbitals and results one unpaired electron in dZX orbital.
In B, also Fe is in +3 oxidation state but F is weak field ligand hence causes no pairing of Electrons hence it results 5 unpaired electrons with electronic configuration t2g^3 eg^2
Bonds payable to whomever holds them are called bearer bonds or unregistered bonds.
<h3>What is bearer bond ?</h3>
Bonds that have no registered owners are known as bearer bonds. Instead, the bond is owned by whoever "bears" (or has possession of) it. Bearer bonds, sometimes known as coupons, have coupons that bondholders can detach and present to receive interest payments.
<h3>What are interest payments ?</h3>
An interest rate is the amount of interest that is payable each period stated as a percentage of the amount that was lent, deposited, or borrowed. The principal amount, interest rate, frequency of compounding, and duration of the loan, deposit, or borrowing determine the total amount of interest on a sum that was lent or borrowed.
