Weakly basic drugs behaves different from acidic drugs which is discussed below.
<h3><u>Explanation</u>:</h3>
Weakly basic drugs are those drugs which have an amine group associated with them. They are able to gain a proton to be come positively charged.
So drugs like quinine, ephedrine and aminopyrine which are basic got completely ionised in stomach.
The stomach can absorb those compounds which are lipid soluble. The acidic drugs like alcohols, Salicylic acid, aspirin, thiopental, secobarbital and antipyrine etc which are acidic gets absorbed by means of <em>diffusion</em> through the membrane.
But the basic drugs have charges on them which makes them lipophobic. So they cannot get absorbed through stomach. However weakly basic drugs sometimes get absorbed depending on their ionisation extent.
The rest goes to small intestine which has basic environment and there they gets absorbed via diffusion or facilitated diffusion.
Answer:
1.274 moles
Explanation:
The equation for the reaction can be represented as follows:
⇄ 
+ 
K = 0.060
K = ![\frac{[PCl_3][Cl_2]}{[PCl_5]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BPCl_3%5D%5BCl_2%5D%7D%7B%5BPCl_5%5D%7D)
Concentration of = 
Concentration of = 
Concentration of = 0.398 moles
If we construct an ICE table for the above equation; we have:
⇄ +
Initial 0.398 0 0
Change - x + x + x
Equilibrium (0.398 - x) x x
K =
K = ![\frac{[x][x]}{[0.398-x]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Bx%5D%5Bx%5D%7D%7B%5B0.398-x%5D%7D)
K = 
0.060 =
0.06(0.398-x) = x²
0.02388 - 0.060x = x²
x² + 0.060x - 0.02388 = 0 (quadratic equation)
a = 1; b= 0.06; c= -0.02388
Using quadratic formula;
= 
= 
= 
= 
= 
= 
or 
= 
or 
= 0.1274 or -0.1874
We go by the positive value which says:
[x] = 0.1274 M
number of moles = 0.1274 × 10.0
= 1.274 moles
∴ the number of moles of Cl₂ produced at equilibrium = 1.274 moles
Answer:
IT IS D because lights are heated and it gives light!
Organic fertilizers are made from mined rock minerals, and natural plant and animal materials. They include ingredients like manure, guano, dried and powdered blood, ground bone, crushed shells, finely pulverized fish, phosphate rock, and wood.
Inorganic fertilizer is synthetic, comprised of minerals and synthetic chemicals. Most of the minerals in inorganic fertilizer are mined from the earth, and balanced inorganic fertilizers are high in all three macronutrients and can contain ammonium sulfate, magnesium sulfate, and potassium chloride.
