Answer:
96,532,000,000,000,000,000,000 ions.
Explanation:
- Assume the highest concentration of HCl in the stomach (160 mmol/L) that is in the canaliculi.
- This means that 1.0 L of the stomach acid contains 0.160 mol.
- Every 1.0 mole of HCl contains Avogadro’s number of molecules (6.022 x 10²³) molecules.
- Every 1.0 molecule of HCl contains 1.0 H⁺ ion.
<u><em>Using cross multiplication:</em></u>
1.0 mole of HCl → 6.022 x 10²³ H⁺ ions.
0.160 mole of HCl → ??? H⁺ ions.
∴ The no. of H⁺ ions in 1 liter of stomach acid = (6.022 x 10²³ H⁺ ions)(0.160 mole of HCl) / (1.0 mole of HCl) = 9.6352 x 10²² ions = 96,532,000,000,000,000,000,000 ions.

Explanation : To find the fraction of schottky defects in the given lattice of CsCl,
we use the formula,
![\frac{N_{s} }{N}} = exp ( \frac{-Q_{s}}{2KT} )](https://tex.z-dn.net/?f=%20%5Cfrac%7BN_%7Bs%7D%20%7D%7BN%7D%7D%20%3D%20exp%20%28%20%5Cfrac%7B-Q_%7Bs%7D%7D%7B2KT%7D%20%29)
on solving with the given values ,
![Q_{s}= 1.86 eV](https://tex.z-dn.net/?f=Q_%7Bs%7D%3D%201.86%20eV)
and T as 645 + 273 K and rest are the constants.
![\frac{N_{s} }{N}} = exp ( \frac{-1.86 eV}{2 X (8.62 X 10^{-5}) X (645 +273)} )](https://tex.z-dn.net/?f=%5Cfrac%7BN_%7Bs%7D%20%7D%7BN%7D%7D%20%3D%20exp%20%28%20%5Cfrac%7B-1.86%20eV%7D%7B2%20X%20%288.62%20X%2010%5E%7B-5%7D%29%20X%20%28645%20%2B273%29%7D%20%29)
we get the answer as 7.87 X

Answer:
B. Mixing a solute and a solvent
Explanation:
Hello,
In this case, solutions are defined as liquid homogeneous mixtures formed when two substances having affinity are mixed. It is important to notice that the two substances are known as solute, which is added to other substance that is the solvent. Therefore, answer is B. Mixing a solute and a solvent.
Notice that when two insoluble substances are mixed no solution is formed. Furthermore, if two solutes together or a solute and a precipitate are mixed, no liquid homogeneous solution is formed, as commonly solutes are solid, nevertheless, when liquid, one should have to act as the solvent.
Best regards.
