Answer: The products of electrolysis are Zn(l) and [tex]Cl_2[/tex] gas

Explanation:

Electrolysis of a subastance is breaking it into its constituents by the action of electrical current.  

In the electrolysis of molten zinc chloride, zinc metal is produced at the cathode which is a negative electrode and chlorine gas produces as the anode which is a positive electrode.

[tex]ZnCl_2(l)\rightarrow Zn^{2+}+2Cl^-[/tex]

At anode : [tex]2Cl^-(l)\rightarrow 2e^-+Cl_2(g)[/tex]

At cathode : [tex]Zn^{2+}(l)+2e^-\rightarrow Zn(l)[/tex]

Answer:

Convergent

Explanation:

I don't know whether this is one of your answers but It is convergent because convergent boundaries are when two plates collide against each other which can create mountains and volcanos.

Explanation:

What would you expect to find?

- The masses of the reactants would be equal to the masses of the product.

Why?

- This is due to the law of conservation of matter which states that matter is neither created nor destroyed in an isolated system but converted from one form to the other.

How is this related to balancing your equations?

- This is why during balancing of equations, we must ensure that the number of atoms in the reactant side must be equal to the number of atoms in the product side.

Answer:

D. Certain blood vessels are blocked by fatty acids

Explanation:

A heart attack occurs when the flow of blood to the heart is blocked. The blockage is most often a buildup of fat, cholesterol and other substances, which form a plaque in the arteries that feed the heart (coronary arteries). Sometimes, a plaque can rupture and form a clot that blocks blood flow.

Answer:

0.01 M

Explanation:

NaOH (sodium hydroxide) is a strong base, so it is completely dissociated into ions in aqueous solution:

NaOH ⇄ Na⁺ + OH⁻

So, we have OH⁻ ions in solution.

From the problem, we have the pH value. The pH is calculated as:

pH = -log [H⁺]

As NaOH is a base, we can also calculate the pOH:

pOH = -log [OH⁻]

Thus. we can use the relation between pH and pOH to calculate the pOH and then use it to calculate [OH⁻]:

pH + pOH = 14 ⇒ pOH = 14 - pH = 14 - 12.05 = 1.95

pOH = -log [OH⁻] ⇒ [OH⁻] = [tex]10^{-pOH}[/tex]= [tex]10^{1.95}[/tex]= 0.0112 M ≅ 0.01 M

Answer:

0.0112

Paraffin oil is used for determination of boiling point and melting point for the following reasons: It has a very high boiling point and so it can be used to maintain high temperatures in the boiling and melting point apparatus without loss of the substance.

Yes, As the gravity/distance increases between two objects, the gravitational pull between them weakens/strengthens.

There is a gravitational force of attraction between every object in the universe. The size of the gravitational force is proportional to the masses of the objects and weakens as the distance between them increases.

Answer:

Option D. 7.56 g of Hg.

Explanation:

The balanced equation for the reaction is given below:

4HgS + 4CaO —> 4Hg + 3CaS + CaSO₄

Next, we shall determine the mass of CaO that reacted and the mass of Hg produced from the balanced equation. This is can be obtained as follow:

Molar mass of CaO = 40 + 16

= 56 g/mol

Mass of CaO from the balanced equation = 4 × 56 = 224 g

Molar mass of Hg = 200.59 g/mol

Mass of Hg from the balanced equation = 4 × 200.59 = 802.36 g

SUMMARY

From the balanced equation above,

224 g of CaO reacted to produce 802.36 g of Hg.

Finally, we shall determine the mass of Hg produced by the reaction of 2.11 g of CaO. This can be obtained as follow:

From the balanced equation above,

224 g of CaO reacted to produce 802.36 g of Hg.

Therefore, 2.11 g of CaO will react to produce = (2.11 × 802.36)/224 = 7.56 g of Hg.

Thus, 7.56 g of Hg were obtained from the reaction.

Answer:

Boiling T° of solution = 135.6°C

Explanation:

Formula for elevation boiling point is:

ΔT = Kb . m . i

ΔT =  Boiling point of solution - Boiling point of pure solvent

Kb = Boiling point elevation constant

m = molality →  moles of solute in 1kg of solvent

i = numbers of ions dissolved

FeCl₃ →  Fe³⁺  +  3Cl⁻

In the dissociation of the ionic salt, we determined 4 moles of ions dissolved.

3 for chlorides and 1 for iron. Then i = 4

m → We convert the mass of solute to moles:

90 g . 1mol / 162.2g = 0.555 moles

650 g of solvent = 0.650 kg of solvent

m = 0.555 mol/0.650kg → 0.85

We replace data at formula

Boiling T° of solution - 129.90°C = 1.67°C . kg/mol  .  0.85 mol/kg . 4

Boiling T° of solution = 1.67°C . kg/mol  .  0.85 mol/kg . 4 + 129.90°C

Boiling T° of solution = 135.6°C

Answer:

0.019 atm / hr

Explanation:

Initial Concentration (Pressure) [A]o = 0.473 atm

Final Concentration (Pressure) [A] = 0.376 atm

Time = 5.6 hours

The breakdown follows first order kinetics.

The integrated rate law for a first order reaction is given as;

ln[A] = ln[A]o - kt

ln(0.376) = ln(0.473) - k (5.6)

ln(0.376) - ln(0.473) = - 5.6 k

5.6 k = 0.23

k = 0.0411 hr⁻¹

The rate of decomposition is given as;

Rate = k [X]

Where [X] represents Concentration (Pressure) = 0.473 atm

Rate = 0.0411 * 0.473 = 0.019 atm / hr

See explanation and image attached

Explanation:

This reaction begins when the pi bond in 2-methylpropene is attacked by a proton. A tertiary carbocation is formed which now may attack a benzene ring in an electrophilic reaction. A tertiary carbocation is very stable.

The electrophilic attack of the tertiary carbocation yields the final product  tert-butylbenzene as shown in the image attached.

Answer:

A carbon dioxide

its how carbon is transferred

Carbon cycle is the process of balancing the amount of carbon in the atmosphere and what is present in plants and animals. In carbon cycle, carbon is transferred in the form of carbon dioxide from animals to plants.

Carbon cycle is a geochemical cyclic process by which the carbon gas is exchanged between the atmosphere and biosphere. Carbon is the main content of all biological materials as well as living.

These events in carbon cycle balance the amount of carbon in atmosphere and biosphere to sustain life. Thus the wasted carbon from animals are recycled back to the atmosphere in the form of carbon dioxide.

We intake oxygen and release carbon dioxide. The released carbon dioxide is uptaken by plants and used for photosynthesis. By the process of photosynthesis, plants are making glucose and energy.

Therefore, In the carbon cycle, carbon is transferred from animals to plants in the form of A. carbon dioxide.

Different visible waves show different colors

In the electromagnetic spectrum, different  visible waves show different colors.

The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

DNA or deoxyribonucleic acid is a hereditary material present in humans as well as all living beings. Almost every cell present in the body has DNA. Most DNA are located inside the cell , that is in the nucleus of the cell. But a small portion of DNA  can be found in the mitochondria of the cell as well.

The information in DNA is stored as a code which is composed of four chemical bases 1) adenine 2)guanine 3) cytosine  4) thymine . The human DNA consists of 3 billion bases . The order of of these bases determine information which is used for building and maintaining an organism.

The DNA bases can pair with each other .Adenine pairs with thymine   and guanine with cytosine to form units which are called as base pairs.Each base apart from other complementary base it also attaches itself to a sugar and a phosphate molecule.
