The solubility of Ar in water at 25 °C is 1.6 ⋅ 10-3 M when the pressure of the Ar above the solution is 1.0 atm. The solubility

adoni [48]

Answer:

SAr = 3.75 E-3 M ≅ 4.0 E-3 M

Explanation:

Henry's law:

Sg = (Kh)*(Pg)

∴ 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

balandron [24]

Answer:

B) weathering and erosion

Explanation:

The two processes responsible for changing metamorphic and igneous rocks into sedimentary rocks is weathering and erosion.

Weathering is the defined as the physical disintegration and chemical decomposition of rocks to form sediments and soils.

Erosion is the removal of weathered materials from the surface of the earth.

The process of erosion and weathering serves to convert igneous and metamorphic rocks into sediments by which a sedimentary rock is formed.

Draw the addition product formed when one equivalent of hcl reacts with the following diene.

pashok25 [27]

Answer:

Major Product = 4-chloro-4-methylcyclohex-1-ene

Explanation:

Alkene are the class of organic compounds which contain one or more double bonds between two carbon atoms. Alkenes are considered most reactive among the unsaturated hydrocarbons and they undergo addition reactions due to high electron density around the double bonds.

In given question it is written that we are provided with one equivalent of HCl while, our compound contains two double bonds (diene) so in selected starting material the HCl will be added across (hydrohalogenation reaction) the substituted double bond because it will give a more stable carbocation (tertiary carbocation) during the reaction course. Hence, as shown in reaction scheme 4-chloro-4-methylcyclohex-1-ene will be the major product.
