**Answer:**

The correct answer is** **<em>**d. The nucleoside triphosphates have the sugar deoxyribose; ATP has the sugar ribose.**</em>

**Explanation:**

The nucleoside triphosphates are components of DNA (deoxyribonucleic acid) so they are composed by a nitrogenous base (adenine, guanine, thymine or cytosine) and a **deoxyribose sugar**. In contraposition, ATP (adenosine triphosphate) is composed by the nitrogenous base adenine and a **ribose sugar **along with three phosphates groups. Unlike ribose, deoxyribose is a 5-carbon sugar which lack of an oxygen atom in C2 position.

**Answer:**

Joule-Thomson coefficient for an ideal gas:

**Explanation:**

Joule-Thomson coefficient can be defined as change of temperature with respect to pressure at constant enthalpy.

Thus,

Also,

Also, is defined as:

Acoording to defination, the ethalpy is constant which means

For an ideal gas,

So,

Thus, ≠0. So,

To obtain number of atoms, multiply number of moles by the number of molecules per mole (Avogadro's number) and by the number of atoms per <u>**molecule **</u>(<u>**in this case, there are six if you count them in CH3OH**</u>). Therefore, 1.44 x 10^25 atoms in 128 grams of CH3OH.

**Answer:**

There would be 25 moles

**Explanation:**

This is the equation for water (synthesis):

2H₂ + O₂ → 2H₂O

Since there are 25 moles of water, the moles of hydrogen gas will have 25 moles.
