Number of moles :

n = mass solute / molar mass

n = 20 / 18

n = 1.111 moles

Therefore:

Molarity  =  moles solute / volume

Molarity  = 1.111 / 30 => 0.37 M

If the reaction 2HgO --> 2Hg + O2 is endothermic, which bonds are the strongest?
Alika [10]
  • Endothermic reaction means the reactant side takes heat from surrounding and get decomposed i.e ∆H=-ve
  • If the equation is exothermic then it means the reactant is happy to decompose .But it's not as it's endothermic

Now

  • HgO is Omitted from our solution option.

Hg is a atom so no bonds hence no bond strength occurs.

  • O_2 is a molecule and so it's our answer .

Draw the major organic substitution product(s) for (2R,3S)-2-bromo-3-methylpentane reacting with the given nucleophile. Indicate
Ede4ka [16]

Answer:

The final product of the reaction is (<em>2S,3S</em>)-2-ethoxy-3-methylpentane.

Explanation:

The given reaction undergoes S_{N}2  mechanism in which the nucleophile attacks the backside and it is substituted by the elimination of bromine.

Due to the backside attack of nucleophile , the inverse in stereo-chemistry is observed.

After the substitution of ethoxy group, the configuration is assigned according to the priority it shows clock wise direction(R) - configuration.

When hydrogen faces the front side , it results shows inverse configuration i.e, S- configuration.

The chemical reaction is as follows.
