Answer: -22.2 kJ
Explanation:
According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.

According to Hess’s law, the chemical equation can be treated as algebraic expressions and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.
(1) 
(2) 
(3) 
Reversing 1 ,2 and 3 and halving 1 and 2 and then adding we get net equation:
(4) 
Therefore, the heat of reaction, ΔH, for the reaction is -22.2 kJ
When palmitate (C16) completely oxidized, net yield is 129 ATP.
There are 7 β-oxidation cycles for palmitate to completely oxidazed.
One β-oxidation (beta-oxidation) cycle produces 1 NADH, 1 FADH2, and 1 acetyl CoA (sea the picture below).
For 7 cycles: 7 NADH, 7 FADH2, and 8 acetyl CoA.
NADH and FADH2 enter Electron Transport System (ETS) cycle to generate 3ATP and 2ATP respectively.
Acetyl CoA enter into tricarboxylic acid cycle (TCA) and each CoA gives 12 ATP.
7 NADH = 7 x 3 = 21 ATP
7 FADH2 = 7 x 2 = 14 ATP
8 acetyl-CoA = 8 x 12 = 96 ATP
Net yield of ATP = 21 ATP + 14 ATP + 96 ATP - 2 ATP (used during conversion of palmitic acid into palmitoyl CoA)
Net yield of ATP = 129 ATP

Answer:True
Explanation:
Water is said to be hard when it contains calcium ions or magnesium ions dissolved in it. These ions are able to react with soap in such a way that the soap is prevented from forming lather with the water. Hard water occurs when water passes over calcium or magnesium bearing minerals and dissolves some of it. Hardness due to the presence of calcium ions can easily be removed by boiling the water.
Answer:
Option B - 2
Explanation:
In Crystal lattices, there are different types of unit cells namely;
- Hexagonal Closest Packed (HCP)
- Face Centred Cubic (FCC)
- Body Centred Cubic (BCC)
- Simple Centred Cubic (SC)
Now, each of them have a coordination number and also number of atoms per unit cell.
For this question, we are restricted to the body-centered cubic (bcc) unit cell which has a coordination number of 8 and contains 2 atoms per unit cell.
