Answer:
SAr = 3.75 E-3 M ≅ 4.0 E-3 M
Explanation:
Henry's law:
∴ Sg: gas solubility (mol/L)
∴ Kh: Henry's constant ⇒ Kh Ar = 1.5 E-3 mol/atm.L.....from literature
∴ Pg: Partial pressure of gas on solution (atm)
If Pg = 2.5 atm
⇒ Sg = (1.5 E-3 mol/atm.L)(2.5 atm)
⇒ Sg = 3.75 E-3 M

Answer:
D. Incinerating or incineration
Explanation:
Burning trash to reduce the amount of waste on land is called incineration.
Answer:
1) D. Dissolved Molecule
2) C. 11.30 M
Explanation:
<u><em>Q1:</em></u>
- Glucose (C₆H₁₂O₆) is a non-polar molecule.
- When it is dissolved in water, it will be a dissolved molecule.
- It can not be ionized in water.
- So, the right choice is: <em>D. Dissolved molecule.</em>
<u><em>Q2</em></u>:
- The molarity is the no. of moles of dissolved solute in a 1.0 L of the solution.
<em>M = (n)solute (1000/V (mL) of the solution)</em>
n of LiCl = 2.60 mol, V = 230.0 mL.
∴ M = (n)solute (1000/V (mL) of the solution) = (2.60 mol)(1000)/(230.0 mL) = 11.30 M.
