Answer:

The correct answer is option A, that is, the organic layer.

Explanation:

One knows that non-polar solvent dissolves non-polar substances and the polar solvent dissolves polar substances, that is, like dissolved like. The toluic acid or benzoic acid refers to the carboxylic acids, which are non-polar or are very less polar in characteristics.  

Therefore, they possess the tendency to remain in the organic solvent, which is non-polar like diethyl ether. The toluic acid's or benzoic acid's non-polar characteristic is because of the existence of huge hydrophobic rings of benzene. Hence, the correct answer is option A, that is, the organic layer.

How would it have been if particles of matter had no space?
iragen [17]

Answer:

Matter is made of small particles of atoms or molecules. ... The particles in the solid are touching with very little space between them. The particles in a liquid usually are still touching but there are some spaces between them. The gas particles have big distances between them.

The chemical equilibrium is given:
Kryger [21]

The volume of NO₂=6.25 L

<h3>Further explanation</h3>

Avogadro's stated :

<em>In the same T,P and V, the gas contains the same number of molecules  </em>

So the ratio of gas volume = the ratio of gas moles  

\tt \dfrac{V_1}{V_2}=\dfrac{n_1}{n_2}

the volume of each gas (in a container of volume 10L) :

Total mol=10+10+20=40 mol

  • NO :

\tt \dfrac{10}{40}\times 10=2.5~L

  • O₂ :

\tt \dfrac{10}{40}\times 10=2.5~L

  • NO₂ :

\tt \dfrac{20}{40}\times 10=5~L

NO₂ (has increased by 25%) :

\tt 0.25\times 5~L=1.25\\\\new~volume=5+1.25=6.25

  • O₂ :

\tt \dfrac{10}{20}\times 6.25=3.125

  • NO :

\tt \dfrac{10}{20}\times 6.25=3.125

If a sample of 0.150 g of kcn is treated with an excess of hcl, calculate the amount of hcn formed in grams.
blondinia [14]
<h2> The amount of Hcn  formed in grams  is = 0.06223 grams</h2><h3> calculation</h3>

write the equation for reaction

that is;  KCn + HCl → KCl + HCn

 step 1:find the moles of KCn reacted

moles of KCn = mass of KCn/molar mass of KCn( 65.12 g/mol)

= 0.150 g/ 65.12 g/mol =2.303 x10^-3  moles

step 2: use the mole ratio between KCn :HCn  which is 1:1  to determine the moles of HCn   which is also  2.303 x 10^-3 moles

step 3: find the mass  of HCn =moles of HCn  x molar mass of HCn

= 2.303 x10^-3 x 27. 02 =0.06223 grams
