A camel hump contains 12 kg of triacyclglycerols,
a) Given that there are 0.491 moles of ATP per gram of fat, how many moles of ATP could be produced by the fat in the camel hump?
______moles
b) If the hydrolysis of ATP releases 7.3 kcal/mole, how many kilocalories are produced by the utilization of the fat?
______kcal
The answer is 5892 moles of ATP will be produced from 12 kg of triacyclglycerols, and 43012 kcal energy will be generated by the utilization of the fat .
What are Triacyclglycerols ?Triacylglycerols are formed by linking fatty acids with an ester linkage to three alcohol groups in glycerol.
Triacylglycerols are the form in which fat energy is stored in adipose tissue.
A camel hump contains 12kg = 12000 gm of Triacyclglycerols
a) It is given that there are 0.491 moles of ATP per gram of fat ,
So for 12000 gm of fat in camel hump 12000 * 0.491 moles of ATP will be produced .
= 5892 moles
Therefore Answer is 5892 moles .
If Hydrolysis of ATP releases 7.3 kcal/mole
so 5892 moles will produce 5892 * 7.3 kcal
=43012 kcal energy will be generated by the utilization of the fat.

Determine the volume of Oxygen gas produced by decomposition of 2.44g KClO3?
Answer:
0.956 grams O₂ or
0.956 milliliters O₂ or
9.56 x 10⁻⁴ L O₂
Explanation:
If the reactant were to decompose completely, the entire balanced reaction would look like this:
2 KClO₃ --> 2 K(s) + Cl₂(g) + 3 O₂(g)
To find the answer, (1) convert the grams of KClO₃ to moles (via molar mass from periodic table), then (2) convert moles KClO₃ to moles O₂ (via mole-to-mole ratio from balanced equation), then (3) convert moles O₂ to grams (via molar mass from periodic table).
Molar Mass (KClO₃) = 39.098 g/mol + 35.453 g/mol + 3(15.999) g/mol
Molar Mass (KClO₃) = 122.548 g/mol
Molar Mass (O₂) = 2(15.999) g/mol
Molar Mass (O₂) = 31.998 g/mol
2.44 g KClO₃ 1 mole KClO₃ 3 moles O₂ 31.998 g
-------------------- x -------------------------- x -------------------- x ------------------------
122.548 g 2 moles KClO₃ 1 mole O₂
= 0.956 grams O₂
= 0.956 milliliters O₂
= 9.56 x 10⁻⁴ L O₂
**The prompt askes to determine the volume. As far as I know, there is no easy way to find liters/milliliters with the given information. As such, I found the mass of O₂ instead. Technically, grams is equal to milliliters, so this may be what you are looking for. Then, you can convert from milliliters to liters by dividing by 1,000 (if necessary). **

Relationship between enthalpy and entropy
The relationship between enthalpy (ΔH) and entropy (ΔS) is given by Gibs free energy.
ΔG = ΔH - TΔs
When ΔH < 0 and Δs < 0, ΔG = -ve (-ΔH, - Δs) (for lower temperature)
Also, when ΔH < 0 and Δs = +, ΔG = -ve (-ΔH, +Δs) (for all temperature)
When ΔH > 0 and Δs < 0, ΔG = -ve (+ΔH, - Δs) (for higher temperature)
