The lithium-iodine battery is used in pacemakers to generate small electrical impulses that trigger the heart to beat according to the following equation. Identify
the species oxidized.
2 Li(s) + I2 (s) → 2 Lil(aq)

Answers

Answer 1

Answer:

The species that oxidizes is lithium, or Li

Explanation:

Since I2 is know to be a halogen, and halogens are oxidizers, iodine is probably not the species being oxidized. So, Li is being oxidized.


Another way to look at the problem is to assign oxidation numbers to all elements on the right and left

The left:
lithium = 0
iodine = 0
Both are 0 since they are in their most stable elemental states

The right:
lithium : +1
Iodine: -1

When something looses an electron and becomes more positive, it is oxidized. Lithium goes from 0 to 1, clearly displaying a rise in oxidization state. So, lithium is being oxidized.

Which atom (magnesium or chlorine) has a higher electronegativity?___________________________(you should also be prepared to answer the question if asked for lower electronegativity)5a. Explain why the atom has a higher electronegativity energy. Include the definition of electronegativity, the trend from the periodic table and the reason the trend exists based subatomic particle

Answers

Answer:

Chlorine has higher electronegativity

Explanations:What is electronegativity of an element?

This is the tendency of an element to attract electron to itself. According to the periodic table, the electronegativity of an element increases from the left to the right across the period and decreases top to bottom down the group.

This trend exists due to the electronic configuration of the elements. Chlorine element has 7 valence electron in its outer shell and as such will easily accept an electron to itself to attain its octet configuration compared to magnesium that looses his two valence electrons to other elements in order to attain octet configuration.

The tendency of chlorine atom to attract electron makes it have a higher electronegativity compared to magnesium.

In this instance, it is safe to think of the size of an atom with the electron and nucleus position.

• The larger atom ( more electons ) the more reactive. the larger the atom will also be further from the nucleus and therefore further from the positively charged nucleus.

• Therefore, in terms of attraction, it will be easier for the valence electrons to leave the atom and form ionic bond /interact with another atom to form covalent bond .

In conclusion, reactivity of an element is related to changes in the electronic structure which is strongly dependent upon the attraction of valence electrons to the nucleus.

What volume,expressed in liters,would 432.8 grams of fluorine occupy?

Answers

ANSWER

The volume of fluorine is 510.52L

STEP-BY-STEP EXPLANATION:

From the question provided, you were given the mass of fluorine to be 432.8 grams.

Given information

Mass of fluorine = 432.8 grams

To find the volume of Fluorine, we need to find the mole of fluorine from the mole formula

[tex]\text{Mole = }\frac{\text{ reacting mass}}{\text{ molar mass}}[/tex]

From the periodic table, the molar mass is 18.99 g/mol

The next thing is to substitute the data into the formula

[tex]\begin{gathered} \text{Mole = }\frac{\text{ 432.8}}{18.99} \\ \text{Mole = }22.79\text{ moles} \end{gathered}[/tex]

Since the mole of fluorine is 22.79 moles, then, we can now find the volume of fluorine.

At STP, 1 mole is equivalent to 22.4L

Let the volume of fluorine be x

[tex]\begin{gathered} 1\text{ mole }\rightarrow\text{ 22.4L} \\ 22.79\text{ moles }\rightarrow\text{ xL} \\ \text{Cross multiply} \\ 1\cdot\text{ x = 22.4 }\cdot\text{ 22.79} \\ x\text{ = 510.52L} \end{gathered}[/tex]

The metal Strontium is symbolized by Sr, and since it is a metal its oxidation number is 0, so no charge.

In this reaction, the Sr will become 2+, so, since Cl is 1-, the proportion is 1 Sr to 2 Cl, so the unbalanced reaction is:

[tex]Sr+HCl\to H_2+SrCl_2[/tex]

To balance it, we need to add a coefficient of 2 on HCl, so we have 2 H on both sides and 2 Cl on both sides.

The Sr is and continue balanced.

So, the balanced reaction is:

[tex]Sr+2HCl\to H_2+SrCl_2[/tex]

As we can see, the left part has Sr alone and H with Cl, while on the right side this changes, H is alone and Sr is with Cl. This means that Cl was displaced from H to Sr, so this is a single displacement reaction.

when 0.56 grams of CuCl2 react with 0.64 grams of Kl, what is the limiting reactant in the production of iodide?

Answers

Answer:

[tex]KI[/tex]

Explanation:

Here, we want to get the limiting reactant

The limiting reactant is the reactant that produces less amount of the product

We start by writing the balanced equation of the reaction:

We have this as:

[tex]2CuCl_2\text{ + 4KI }\rightarrow\text{ Cu}_2I_2\text{ + I}_2\text{ + 4KCl}[/tex]

The iodide here is the copper (i) iodide

From the question, we have 0.56 g of copper (ii) chloride

We need to get the number of moles of it that reacted

We can get that by dividing the mass by the molar mass of copper (ii) chloride

The molar mass of copper (ii) chloride is 134.45 g

Thus, we have the number of moles as:

[tex]\frac{0.56}{134.45}\text{ = 0.004165 mol}[/tex]

From the equation of reaction, 2 moles of copper ii chloride produced 1 mole of the iodide

Thus, the number of moles of the iodide produced by the actual reacting mass would be:

[tex]\frac{0.004165}{2}\text{ = 0.0020825 mol}[/tex]

Now, let us get the number of moles produced by Potassium iodide

We can get this by dividing the mass by the molar mass of potassium iodide

The molar mass of potassium iodide is 166 g/mol

Thus, we have the number of moles as:

[tex]\frac{0.64}{166}\text{ = 0.00386}[/tex]

From the equation of reaction, 4 moles of KI produced 1 mole of the iodide

Thus:

[tex]\begin{gathered} 0.00386\text{ mol will produce:} \\ \frac{0.00386}{4}\text{ = 0.000965} \end{gathered}[/tex]

From what we can see, potassium iodide would give less mass of the copper (i) iodide

This makes potassium iodide the limiting reactant

How many grams of KClO3 are needed to produce 6.75 Liters of O2 gas measured at 1.3 atm pressure and 298 K?

Answers

Answer

Procedure

To solve this question consider the following chemical reaction:

2KClO₃→2KCl+3O₂

Then we will use the ideal gas formula to determine the number of moles present in 6.75 L of oxygen gas.

Data:

V=6.75 L

T= 298 °K

P= 1.3 atm

R= 0.08206 L⋅atm⋅°K⁻¹⋅mol⁻¹

Equation

PV=nRT

Solve for n to get the moles

[tex]n=\frac{PV}{RT}=\frac{1.3\text{ atm }6.75\text{ L mol }\degree\text{K}}{0.08206\text{ L.atm 298}\degree\text{K}}=0.3588\text{ mol O}_2[/tex]

Use the stoichiometry of the reaction to convert from moles of oxygen to moles of KClO₃.

[tex]0.3588\text{ mol O}_2\frac{2\text{ mol KClO}_3}{3\text{ mol O}_2}=0.2392\text{ mol KClO}_3[/tex]

Finally, convert from moles to grams

. If you do 4 J of work by pulling on a rubber band, the rubber band releases 12 J of heat (stretching of rubber band causes friction of molecules which releases heat). What is the change in internal energy of the system (the rubber band)?

Answers

The change in internal energy of the system is found to be -8joules.

We know that, work done W by the system is taken as negative. Work done on the system is taken as positive.

Heat absorbed Q by the system is taken as positive and heat released by the system is taken as negative.

It is given,

W = +4J (Work done on the system)

Q = -12j (Head released by the system)

Now, we calculate change in Internal energy ΔE of the system by using first Law of thermodynamics,

It says, total change in internal energy is equal to the sum of work done and heat absorbed,

So, we can write,

ΔΕ = Q + w

Putting the values,

ΔΕ = −12+ 4

ΔΕ = -8J

Hence, change in internal energy of the system is -8joules.

There are protons, neutrons, and electrons, three types of subatomic particles. Protons and electrons, two of the subatomic particles, each have an electrical charge of one or the other. On the other hand, neutrons lack a charge.

What do you mean by electric charge?

The fundamental feature of matter known as electric charge, which is carried by some elementary particles, determines how the particles are affected by an electric or magnetic field.

Protons are positively charged particles that are found inside the atom's nucleus. Neutrons are found inside the atom's nucleus and are neutral particles.

Electrons are negatively charged particles that surround the nucleus by unclear paths.
