<h2>Answer:</h2>

Oxidized specie: I2 (iodine)

Reduced specie: 2 Cl- (Chlorine)

<h3>Explanation:</h3>

Reaction: 2 I- + CI2 → 2CI- +I2

According to the definitions of oxidation and reduction with respect to electron transfer:

Reduced Species are species that absorbs or add electron and gain negative charge or neutral.

Oxidized species are species in reactions that release electrons to gain a positive charge or neutral.

Hence chlorine in this reaction absorbs electron to become Cl-.
And iodine release electrons to become neutral.
So chlorine is reduced while iodine is oxidized.

Answer is: I⁻ is oxidized and Cl₂ is reduced.

Balanced oxidoreduction reaction: 2I⁻ + Cl₂ → 2Cl⁻ + I₂.

Iodine lost electrons and change oxidation number from -1 (iodine anionI⁻) to oxidation number 0 (iodine molecule I₂).

Chlorine gain electrons and change oxidation number from 0 (molecule of chlorine Cl₂) to oxidation number -1 (chlorine anion Cl⁻).

Yuki888 [10]

Answer: The new pressure is 7.1 atm

Explanation:

To calculate the final pressure of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$

where,

$P_1\text{ and }T_1$ are the initial pressure and temperature of the gas.

$P_2\text{ and }T_2$ are the final pressure and temperature of the gas.

We are given:

$P_1=6.5atm\\T_1=22^0C=(22+273)K=295K\\P_2=?\\T_2=50^0C=(50+273)K=323K$

Putting values in above equation, we get:

$\frac{6.5}{295}=\frac{P_2}{323}\\\\P_2=7.1$

Hence, the new pressure is 7.1 atm

Which of the following compounds would you expect to be the most reactive?

9966 [12]

The compound that would be most reactive is Ethyne (answer A)

<u><em> explanation</em></u>

Ethyne is the most unsaturated among the four compounds ( <em> it has a triple bond between the two carbon atoms) .</em>

The triple bond in ethyne is made up of 1 sigma bond and 2π bond.

<em>The 2π bond are weaker and can easily break which make Ethyne more reactive than Ethene, methane and Ethane.</em>

Aleks04 [339]

Answer:

1.2x10⁻⁵M = Concentration of the product released

Explanation:

Lambert-Beer's law states the absorbance of a solution is directly proportional to its concentration. The equation is:

A = E*b*C

<em>Where A is the absotbance of the solution: 0.216</em>

<em>E is the extinction coefficient = 18000M⁻¹cm⁻¹</em>

<em>b is patelength = 1cm</em>

<em>C is concentration of the solution</em>

<em />

Replacing:

0.216 = 18000M⁻¹cm⁻¹*1cm*C

<h3>1.2x10⁻⁵M = Concentration of the product released</h3>

Which solution has the lowest pH? A. 1.0 M HNO2 B. 1.0 M CH3COOH C. 1.0 M HCOOH D. 1.0 M HNO3 E. 1.0 M HPO4–

denpristay [2]

The parameter pH is a measure of the substance's acidity or basicity. It is quantitatively equal to the negative logarithm of the concentration of H+ ions. So, the lower the pH, the more acidic the substance, Otherwise, the higher the pH the more basic the substance. The pH range runs from 1 to 14, with 7 being neutral.

So, if we are asked to distinguish which of those have the lowest pH, we have to know the moles of H+ ions. Since all of them have a concentration of 0.1 M, concentration is not a factor. Thus, we just have to identify the strongest acid among the list. That is easy to answer because you only have to remember 7 strong acid occurring in nature: HCl, H₂SO₄, HNO₃, HClO₄, HClO₃, HBr, and HI. Since only HNO₃ is included in the list among the choices, the answer would be letter D.

Identify the tectonic plate boundaries.

Andreyy89

Divergent boundaries and convergent boundaries are the opposite processes that occurs in the tectonic plates.

<h3>Difference between Divergent and convergent boundaries </h3>

Divergent boundaries are the regions where new crust is formed when the plates pull away from each other while on the other hand, Convergent boundaries are the regions where crust is destroyed when one plate dives over another.

So we can conclude that Divergent boundaries and convergent boundaries are the opposite processes that occurs in the tectonic plates.
