The equilibrium constant kc of the reaction H2+I2 produces HI is 54.3at430°C. Starting with 6.0moles,of HI moles of HI in 1.0dm^3 reaction vessel, calculate th5 concentration of H2,I2 and HI at equilibrium

Answers

Answer:

[H2] = [I2] = 0.64M; [HI] = 4.72M

Explanation:

Based on the reaction:

H2 + I2 ⇄ 2HI

The K is defined as:

k = 54.3 = [HI]² / [H2] [I2]

Where [] is molar concentration of each reactant at equilibrium

As the initial concentration of HI is 6mol/dm^3 = 6M the equilibrium concentration of each reactant is:

[H2] = X

[I2] = X

[HI] = 6 - 2X

Where X is reaction coordinate

Replacing:

54.3 = [6-2X]² / [X] [X]

54.3X² = 4X² - 24X + 36

0 = -50.3X² - 24X + 36

Solving for X:

X = -1.12. False solution, produce negative concentrations

X = 0.64M. Right solution

Replacing:

[H2] = 0.64M

[I2] = 0.64M

[HI] = 6 - 2*0.64M = 4.72M

Equilibrium concentrations are:

[H2] = [I2] = 0.64M; [HI] = 4.72M

How many moles of potassium Chlorate are needed to produce 15.0 moles of oxygen

Answers

Answer:

10 moles of potassium Chlorate are required to produce 15 mole of oxygen

Explanation:

The balanced chemical equation is

2KClO3(s)→2KCl(s)+3O2(g)

2 moles of potassium Chlorate produce 3 moles of oxygen

Number of moles of potassium Chlorate required to produce 1 mole of oxygen [tex]= \frac{2}{3}[/tex]

Number of moles of potassium Chlorate required to produce 15 mole of oxygen

[tex]= \frac{2}{3} * 15\\= 10[/tex]

10 moles of potassium Chlorate are required to produce 15 mole of oxygen

A. 0.2

B. 0.3

C. 0.225

D. 5.0

E. 2.5

Please help.

Answers

Answer:

D. 5.0

Explanation:

Step 1: Write the balanced equation at equilibrium

2 NO₂(g) ⇄ N₂O₄(g)

Step 2: Calculate the concentration equilibrium constant

The concentration equilibrium constant (Kc) is equal to the product of the concentrations of the products raised to their stoichiometric coefficients divided by the product of the concentrations of the reactants raised to their stoichiometric coefficients.

Kc = [N₂O₄]/[NO₂]² = 0.2 / 0.2² = 5

what the difference between a sodium atom (Na) and a sodium ion (Nal+)

Answers

Answer:

So a sodium atom has the electronic configuration 2,8,1 meaning it has 1 electron on its outer shell. It has a neutral charge since the number of electrons is equal to the number of protons.

A sodium ion is one that has lost the electron on its valence shell. The electronic configuration is 2,8 and it has a positive charge because it has more protons than electrons.

Answer:

[tex]\boxed {\boxed {\sf Number \ of \ electrons \ and \ net \ charge}}[/tex]

Explanation:

Remember that protons have a positive charge of +1 and electrons have a negative charge of -1. Atoms have protons and electrons.

A sodium atom has the electron configuration of 2-8-1. It has 11 electrons and its atomic number (number of protons) is also 11. This means it is a neutral atom because the charges of the electrons (-11) and protons (+11) balance each other out.

However, a sodium ion is different. It loses the 1 valence electron, so it only has 10 electrons. It still has the same atomic number of 11.

It is a not a neutral atom because the charges of the electrons (-10) and protons (+11) do not balance out. It has more protons and a net positive charge of +1. It is a cation or a positively charged ion.

Calculate the specific heat of an unknown metal if it took 58.1 J to increase the temperature of 89.4 g of the metal from 23.4°C to 25.5°C.

Answers

Answer:

[tex]c=0.309\ J/g^{\circ} C[/tex]

Explanation:

The increase in heat, Q = 58.1 J

Mass, m = 89.4 g

The temperature increases from 23.4°C to 25.5°C. We need to find the specific heat of an unknown metal.

We know that the increase in heat is given by :

[tex]Q=mc\Delta T\\\\c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{58.1}{89.4\times (25.5-23.4)}\\\\c=0.309\ J/g^{\circ} C[/tex]

So, the specific heat of an unknown metal is equal to [tex]0.309\ J/g^{\circ} C[/tex].

D. Al(s) → AB+(aq) + 3e and Au(s) → Au(aq) + e

Answers

Answer:B is right

Explanation: Al loses electrons and is oxidised, Au gains electron. And is reduced

To solve such this we must know the concept of half cell reaction. Therefore, the correct option is option B that is  Al(s) → A1³⁺(aq) + 3e and  Au(aq) + e [tex]\rightarrow[/tex]Au(s)

What is chemical reaction?

Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.

Oxidation is loss of electrons and reduction is gain of electrons. The electron transfer from oxidant to reductant. Al loses electrons and is oxidized, Au gains electron. And is reduced.

Therefore, the correct option is option B that is  Al(s) → A1³⁺(aq) + 3e and Au(aq) + e [tex]\rightarrow[/tex]Au(s)
