Change the bond between the two carbon atoms in each molecule to a double or triple bond as needed to complete the structure. If

the bond should remain a single bond, then you do not need to do anything to the bond. Do not change any other bonds in the molecules.

Answer:

Your question is complex, because I think you wrote it wrong.

Although in front of this what I can help you is that the carbons are associated between a single, double or triple union.

This depends on whether they are attached to more or less carbons or hydrogens, the carbons have the possibility of joining 4 radicals, both other carbons and hydrogens.

Simple junctions talks about compound organisms called ALKANS.

The double unions, in organic these compounds are called as ALQUENOS.

And as for the tertiary unions, the organic chemistry names them as ALQUINOS.

These compounds that we write, a simple union, the less energy, the less this union, that is why the triple bond is the one that contains the most energy when breaking or destroying it in a reaction.

Explanation:

In a chemical compound the change of these unions if we modified them we would generate changes even in the classifications naming them as well as different compounds and not only that until they change their properties

Covalent bonding is the ____ of electrons​
taurus [48]

Answer: sharing

Reason: They do this to gain stability. The reason they don’t actually transfer is because the difference in electronegativity values are above a certain value.

An aqueous KNO3 solution is made using 72.5 g of KNO3 diluted to a total solution volume of 2.00 L. Calculate the molarity, mola
Sonja [21]

Answer:

The molarity is 0.359\frac{moles}{L}

The molality is 0.354 \frac{moles}{kg}

The mass percent of the solution es 3.45%

Explanation:

Molarity is a unit of concentration that indicates the amount of moles of solute that appear dissolved in each liter of the mixture. It is determined by:

Molarity (M)=\frac{number of moles of solute}{volume}

Being:

  • K: 39 g/mole
  • N: 14 g/mole
  • O: 16 g/mole

The molar mass of KNO₃ is:

KNO₃=  39 g/mole + 14 g/mole + 3*16 g/mole= 101 g/mole

You can apply the following rule of three: if 101 grams of KNO₃ are present in 1 mole, 72.5 grams in how many moles are present?

moles of KNO_{3}=\frac{72.5 grams*1 mole}{101 grams}

moles of KNO₃= 0.718

So you have:

  • moles of KNO₃= 0.718
  • volume= 2 L

Applying this quantity in the definition of molarity:

molarity=\frac{0.718 moles}{2 L}

Molarity= 0.359\frac{moles}{L}

<u><em>The molarity is 0.359</em></u>\frac{moles}{L}<u><em></em></u>

Molality is a way of measuring the concentration of solute in solvent and indicates the amount of moles of solute in each kilogram of solvent.

Then the molality is calculated by:

Molality=\frac{moles of solute}{mass of solvent in kilograms}

Density is defined as the property that matter, whether solid, liquid or gas, has to compress in a given space. That is, it is the amount of mass per unit volume. So, if the density of 1.05 g / mL for the solution indicates that in 1 mL of solution there are 1.05 grams of solution, in 2000 mL (where 2L = 2000 mL, because 1 L = 1000mL) how much mass is there?

mass=\frac{2000 mL*1.05 grams}{1 mL}

mass= 2100 grams

Since mass solution = mass water + mass KNO₃

then mass water = mass solution - mass KNO₃

Being mass solution 2100 grams and mass KNO₃ 72.5 grams, and replacing you get: mass water= 2100 grams - 72.5 grams

mass water= 2,027.5 grams

Then, being:

  • moles of KNO₃= 0.718
  • mass of solvent in kilograms= 2.0275 kg (being 2,027.5 grams= 2.0275 kilograms because 1,000 grams= 1 kilogram)

Replacing in the definition of molality:

molality=\frac{0.718 moles}{2.0275 kg}

molality= 0.354 \frac{moles}{kg}

<u><em>The molality is 0.354 </em></u>\frac{moles}{kg}<u><em></em></u>

The mass percent of a solution is the number of grams of solute per 100 grams of solution. Then the mass percent is the mass of the element or solute divided by the mass of the compound or solute and the result of which is multiplied by 100 to give a percentage.

mass percent=\frac{mass of solute}{mass of solution} *100

So, in this case:

mass percent=\frac{72.5 grams}{2100 grams} *100

mass percent= 3.45 % KNO₃ by mass

<u><em>The mass percent of the solution es 3.45%</em></u>
