The equilibrium constant of the reaction is 76176.

<h3>What is the equilibrium constant?</h3>

In chemistry, the equilibrium constant is used to show the extent to which we can convert reactants to products in a given chemical process. A large value of the equilibrium constant shows that most of the reactants are converted into products under the given conditions. A small value of the equilibrium constant shows that most of the reactants are not converted into products.

Thus, if we have the reactions;

(1) 1/2 X2(g) + 1/2 Y2(g) ↔ XY(g)

(2) 2XY(g) ↔ X2(g) + Y2(g)

It then follows that;

K1 = [XY]/[X2]^1/2 [Y2]^1/2

K2 =  [XY]^2/[X2] [Y2]

It is clear that;

K2 = (K1)^2

K2 = (276)^2

K2 = 76176

(d) If you have 9.44 g of NazPO4, how many grams of AgNO, will be needed for complete
AlladinOne [14]

30.6 g of AgNO₃

Explanation:

We have the following chemical reaction:

Na₃PO₄ + 3 AgNO₃ → Ag₃PO₄ +  3 NaNO₃

Now we calculate the number of moles of  Na₃PO₄:

number of moles = mass / molecular weight

number of moles of Na₃PO₄ = 9.44 / 164 = 0.06 moles

Now we formulate the following reasoning:

if        1 mole of Na₃PO₄ will react with 3 moles of AgNO₃

then  0.06 moles of Na₃PO₄ will react with X moles of AgNO₃

X = (0.06 × 3) / 1 = 0.18 moles of AgNO₃

mass = number of moles × molecular weight

mass of AgNO₃ = 0.18 × 170 = 30.6 g

What is the best description of bond angles around the carbon atoms of 1-butene?
vampirchik [111]

The best description of bond angles around the carbon atoms of 1-butene is double bonded unsaturated carbon atoms and sp2 hybridized

<h3>What are organic compounds?</h3>

Organic compounds are those organics substances containing carbon and hydrogen only.

Some classes of organic compounds are:

  • Alkanes
  • Alkenes
  • Alkenes

So therefore, the best description of bond angles around the carbon atoms of 1-butene is double bonded unsaturated carbon atoms and sp2 hybridized

Food labels list the amount of carbohydrates, fats, and proteins, but not nucleic acids. why not
garri49 [273]
The structure of the nucleic acids are having three functional groups, namely, sugar, phosphate group and nitrogenous base. The only source of nucleic acids is your human body in the form of DNA and RNA. They are not obtained from the external environment. This is because the only purpose of nucleic acids are containing the genetic information and the transcription of amino acids to form proteins.

Consider the intermediate chemical reactions.
Svetach [21]

Answer:

When the enthalpy of this overall chemical equation is calculated, the enthalpy of the second intermediate equation is halved and the sign on it reversed, to obtain the required enthalpy of overall reaction.

ΔH(overall) = -178.3 kJ

Explanation:

First intermediate equation

Ca (s) + CO₂ (g) + ½O₂ (g) → CaCO₃ (s) ΔH₁ = -812.8 kJ

Second intermediate equation

2Ca (s) + O₂ (g) → 2CaO (s) ΔH₂ = -1269 kJ

Overall Equation

CaO (s) + CO₂ (g) → CaCO₃ (s) ΔH = ?

When the enthalpy for the overall equation is to be calculated, the intermediate reactions are summed up (this is according to Hess' Law and Bon Haber cycle),

But the sum of the intermediate reactions for this case would not give the overall reaction.

But

(Intermediate reaction 1) + ½(- Intermediate reaction 2) = (Overall reaction)

Intermediate reaction 1

Ca (s) + CO₂ (g) + ½O₂ (g) → CaCO₃ (s) ΔH₁ = -812.8 kJ

½(Intermediate reaction 2)

½[2Ca (s) + O₂ (g) → 2CaO (s) ΔH₂ = -1269 kJ]

= Ca (s) + ½O₂ (g) → CaO (s) ΔH₂' = ½ × -1269 kJ = -634.5 kJ

-½(Intermediate reaction 2)

CaO → Ca (s) + ½O₂ (g) ΔH₂" = 634.5 kJ

Ca (s) + CO₂ (g) + ½O₂ (g) → CaCO₃ (s) ΔH₁ = -812.8 kJ

CaO → Ca (s) + ½O₂ (g) ΔH₂" = 634.5 kJ

Overall Equation

CaO (s) + CO₂ (g) → CaCO₃ (s) ΔH = ?

ΔH = ΔH₁ - ½ΔH₂ = ΔH₁ + ΔH₂"

ΔH = -812.8 + 634.5 = -178.3 kJ

When the enthalpy of this overall chemical equation is calculated, the enthalpy of the second intermediate equation is halved and the sign on it reversed, to obtain the required enthalpy of overall reaction.

Hope this Helps!!!
