Answer:
<h2>ATP, RNA, NAD and DNA.</h2>
Explanation:
A nitrogenous base; it is an organic molecule containing a nitrogen, carbon and other atoms that has the chemical properties of a base that is why they are called as bases. The nitrogenous bases are; i) adenine, ii) guanine, iii) thymine, iv) uracil and v)cytosine.
Adenine is a nitrogenous base which is found in ATP, RNA. NAD, FAD and DNA. adenine pairs with thymine in DNA synthesis.
When the seasons change from winter to spring, the wolves inner layer of fur, which traps air and insulates the wolf from harsh cold temperatures, is shed to keep the wolf cool when the heat starts to come back.
Lattice energy of potassium nitrate (KNO3) = -163.8 kcal/mol
Hydration energy of KNO3 = -155.5 kcal/mole
Heat of solution is the amount of heat absorbed by water when 1 mole of KNO3 is dissolved in it
Heat of solution = Hydration energy - Lattice energy
= -155.5 -(-163.8) = 8.3 kcal/mol
1 kcal/mol = 4.184 kJ/mole
Therefore, 8.3 kcal/mole = 4.184 * 8.3 = 34.73 kJ/mol
Now, 34.73 kJ of heat is absorbed when 1 mole of KNO3 is dissolved
The given 105 kJ of heat would correspond to : 105/34.73 = 3.023 moles of KNO3
Molar mass of KNO3 = 101.1 g/mole
Mass of KNO3 = Molar mass * moles
= 101.1 * 3.023 = 305.63 g = 0.3056 kg
The two ways to make a saturated solution are 1 reducing the temperature of the solution and Adding more solute.<span> </span>
