This reaction was at equilibrium when 0.2 atm of iodine gas was pumped into the container, what happened to the equilibrium and
n200080 [17]

Answer:

Q was < K. Partial pressure of hydrogen decreased, iodine increased

Explanation:

<em>After iodine was added the Q was [Select] K so the reaction shifted toward the Products [Select] ,The partial pressure of hydrogen [Select], Iodine [Select] |,and hydrogen iodide Decreased</em>

Based on the equilibrium:

H2(g) + I2(g) ⇄ 2HI(g)

K of equilibrium is:

K = [HI]² / [H2] [I2]

<em>Where [] are concentrations at equilibrium</em>

And Q is:

Q = [HI]² / [H2] [I2]

<em>Where [] are actual concentrations of the reactants.</em>

<em />

When the reaction is in equilibrium, K=Q.

But as [I2] is increased, Q decreases and Q was < K

The only concentration that increases is [I2], doing partial pressure of hydrogen decreased, iodine increased

IrinaK [193]
1) Multiply the correct answer by 1% => 7.80009 * 1/100 = 0.0780009

2) Calculate minimum and maximum values:

a) Maximum: 7.80009 + 0.0780009 = 7.8780909

b) Minimum: 7.80009 - 0.0780009 = 7.7220891

3) Valid range: [7.7220891, 7.8780909]

4) Conclusion: 7.80, 7.730 and 7.80703 are inside the range and are inside the tolerance, while 7.6363, 7.6 and 7.76 are not.

Select the isotopes from the following?<br> A) 21/10 B) 22/10 C) 23/11 D)23/12
iren [92.7K]

The isotopes of the same element in the given options are 21/10 and 22/10 (option A and B).

<h3>What is an isotope?</h3>

Isotopes are two or more forms of an element where the atoms have the same number of protons, but a different number of neutrons within their nuclei.

The above definition shows that atoms of isotopes will have the same atomic number but a different mass number.

Isotopes of the same elements have different number of neutrons and this causes the difference in mass numbers.

According to this question, 21/10 and 22/10 are isotopes of the same element because they have the same atomic number.

Study the chemical reaction.
viktelen [127]

Answer: The mole ratio between Fe and O_2 is \frac{4Fe}{3O_2}

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The given balanced chemical equation is :

4Fe+3O_2\rightarrow 2Fe_2O_3

Thus 4 moles of iron (Fe) reacts with 3 moles of oxygen gas (O_2) to give 2 moles of ferric oxide (Fe_2O_3)

The mole ratio between Fe and O_2 is \frac{4Fe}{3O_2}
