The answer is: Kaopectane.
Kaopectate is a medication for the treatment of mild diarrhea.
First, kaolinite was used as the adsorbent in this medication. Kaolinite is aa layered silicate mineral, with the chemical composition Al₂Si₂O₅(OH)₄.
Now, bismuth subsalicylate is used as the active absorbent in Kaopectate.
Bismuth subsalicylate has the empirical chemical formula of C₇H₅BiO₄.
It described a nucleus surrounded by a large volume of space.
mass of pentane : = 30.303 g
moles of Al₂(CO₃)₃ : = 0.147
<h3>Further explanation</h3>
Given
1. Reaction
C₅H₁₂+8O₂→6H₂O+5CO₂.
45.3 g water
2. 2AlCl₃ + 3MgCO₃ → Al₂(CO₃)₃ + 3MgCl₂
37.2 MgCO₃
Required
mass of pentane
moles of Al₂(CO₃)₃
Solution
1. mol water = 45.3 : 18 g/mol = 2.52
From equation, mol ratio of C₅H₁₂ : H₂O = 1 : 6, so mol pentane :
= 1/6 x mol H₂O
= 1/6 x 2.52
= 0.42
Mass pentane :
= mol x MW
= 0.42 x 72.15 g/mol
= 30.303 g
2. mol MgCO₃ : 37.2 : 84,3139 g/mol = 0.44
mol Al₂(CO₃)₃ :
= 1/3 x mol MgCO₃
= 1/3 x 0.44
= 0.147
The answer is D. Neutral net charge
Answer: B. HCl(g)+H2O(I)—>H3O+(aq)+Cl-(aq)
D. CO2(g)+2H2O(I)—>HCO3-(aq)+H3O+(aq)
