Isomerism Questions and Answers

Quantum numbers arise naturally from the mathematics used to describe the possible states of an electron in an atom. The four quantum numbers, the principal quantum number (n), the angular momentum quantum number (), the magnetic quantum number (me), and the spin quantum number (ms) have strict rules which govern the possible values. Identify all allowable combinations of quantum numbers for an electron. n = 4₁ l = 4, m₁ = − 1, m, = + 1/ n=2, = 0, me = 0, ms = 1 n = 3, l = -2, me = -2, ms = + 1/2 n = 4, C = 3, m² = 4, m₁ = = ²/ n = 5₁ € = 3, me = 1, ms == // n = 3,6 = 2, me = -2, ms = 1/2

Suppose there is a gaseous mixture of nitrogen and oxygen. If the total pressure of the mixture is 450 mmHg, and the partial pressure of nitrogen is 260 mmHg, calculate the partial pressure of oxygen in the mixture using Dalton's law. partial pressure: mmHg

In a cycle of copper experiment, a student first reacts a piece of copper metal with nitric acid to produce copper(II) nitrate (Cu(NO3)₂) solution. The student then performs various reactions which transform the copper ions into a series of different copper compounds and complexes. Finally, the last reaction reduces the copper ions back to elemental copper metal. Copper atoms are conserved throughout the process. If the initial step of the experiment produces 5.14 mL of 1.66 M Cu(NO3)2, what is the theoretical yield of solid copper (Cu) that can be recovered at the end of the experiment?
