Answer:

Four electrons are bounded by eight electrons

and the bond order = 4/3

Explanation:

The molecular ion has 24 valence electrons and The SN of N in the central of the structure is = 3 according to VSEPR Theory. and  this depicts trigonal planar geometry about the central nitrogen also this corresponds to sp^2 hybridization of the valence orbital of the atom N.

The 6 valence electrons are shared between N and O's, while the 2p orbital of Nitrogen will combine with the 2p orbital on each oxygen atoms in order to form four (4) π molecular orbitals. the binding orbital is occupied by a pair of electrons. Four electrons are bounded by eight electrons

and the bond order = 4/3

Explanation:

Step 1: Write the balanced equation for the decomposition of calcium carbonate

CaCO₃(s) ⇒ CaO(s) + CO₂(g)

Step 2: Convert 260.0 °C to Kelvin

We will use the following expression.

K = °C + 273.15 = 260.0 + 273.15 = 533.2 K

Step 3: Calculate the moles of CO₂ produced

We will use the ideal gas equation.

P × V = n × R × T

n = P × V/R × T = 1 atm × 48.0 L/0.0821 atm.L/mol.K × 533.2 K = 1.10 mol

Step 4: Calculate the moles of CaCO₃ that reacted to produce 1.10 moles of CO₂

The molar ratio of CaCO₃ to CO₂ is 1:1. The moles of CaCO₃ that reacted are 1/1 × 1.10 mol = 1.10 mol.

Step 5: Calculate the mass corresponding to 1.10 moles of CaCO₃

The molar mass of CaCO₃ is 100.09 g/mol.

1.10 mol × 100.09 g/mol = 110 g

Answer:

Most solids in solution exhibit a general trend of increasing solubility with increasing temperature.

A seed crystal may be added to a supersaturated solution to precipitate excess solute.

Explanation:

For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions(Lumen Learning).

When a seed crystal is added to a supersaturated solution, excess solute begin to precipitate because  the seed crystal now furnishes the required nucleation site where the excess dissolved crystals now begin to grow.

Explanation:

Step 1: Write the balanced equation

3 KOH + H₃PO₄ ⟶ K₃PO₄ + 3 H₂O

Step 2: Calculate the moles corresponding to 89.7 g of KOH

The molar mass of KOH is 56.11 g/mol.

89.7 g × 1 mol/56.11 g = 1.60 mol

Step 3: Calculate the moles of H₃PO₄ needed to react with 1.60 moles of KOH

The molar ratio of KOH to H₃PO₄ is 3:1. The moles of H₃PO₄ needed are 1/3 × 1.60 mol = 0.533 mol.

Step 4: Calculate the mass corresponding to 0.533 moles of H₃PO₄

The molar mass of H₃PO₄ is 97.99 g/mol.

0.533 mol × 97.99 g/mol = 52.2 g

When vinegar and baking soda are combined a mixture is produced which is carbon dioxide. A gas is released.

Explanation:

Answer: B I think, I'll put my reasoning below.

Explanation:

It's not A because removing N2 would only shift the equation the opposite way.

It's not C and D because I don't think those affect the specific amount of each reactant/product produced. I think temperature only affects the speed at which the reaction is performed, which won't affect anything in this case.

Removing the ammonia as it forms is the correct answer to produce the maximum possible NH₃.

It is an industrial process for manufacturing ammonia by reaction of nitrogen with hydrogen.

N₂+3H₂ ⇌ 2NH₃

The reaction is reversible and exothermic

To answer this question we will consider all the options and answer

Option D ) Increasing Temperature

Haber's process requires an optimal temperature of 450°C ,on Increasing temperature the yield of ammonia gets slow down.

Option C) Decreasing Pressure

Haber's Process requires high pressure to drive the reaction , higher the pressure more is the yield.

Option A ) Removing the N₂ as it forms , on removing  N₂ the reaction will drive on the reverse side hence low yield of NH₃ .

Option B) Removing the NH₃ as it forms , this can actually increase the yield as removing the ammonia will lead to shift the equilibrium and therefore increasing the yield.

Therefore Option B ,  Removing the ammonia (NH₃) as it forms is the correct answer to produce the maximum possible NH₃.

Answer:

Rippling fountain

Explanation:

The option A describes an exothermic reaction.

i.e, ΔHt,reactant > ΔHt, product

The reaction in which energy is release during the formation of reaction is called exothermic reaction.

Mathematically,

ΔHf = ΔH(product) - ΔH(reactant)

For exothermic reaction, ΔHt,reactant > ΔHt, product

So,for exothermic reaction, ΔHf is negative.

Where,

ΔHf = Enthalpy of formation of reaction

ΔH(product) = enthalpy of formation of product

ΔH(reactant) = enthalpy of formation of reactant

Answer:

Option D. Carbon monoxide, 4.56 Moles

Explanation:

The balanced equation for the reaction is given below:

Fe₂O₃ + 3CO —> 2Fe + 3CO₂

From the balanced equation above,

1 mole of Fe₂O₃ reacted with 3 moles of CO to produce 3 moles of CO₂.

1. Determination of the limiting reactant.

From the balanced equation above,

1 mole of Fe₂O₃ reacted with 3 moles of CO.

Therefore, 2.54 moles of Fe₂O₃ will react with = 2.54 × 3 = 7.62 moles of CO.

From the calculation made above, we can see that it will take higher amount of CO (i.e 7.62 moles) than what was given (i.e 4.56 moles) to react completely with 2.54 moles of Fe₂O₃. Therefore, CO is the limiting reactant and Fe₂O₃ is the excess reactant.

2. Determination of the maximum amount of carbon dioxide CO₂ produced.

In this case, the limiting reactant will be used since all of it is consumed by reaction.

The limiting reactant is CO and the maximum amount of CO₂ produced can be obtained as follow:

From the balanced equation above,

3 moles of CO reacted to produce 3 moles of CO₂.

Therefore, 4.56 moles of CO will also react to produce 4.56 moles of CO₂.

Thus, the maximum amount of CO₂ produced is 4.56 moles

Summary:

Limiting reactant => carbon monoxide, CO

Maximum amount of carbon dioxide, CO₂ produced = 4.56 moles

Thus, option D gives the correct answer to the question.
