Determine the number of nh4 nh4 and co32−co32− ions required to form a neutral ionic compound

Answers

Answer 1

The number of NH₄⁺ NH₄⁺ and CO₃⁻² CO₃⁻² ions required to form a neutral ionic compound are 2 and 1 respectively.

A Neutral Ionic Compound means a compound that is made by both positively and negatively charged ions i.e. cations and anions respectively.

NH₄⁺ is called as Ammonium ion formed due to addition of H+ (Proton) in Ammonia and CO₃⁻² is called as Carbonate ion formed with a Trigonal Planar structure.

For a compound having NH₄⁺ and CO₃⁻², a neutral compound can be made by keeping the total charge on the compound to be zero.

Hence, Ammonium carbonate (NH₄) ₂CO₃ is a neutral compound formed by taking 2 NH₄⁺ and 1 CO₃⁻² ions.

So, for the formation of the Neutral compound i.e. Ammonium carbonate (NH₄) ₂CO₃ , 2 NH₄⁺ and 1 CO₃⁻² is needed.

How many grams of CO would be required to generate 635 g CO2

Answers

The amount of CO that would be required to generate 635 g of CO2 will be 404.14 g

Stoichiometric problem

First, let us get the equation of the reaction:

[tex]2CO + O_2 -- > 2CO_2[/tex]

From the equation, we can see that the mole ratio of CO to that of CO2 is 1:1.

635 g of CO2 is to be generated.

Mole of 635 g CO2 = mass/molar mass = 635/44.01 = 14.43 moles

Thus, the equivalent mole of CO required will also be 14.43 moles.

Mass of 14.43 moles CO = moles x molar mass = 14.43 x 28.01 = 404.14 g

Hence, 404.14 g of CO will be required to produce 635 g of CO2

Assuming the salt is sodium chloride, what is the approximate molar concentration of salt in ocean water if the density of ocean water is 1.028 kg/l?

Answers

Molar concentration of Sodium chloride (NaCl) means the number of moles of sodium chloride present in 1L of water.

Molar mass of NaCl = Molar mass of Na + Molar mass of Cl

Molar mass of NaCl = 23 + 35.5

Molar mass of NaCl = 58.5g

∴ 1L of water contains 55.55 moles of water. Hence,

Mass of ocean water = 55.55 × 18 = 999.9g

Since, 1L of ocean water has a mass of 999.9g of which 3.5% is the salt.

hence, (999.9) (0.035) = 34.99g

So, No. of moles of NaCl = Mass of NaCl / 58g NaCl per mol

No. of moles of NaCl = 34.99/58.5

No. of moles of NaCl = 0.59 moles

So, Molar concentration or Molarity would be 0.59 moles present in 1L of solution.

Hence, Molarity or Molar Concentration = Moles of NaCl/ Volume of solution (in L)

Molarity = 0.59/1L

⇒ Molarity = 0.59M

What can happen if the level of the developing liquid is higher than the applied spots in the tlc analysis?

Answers

If the solvent level in the developing jar is deeper than the origin (spotting line) of the TLC plate, the solvent will dissolve the compounds into the solvent reservoir instead of allowing them to move up the plate by capillary action. Thus, you will not see spots after the plate is developed.

What is Thin Layer Chromatography (TLC)?

TLC is a simple, quick, and inexpensive procedure that gives the chemist a quick answer as to how many components are in a mixture. TLC is also used to support the identity of a compound in a mixture when the Rf of a compound is compared with the Rf of a known compound.A TLC plate is a sheet of glass, metal, or plastic which is coated with a thin layer of a solid adsorbent (usually silica or alumina). A small amount of the mixture to be analysed is spotted near the bottom of this plate. The TLC plate is then placed in a shallow pool of a solvent in a developing chamber so that only the very bottom of the plate is in the liquid. This liquid, or the eluent, is the mobile phase, and it slowly rises up the TLC plate by capillary action.As the solvent moves past the spot that was applied, an equilibrium is established for each component of the mixture between the molecules of that component which are adsorbed on the solid and the molecules which are in solution. In principle, the components will differ in solubility and in the strength of their adsorption to the adsorbent and some components will be carried farther up the plate than others. When the solvent has reached the top of the plate, the plate is removed from the developing chamber, dried, and the separated components of the mixture are visualized. If the compounds are coloured, visualization is straightforward. Usually the compounds are not coloured, so a UV lamp is used to visualize the plates. The plate itself contains a fluorescent dye which glows everywhere except where an organic compound is on the plate.

How do different glycosidic bonds contribute to the properties of different sugars?

Answers

When the hemiacetal of a saccharide (or a molecule made from a saccharide) combines with the hydroxyl group of another chemical, such as alcohol, a glycosidic bond, also known as a glycosidic linkage, is formed. Only sugars in cyclic forms, which have an anomeric carbon and can create a glycosidic bond, may do so.

The glucose units of glycogen, the main type of energy storage in animal cells, are connected by glycosidic linkages. They are the bonds that make up the strong exoskeletons of beetles, crabs, and lobsters as well as the cellulose that makes up the woody sections of plants and trees.

A sugar molecule connected to another molecule via an ether group is the outcome of a glycosidic connection. A chemical compound called an ether, which consists of an oxygen atom bound to two carbon atoms, is less reactive than other chemical compounds like alcohols. Glycosides are therefore typically more stable than free sugars.

Write 3–4 sentences to describe how coupling reactions are used to drive an unfavorable chemical reaction.

Answers

The concept of coupling reactions can be more understood knowing that Gibbs free energy is a state function. State function is a property that does not depend on the path taken to arrive to that value

What is Coupling reaction ?

A reaction where the the free energy of a thermodynamically favorable transformation, such as the hydrolysis of ATP, and a thermodynamically unfavorable one, are mechanistically joined into a new reaction (or may be envisaged to be so joined) is known as a coupled reaction.

How do you make an unfavorable reaction favorable?

Chemically unfavorable means non-spontaneous which means Gibbs' free energy change (ΔG) is positive, i.e. ΔG>0.

But we know that ΔG=ΔH−TΔS. Now ΔH and ΔS (enthalpy and entropy change, respectively) are state functions. So ΔG is also a state function.

Catalysts can only change the pathway of a reaction (in most of the cases, by lowering the activation energy of the reaction (Ea)) but after using the catalysts also, the energy states of the reactants and products don't alter. So ΔH and ΔS remain the same as uncatalysed reaction. So ΔG also doesn't change at all. So if the reaction is non-spontaneous, it remains like that.

That means, the thermodynamically unfavorable reaction can't be made favorable by introducing a catalyst.

But changing the temperature to a very high value can make ΔG<0, so the reaction can be made favorable by abruptly increasing temperature.

What are favorable and unfavorable reactions?

Reactions that release energy are energetically favorable. Conversely, reactions in which the products are higher in energy than the reactants require an input of energy to proceed; such reactions are energetically unfavorable

Diffraction lines occur at angles θ such that dsinθ=mλ, where λ is the wavelength and m is an integer.

Notice that for a given order, the line associated with a long wavelength is produced at a greater angle than the line associated with a shorter wavelength.

We take λ to be the longest wavelength in the visible spectrum (538nm) and find the greatest integer value of m such that θ is less than 90°.

That is, find the greatest integer value of m for which mλ<d.

In a combustion chamber, ethane (c2h6) is burned at a rate of 9 kg/h with air that enters the combustion chamber at a rate of 176 kg/h. determine the percentage of excess air used during this process

Answers

The percentage of excess air used during combustion process of ethane will be 37 %.

Burning, also known as combustion, would be a high-temperature highly exothermic chemical process that occurs when an oxidant, typically atmospheric oxygen, interacts with a fuel to generate oxidized, frequently gaseous products in a mixture known as smoke.

Calculation of percentage of air .

[tex]C_{2} H_{6} + (1-x)+a(O_{2} +3.76N_{2} )=bCO_{2} + cH_{2} O + axO_{2} + 3.76dN_{2} .[/tex]

Mair=Mair/Rin

[tex]( MN)O_{2}[/tex] + [tex](MN)N_{2}[/tex]÷ [tex](MN)O_{2}[/tex] + [tex](MN)N_{2}[/tex] +[tex](MN)C_{2} H_{6} .[/tex]

33 . 3.25(1-x) + 28 × 13.16(1-x) ÷ 33 × 3.25(1-x) + 28 × 13.16(1-x). + 30.1

= 176/176+8

X= 0.37

0.37 × 100

X= 37%

Therefore, the percentage of excess air used during combustion process of ethane will be 37 %.

The O2 molecule breaks apart at lower wavelengths than the O3 molecule. What is the main reason for this?

Answers

The main reason for this is Average bond of O₂ is shorter and strong from O₃.

What is ozone?

Ozone is a blue gas composed of three oxygen atoms bonded together.

It occurs naturally high up in the Earth's atmosphere, where it protects the surface from harmful ultraviolet (UV) rays,

UV radiation will dissociate ozone into an oxygen atom and an oxygen molecule.

Ozone molecules are tetrahedral so the bond angle is  109 degree the electrons in the double bond occupy more space that the non-bonding electron pair.

Oxygen has a small size that leads to smaller O-O bond length.

A lone pair of electrons on both the oxygen repel each other leading to weakening of O-O bond.

O3 has longer and weaker bonds than O2, whereas SO2 has shorter and stronger bonds than SO.

Molecular oxygen, O2, is photolyzed by light of 241 nm and has a bond energy of 498 kJ/mol.

The main reason for this is Average bond of O₂ is shorter and strong from O₃.

a balloon filled with .5l of air at sealevel is submerged in the water to a depth that produces a pressure of 3.25 atm. What is the volume of the balloon at this depth

Answers

The balloon is filled with 0.5L of air at sea level and submerged to a depth. Since, there is no change in the Temperature, the process is Isothermal. It is a process in which the temperature T of the given system does not change and remains constant. Hence, ΔT=0

Any system in which the temperature is kept constant is stated as an Isothermal Process. Since, in the given question, Temperature is not changing, hence we can consider it to be an Isothermal Process.

Given:

Pressure at sea level, P₁= 1 atm

Volume at sea level, V₁= 0.5L

Pressure at depth, P₂= 3.25 atm

Volume at depth, V₂= ?

Since, the process is Isothermal, hence,

P₁V₁ = P₂V₂

⇒ 1 × 0.5 = 3.25 × V₂

⇒ V₂ = 0.5/3.25

⇒ V₂ = 0.154L

So, the Volume of balloon at the depth is 0.154L.
