(a)
Interpretation:
Interpret the name of CaH2 is calcium hydride or not.
Concept Introduction:
The more the element is electropositive in nature, more it releases electron and thus its oxidation state is denoted by roman numerical after the name of cation.
For example in CuCl2, Cu having + 2 state and thus the name can be written as copper (ii) chloride.
Hence, charge of element is written as number of charge denoted with roman number.
(b)
Interpretation:
Interpret the name of PbCl2 is lead (iv) chloride or not.
Concept Introduction:
The more the element is electropositive in nature, more it releases electron and thus its oxidation state is denoted by roman numerical after the name of cation.
For example in CuCl2, Cu having + 2 state and thus the name can be written as copper (ii) chloride.
Hence, charge of element is written as number of charge denoted with roman number.
(c)
Interpretation:
Interpret the name of CrI3 is chromium (iii) iodide or not.
Concept Introduction:
The more the element is electropositive in nature, more it releases electron and thus its oxidation state is denoted by roman numerical after the name of cation.
For example in CuCl2, Cu having + 2 state and thus the name can be written as copper (ii) chloride.
Hence, charge of element is written as number of charge denoted with roman number.
(d)
Interpretation:
Interpret the name of Na2 S is disodium sulfide or not.
Concept Introduction:
The more the element is electropositive in nature, more it releases electron and thus its oxidation state is denoted by roman numerical after the name of cation.
For example in CuCl2, Cu having + 2 state and thus the name can be written as copper (ii) chloride.
Hence, charge of element is written as number of charge denoted with roman number.
(e)
Interpretation:
Interpret the name of CuBr2 is cupric bromide or not.
Concept Introduction:
The more the element is electropositive in nature, more it releases electron and thus its oxidation state is denoted by roman numerical after the name of cation.
For example in CuCl2, Cu having + 2 state and thus the name can be written as copper (ii) chloride.
Hence, charge of element is written as number of charge denoted with roman number.

- 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.

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.
