Answer:

[tex][I_2]=[H_2]=0.0157M[/tex]

[tex][HI]=0.124M[/tex]

Explanation:

Hello!

In this case, for the undergoing chemical reaction, we can write the equilibrium expression as shown below:

[tex]Kc=\frac{[HI]^2}{[I_2][H_2]}[/tex]

However, since the reactions starts with 0.155 M hydrogen iodide, we need to invert the reaction as well as the equilibrium expression:

[tex]2HI\rightarrow I_2+H_2[/tex]

[tex]\frac{1}{Kc}=0.0163 =\frac{[I_2][H_2]}{[HI]^2}[/tex]

And each concentration at equilibrium in terms of the reaction extent is:

[tex][I_2]=[H_2]=x[/tex]

[tex][HI]=0.155-2x[/tex]

Thus, plugging in the new expression we write:

[tex]0.0163 =\frac{x*x}{(0.155-2x)^2}[/tex]

Which has the following valid solution for [tex]x[/tex]:

[tex]x=0.0157M[/tex]

Because the other solution is negative. Therefore, the concentration of hydrogen, iodine and hydrogen iodide at equilibrium turns out:

[tex][I_2]=[H_2]=0.0157M[/tex]

[tex][HI]=0.155-2(0.0157)=0.124M[/tex]

Best regards!

At the equilibrium, the concentration of hydrogen and iodine has been 0.0157 M each, and the concentration of HI will be 0.124 M.

The initial concentration of the reactant has been 0.155 M. From the balanced chemical equation, the ICE table will be:

         HI          [tex]\rm H_2[/tex]          [tex]\rm I_2[/tex]

I      0.155        0           0

C       -2x         x           x

E  0.155 - 2x    x          x

The value of the equilibrium constant can be given by the ratio of the concentration of products to the reactant.

The equilibrium constant for the reaction will be:

[tex]\rm k_c\;=\;\dfrac{[H_2]\;[I_2]}{[HI]^2}[/tex]

The given constant value has been for the opposite reaction. Thus the constant for the required reaction has been :

[tex]\rm \dfrac{1}{given\;k_c} \;=\;\dfrac{[H_2]\;[I_2]}{[HI]^2}[/tex]

[tex]\rm \dfrac{1}{61.5}[/tex] = [tex]\rm \dfrac{(x)\;(x)}{(0.155-2x)^2}[/tex]

0.0162 = [tex]\rm \dfrac{x^2}{(0.155-2x)^2}[/tex]

By simplyfying the equation,

x = 0.0157 M

At the equilibrium, the concentration of hydrogen and iodine has been 0.0157 M each.

The concentration of HI will be:

HI = 0.155 - 2x

HI = 0.155 - 2(0.0157)

HI = 0.124 M.

Answer:

Chromium, calcium, and osmium

Explanation:

These elements are metals, considering this, these elements electron shells(orbitals) are further away from the nucleus, with this, their attractions are not as strong as non-metals, so some of their electrons are able to move freely.

When you accumulate many atoms, these metals can form a "sea of electrons"  because they all have loose electrons interacting with each other. This allows easy conduction of heat and electricity.

Answer:

Chromium

Calcium

Osmium

Explanation:

The elements likely conduct electricity well are chromium, calcium and osmium. As these are metals and are observed to be good conductors of heat and electricity. They have extra electrons to donate and hence flow of electrons cause them to be a good conductor of electricity. Rest iodine is a non-metals which is not good conductors of electricity. Carbon is not itself a good conductor but one of its allotrope which is graphite is a good conductor of electricity.

The correct answer is - Orange light reflected from the t-shirt enters human eyes.

Explanation:

Human eyes and brain are altogether able to detect the color of the object by translating the light which is reflected by the object and transmitted by the light receptors in the eyes ad brain translate light to color.

The objects are able to absorb some colors and reflect others on the basis of their wavelength, The reflected colors are detected by our eyes and brain and objects appear to be a particular color. like here, the orange color is reflected by the t-shirt and enters in human eyes.

Answer:

pH = 6.5

Explanation:

Given data:

pH of substance = ?

[OH⁻] concentration = 3.2×10⁻⁸

Solution:

pOH = -log[OH⁻]

pOH = -log[3.2×10⁻⁸]

pOH = 7.5

we know that,

pH + pOH = 14

pH = 14- pOH

pH = 14 - 7.5

pH = 6.5

Answer:

Average atomic mass  = 6.93 amu.

Explanation:

Given data:

Percent abundance of lithium -6 = 7%

Percent abundance of lithium - 7 = 93%

Average atomic mass of Li = ?

Solution:

Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass)  / 100

Average atomic mass  = (7×6)+(93×7) /100

Average atomic mass =  42+ 651 / 100

Average atomic mass  = 693/ 100

Average atomic mass  = 6.93 amu.

Answer:

53.5 N?

Explanation:

34.77 Joules of work is done on the backpack.

Work-done on any body can be calculated as:

W = F × x, where

F = force

x = displacement or distance

In the question, given that

Force to lift a backpack = 53.5 N

And distance = 0.65 m

Now work-done is calculated as:

W = 53.5 × 0.65 = 34.77 Joules

Hence, 34.77J of work is done.

Answer and Explanation:

A) Unconditioned Stimulus- The onion

B) Unconditional Response- Crying

C) Conditioned Stimulus- Chiming clock

D) Conditioned Response- Crying

In the above scenario( an example of classical conditioning), Elmer has been conditioned by the continuous iterations of having to cook everyday by 5pm. He cooks with onions by 5pm around the same time his uncle's clock chimes five times. He cries/has teary eyes(unconditioned response) because of the response to the onions(unconditioned stimulus) around the same time the clock chimes five times thereby conditioning his response so that even when the onions isn't there/he isn't even cooking, he tears up to the clock chimes around 5pm. The clock is therefore a conditioned stimulus and there is a conditioned response of crying.

The unconditioned response to an unconditioned stimulus happens naturally(an instinct) because it is a biological response to the onions, not conditioned.
