The term theoretical yield and actual yield should be defined and the reason behind the fact that the actual yield for an experiment be less than the theoretical yield should be determined and whether the actual yield is more than the theoretical yield or not. Concept Introduction: A balanced chemical equation is an equation that contains same number of atoms as well as of each element of reactants and products of reaction. For example, the reaction between lead sulphide and oxygen is as follows: 2 PbS + 3 O 2 → 2PbO + 2SO 2 Reactants Products The limiting reactant in a particular reaction has due to following properties: Limiting reactant completely reacted in a particular reaction. Limiting reactant determines the amount of the product in mole.

Interpretation Introduction
Interpretation:
The term theoretical yield and actual yield should be defined and the reason behind the fact that the actual yield for an experiment be less than the theoretical yield should be determined and whether the actual yield is more than the theoretical yield or not.
Concept Introduction:
A balanced chemical equation is an equation that contains same number of atoms as well as of each element of reactants and products of reaction.
For example, the reaction between lead sulphide and oxygen is as follows:
2 PbS + 3 O2→2PbO + 2SO2 Reactants Products
The limiting reactant in a particular reaction has due to following properties:
Limiting reactant completely reacted in a particular reaction.
Limiting reactant determines the amount of the product in mole.
Learning Goal:
This question reviews the format for writing an element's written symbol. Recall that written symbols have a particular format. Written symbols use a form like this:
35 Cl
17
In this form the mass number, 35, is a stacked superscript. The atomic number, 17, is a stacked subscript. "CI" is the chemical symbol for the element chlorine. A general way to show this form is:
It is also correct to write symbols by leaving off the atomic number, as in the following form:
atomic number
mass number Symbol
35 Cl or
mass number Symbol
This is because if you write the element symbol, such as Cl, you know the atomic number is 17 from that symbol. Remember that the atomic number, or number of protons in the nucleus, is what defines the element. Thus, if 17 protons
are in the nucleus, the element can only be chlorine. Sometimes you will only see 35 C1, where the atomic number is not written.
Watch this video to review the format for written symbols.

As discussed during the lecture, the enzyme HIV-1 reverse transcriptae (HIV-RT) plays a significant role for the HIV virus and is an important drug target. Assume a concentration [E] of 2.00 µM (i.e. 2.00 x 10-6 mol/l) for HIV-RT. Two potential drug molecules, D1 and D2, were identified, which form stable complexes with the HIV-RT.
The dissociation constant of the complex ED1 formed by HIV-RT and the drug D1 is 1.00 nM (i.e. 1.00 x 10-9). The dissociation constant of the complex ED2 formed by HIV-RT and the drug D2 is 100 nM (i.e. 1.00 x 10-7).
Part A - Difference in binding free eenergies
Compute the difference in binding free energy (at a physiological temperature T=310 K) for the complexes. Provide the difference as a positive numerical expression with three significant figures in kJ/mol.
The margin of error is 2%.
Part B - Compare difference in free energy to the thermal…
