In chemistry, molecular orbital theory is a method for using quantum mechanics to describe the electronic structure of molecules. It was proposed in the early twentieth century. The atomic orbitals combine to form the molecular orbital. The electrons of molecules fill the new energy states of the molecular orbitals in the same way that the energy states of the atomic orbitals are filled.
The number of molecular orbitals produced is always equal to the number of atomic orbitals brought by the combining atoms. Bonding molecular orbitals have less energy than parent orbitals, while antibonding orbitals have more energy.
Bond order is the number of electron bonding pairs that exist between two atoms. A single bond has a bond order of one in a covalent bond between two atoms, a double bond has a bond order of two, a triple bond has a bond order of three, and so on.

Adding ammonium nitrate to an ammonia solution will result in a decrease in the pH of the solution.
Ammonia is a basic compound. In aqueous solution, the lone pair on the nitrogen atom is able to capture a proton, forming the ammonium ion. Ammonium is the conjugate acid of ammonia, and is slightly acidic. Adding ammonium to a solution of ammonia will lower the pH, since the ammonium is acidic.
The HCl and KCl in the system are there to increase the solution's ionic strength, which results in increased pH value.

Write the configuration of a magnesium atom? Will the atom lose or gain electrons? Explain using the idea of stability and energy.
Answer:
[tex]1s^{2} 2s^{2} 2p^{6} 3s^{2}[/tex]
Magnesium will lose 2 electrons.
Explanation:
Looking at a periodic table, magnesium is in the third period and the second group. It would help to look up where atomic orbitals are on the periodic table, but basically, s orbitals are filled in the first two groups. Since magnesium is in the second group, it will just have filled a 3s orbital with two electrons.
Elements in groups 1A, 2A, and 3A especially like to lose electrons to gain stability. Elements want to have a filled valence (outer) orbital with 8 electrons (except for hydrogen and helium) like noble gases. As such, they will lose or gain electrons in the easiest way possible to get a filled valence orbital. Magnesium wants to have the electron configuration of the nearest noble gas, in this case neon, so it will lose 2 electrons to achieve this stability. It takes much less energy to lose 2 electrons than gain 6 to fill its valence orbital, so magnesium will go for the former.

The percent yield of HCl is 85.0%.
In chemistry, yield, also referred to as reaction yield, is a measure of the quantity of moles of a product formed in relation to the reactant consumed, obtained in a chemical reaction, usually expressed as a percentage.
%yield = (actual yield/theoretical yield) x 100
The presence of impurities lowers the actual yield, which lowers the percentage yield. The purity of the reactants influences the percentage yield. Highly pure reactants tend to increase actual yield and, as a result, percentage yield.
A percentage yield greater than 100 percent is only possible if the product is contaminated with impurities or if all of the solvent from the reaction mixture has not been dried off.

a sample of vitamin a, c20h30o, contains 4.0 x 1024 atoms of carbon. how many moles of vitamin a does it represent?
A sample of vitamin a, C20H30O, contains 4.0 x 1024 atoms of carbon. It represents 6.64 mol of vitamin.
A mole is defined as the quantity of a material that contains precisely the Avogadro number of the substance's "elementary entities."
Every material has the same amount of atoms or other particles in a mole. The mole has the following relationship to an element's mass: One mole of carbon-12 atoms weighs 12 grams and has 6.02214076 x 10^23 atoms.The mole concept helps in putting quantitative data about what transpires in a chemical equation on a macroscopic scale.
Number of carbon atoms in the given sample = 4 x 10^24 atoms.
We know that 6.022 x 10^23 carbon atoms = 1 mole (avagardo constant)
So, moles in 4 x 10^24 carbon atoms will be = 4 x 10^24/ 6.022 x 10^23

Calculate ΔH∘rxn for this reaction using standard enthalpies of formation. (The standard enthalpy of formation of liquid pentane is -146.8 kJ/mol.)
Enthalpy change of Pentane (C5H12) that burns is -3,270.5 kJ
Enthalpy change is defined as the difference in enthalpy of total products and reactants, each multiplied by the respective moles. It is expressed as ΔH°rxn
The formula for calculating the enthalpy change of a reaction is:
ΔH°rxn =∑[n x ΔH°f(product) - ∑[n x ΔH°f(reactant)]
The equilibrium reactions are:
C₅H₁₂(l) + 8O₂(g) ⇒ 5CO₂(g) +6H₂O(g)
ΔH°f(CO₂)(g) = -393.5 kJ/mol
ΔH°f(H₂O)(g) = - 241.8 kJ/mol
ΔH°f(C₅H₁₂)(l) = -146.8 kJ/mol
ΔH°f(O₂)(g) = 0 kJ/mol
The equation for the enthalpy change for the above reaction is:
ΔH°rxn =∑[n x ΔH°f(product) - ∑[n x ΔH°f(reactant)]
ΔH°rxn =∑[(n(CO₂) x ΔH°f(CO₂)) + (n(H₂O) x ΔH°f(H₂O)) ]- ∑[(n x ΔH°f(C₅H₁₂)) + (n x ΔH°f(O₂))]
ΔH°rxn =[( 5 x -393.5) + (6 x - 241.8 ) ]- [(1 x -147.8) + (8 x O₂)]
ΔH°rxn = -3,418.3 -(-147.8)
