As an EPA scientist studying catalytic converters and urban smog, you want to find Kc for the following reaction:2NO₂(g) ⇄ N₂(g) + 2O₂(g) Kc = ?Use the following data to find the unknown Kc:1/2 N₂(g) + 1/2 O₂(g) ⇄ NO(g) Kc = 4.8×102NO₂(g) ⇄ 2NO(g) + O₂(g) Kc = 1.1 ×10⁻⁵
Answers
The equilibrium constant Kc, for the reaction 2 NO₂(g) ⇌ N2(g) + 2O₂(g) is 4.77 × 10¹³.
What is Kc?The equilibrium constant, Kc, is the ratio of the equilibrium concentrations of products over the equilibrium concentrations of reactants each raised to the power of their stoichiometric coefficients.
We are to determine the equilibrium constant, Kc for the reaction
2 NO₂(g) ⇌ N2(g) + 2O₂(g)
The equilibrium constant, Kc for this reaction is given by
2 NO2(g) ⇌ N2(g) + 2 O2(g)
(1) 1/2 N2(g) + 1/2 O2(g) ⇌ NO(g) Kc = 4.8 × 10 −10
(2) 2 NO2(g) ⇌ 2NO(g) + O2(g) Kc = 1.1 × 10−5
To create the first reaction from the two provided reactions, multiply one of them by two, switch the reactants and products, and then sum the results.
(1): 1/2 N2(g) + 1/2 O2(g) ⇌ NO(g) / x2
N2(g) + O2(g) ⇌ 2 NO(g) / switch reactants with products (equivalent to multiply by -1)
2 NO(g) ⇌ N2(g) + O2(g)
(2): 2 NO2(g) ⇌ 2NO(g) + O2(g)
Adding them you get:
2 NO(g) + 2 NO2(g) ⇌ 2NO(g) + O2(g) + O2(g)
After eliminating NO in both sides:
2 NO2(g) ⇌ 2NO(g) + O2(g)
Once the reaction has created, everything you multiplied by the reactions must now be done in the constant rather than the exponent. If you combine reactions, you multiply the constants by one another, which results in:
Kc = (4.8 × 10 −10)^(2*(-1)) * 1.1 × 10−5 = 4.8x10^13

Answers
The molarity of the NaOH(aq) solution is 0.156 M.
The balanced equation for the reaction between sulfuric acid and sodium hydroxide is H₂SO₄(aq) + 2NaOH(aq) → Na₂SO₄(aq) + 2H₂O(l). From the balanced equation, it can be deduced that the mole ratio of NaOH to H₂SO₄ is 2:1. Hence, the moles of H₂SO₄ reacted = Molarity of H₂SO₄ × Volume of H₂SO₄ used in liters = 0.220 M × 0.03230 L = 0.007106 moles.
Using mole ratio, the moles of NaOH reacted = 2 × 0.007106 = 0.01421 moles. Molarity of NaOH = Moles of NaOH / Volume of NaOH used in liters= 0.01421 moles / 0.04630 L = 0.306 M or 0.156 M (rounded off to three significant figures). Thus, the molarity of the NaOH(aq) is 0.156 M.

a face-centered cubic cell contains x atoms at the corners of the cell and y atoms at the faces. what is the empirical formula of the solid?
Answers
The empirical formula of the solid can be represented as x:y.
The empirical formula of the solid is determined by the ratio of the atoms found at the corners and faces of the face-centered cubic cell.
Since the number of atoms at the corners is represented by x, and the number of atoms at the faces is represented by y, then the empirical formula of the solid can be represented as x:y.
For example, if a face-centered cubic cell contains 2 atoms at the corners and 6 atoms at the faces, then the empirical formula of the solid can be written as 2:6, or 1:3.
The empirical formula of the solid, it is necessary to first determine the total number of atoms that make up the cell.
This can be done by multiplying the number of atoms at the corners (x) by 8, since there are 8 corners in a face-centered cubic cell, and adding the result to the number of atoms at the faces (y).
This total number of atoms can be represented as T, and can be written as T = 8x + y.
The empirical formula of the solid is then determined by dividing the number of atoms at the corners (x) and faces (y) by the total number of atoms (T). This calculation can be written as x/T and y/T.
Therefore, the empirical formula of the solid is determined by the equation x/T:y/T.
For example, if a face-centered cubic cell contains 2 atoms at the corners and 6 atoms at the faces, then the total number of atoms in the cell is 14 (8x2 + 6).
Therefore, the empirical formula of the solid can be calculated as 2/14:6/14, or 1:3.
The empirical formula of the solid in a face-centered cubic cell can be determined by,
calculating the total number of atoms in the cell (8x + y), and then dividing the number of atoms at the corners (x) and faces (y) by this total number. The result is the empirical formula of the solid, which is represented as x:y.

In a parallel circuit, what happens to the overall current of the circuit os the number or recivers (and thus the number of branches) is doubled?
Answers
In a parallel circuit, the overall current of the circuit increases when the number of receivers (and thus the number of branches) is doubled.
In a parallel circuit, the current has multiple paths to flow through. Each receiver or branch in the circuit offers a separate path for the current to follow. As a result, the total current flowing into the circuit is divided among the branches. According to Kirchhoff's current law, the total current entering a junction in a circuit is equal to the sum of the currents flowing through each branch. Therefore, when the number of branches is doubled, the total current entering the junction will also double. To put it simply, adding more branches in a parallel circuit increases the number of paths available for the current to flow, reducing the resistance and resulting in an increase in the overall current.

Si tenemos una solución de ácido láctico 0.025M con un pH = 2.75. ¿Cuál es la constante de equilibrio Ka?
Answers
Answer:
La constante de equilibrio Ka del ácido láctico es 1.38x10⁻⁴.
Explanation:
El ácido láctico es un ácido débil cuya reacción de disociación es la siguiente:
CH₃CHOHCOOH + H₂O ⇄ CH₃CHOHCOO⁻ + H₃O⁺ (1)
0.025M - x x x
La constante de acidez del ácido es:
\( Ka = \frac{[CH_{3}CHOHCOOH^{-}][H_{3}O^{+}]}{[CH_{3}CHOHCOOH]} \)
Sabemos que la concentración del ácido inicial es:
[CH₃CHOHCOOH] = 0.025 M
Y que a partir del pH podemos hallar [H₃O⁺]:
\( pH = -log[H_{3}O^{+}] \)
\( [H_{3}O^{+}] = 10^{-pH} = 10^{-2.75} = 1.78 \cdo 10^{-3} M \)
Debido a que el ácido se disocia en agua para producir los iones CH₃CHOHCOO⁻ y H₃O⁺ de igual manera (según la reacción (1)), tenemos:
[CH₃CHOHCOO⁻] = [H₃O⁺] = 1.78x10⁻³ M
Y por esa misma disociación, la concentración del ácido en el equilibrio es:
\( [CH_{3}CHOHCOOH^{-}] = 0.025 M - 1.78 \cdo 10^{-3} M = 0.023 M \)
Entonces, la constante de equilibrio Ka del ácido láctico es:
\( Ka = \frac{[CH_{3}CHOHCOOH^{-}][H_{3}O^{+}]}{[CH_{3}CHOHCOOH]} = \frac{(1.78 \cdo 10^{-3})^{2}}{0.023} = 1.38 \cdot 10^{-4} \)

Answers
80 molecules of \(NH_{3}\) will be formed if 60 molecules of \(N_{2}H_{4}\) decomposes into \(N_{2}\) and \(NH_{3}\)
What are molecules?The smallest particle of a substance has all of the physical and chemical properties of that substance. Molecules are made up of one or more atoms.
Just balance the reaction:
