Answer:
0.66atm
Explanation:
Based on the reaction:
NH₄HS(s) ↔ NH₃(g) + H₂S(g)
The equilibrium constant, Kp, is defined as:
Kp = 0.11 = 
As moles of gas produced for NH₃(g) and H₂S(g) are the same, it is possible to write:
That means pressure of NH₃(g) is 0.33atm and H₂S(g) is, also, 0.33atm. Thus, total pressure is:
0.33atm×2 = <em>0.66atm</em>

The codeine percentage strength of the solution is 20%
- The term "percent strength" describes the proportion of a material that has dissolved in a given volume of liquid.
- Knowing how parts relate to wholes is the secret of % strength: A percent is equal to x parts out of 100 overall.
<h3>Meaning of percentage strength</h3>
- The amount of a liquid is often measured, and the % strength tells you how many parts by volume of the active ingredient are present.
- 100 parts by volume are included in the total volume of the solution or liquid preparation.
<h3>How do you determine a solution's strength?</h3>
Mass of solute times strength of solution(g) Amount of the solution(L)
- The amount of solute dissolved in grams per liter of the solution is used to determine the solution's strength.
- It stands for the solution's potency or concentration.
- It uses grams per liter to express.

Answer:
Molarity of HCl = 1.6M
Explanation:
The chemical reaction equation is;
HCl(aq) + NaOH(aq) —> NaCl(aq) + H2O(l)
Now, molarity = number of moles/volume
Thus, for NaOH, we have;
Number of moles = molarity × volume = 2M × (20/1000) L
Number of moles = 0.04 moles
Using the coefficients in the chemical equation above, we can find the corresponding number of moles for HCl.
Number of moles of HCl = 0.04 moles NaOH × (1 mole of HCl/1 mole of HCl) = 0.04 moles of HCl
Thus;
Molarity of HCl = 0.04/(25/1000)
Molarity of HCl = 1.6M
Answer:
Fractional distillation is the process by which oil refineries separate crude oil into different, more useful hydrocarbon products based on their relative molecular weights in a distillation tower.
