The names of the cation in each of the following compounds CaO, Na2SO4, KClO4, Fe (NO3) 2, Cr (OH) 3 are as the cation in CaO is Ca2+, in Na2SO4 it is Na+, in KClO4 it is K+, in Fe(NO3)2 it is Fe2+, and in Cr(OH)3 it is Cr3+.

In a chemical compound, cations are positively charged ions that are formed by the loss of one or more electrons from an atom.

The cation is named after the name of the element from which it is derived, followed by the word "ion". For example, the cation in CaO is Ca2+, which is derived from the element calcium.

So, the name of the cation in CaO is "calcium ion".

Similarly, the cation in Na2SO4 is Na+, which is derived from the element sodium. So, the name of the cation in Na2SO4 is "sodium ion".

The names of the cations in the remaining compounds can be determined in the same way.

The cations in these compounds are Calcium (Ca), Sodium (Na), Potassium (K), Iron(II) (Fe), and Chromium(III) (Cr), respectively.

While geothermal energy is energy that comes from heat contained in the bowels of the earth and is generally associated with the presence of volcanoes. Technically, water that comes from, among other things, rain will seep into the rock beneath the ground until it reaches the reservoir rock.

Geothermal electricity generation is done by drilling the ground in areas that have geothermal potential to create hot gas holes which will be used to heat the boiler so that the steam can drive a steam turbine connected to a generator. For geothermal energy that has high pressure, it can directly rotate the generator turbine, after the steam that comes out is cleaned first.

Ionic compounds are formed from ionic bonds which occur when there is electron transfer, while covalent compounds share electrons. Hence, the answer is true.

Covalent compounds are compounds formed by covalent bonds. Atoms form compounds to achieve a stable electronic configuration. Covalent compounds do this by sharing their electrons. Covalent bonds are weaker than ionic compounds and mostly form gases.

Ionic compounds achieve the stable electronic configuration of noble gases by gaining or giving away their electrons. When this happens, the atoms get attracted to each other by electrostatic forces. Atoms that give away their electrons become positively charged cations and atoms that receive electrons become negatively charged anions.

Therefore, the major difference between ionic compounds and covalent compounds is that covalent compounds share electrons and ionic compounds transfer electrons.

The compounds that are formed can be seen in the equation;

BaCl2 + K2SO4 → BaSO4 + 2KCl

When barium chloride (BaCl2) and potassium sulfate (K2SO4) are mixed in an aqueous solution, a double displacement reaction occurs, resulting in the formation of barium sulfate (BaSO4) and potassium chloride (KCl).

The balanced chemical equation for the reaction is:

BaCl2 + K2SO4 → BaSO4 + 2KCl

In this reaction, the barium ion (Ba2+) from the barium chloride reacts with the sulfate ion (SO42-) from the potassium sulfate to form insoluble barium sulfate (BaSO4), which precipitates out of the solution. At the same time, the potassium ion (K+) from the potassium sulfate reacts with the chloride ion (Cl-) from the barium chloride to form soluble potassium chloride (KCl), which remains in solution.

Answer: Option (b) is the correct answer.

Explanation:

It is known that,

                   pH + pOH = 14

So, pOH = 14 - pH

As the given pH is 9.3. Hence, pOH for the given solution will be calculated as follows.

          pOH = 14 - 9.3

                   = 4.7

Therefore, pOH of the given solution is 4.7.

The volume of steam that could be produced at STP if 12.8 g of oxygen reacts with excess hydrogen is 17.92 L

We'll begin by obtaining the mole of steam produced. This can be obtained as follow:

2H₂ + O₂ -> 2H₂O

From the balanced equation above,

1 mole O₂ reacted to produce 2 moles of steam, H₂O

Therefore,

0.4 mole O₂ will react to produce = 0.4 × 2 = 0.8 mole of steam, H₂O

Finally, we shall determin the volume as follow:

At standard temperature and pressure (STP),

1 mole of H₂O = 22.4 L

Therefore,

0.8 moles of H₂O = (0.8 mole × 22.4 L) / 1 mole

0.8 moles of H₂O = 17.92 L

Thus, we can conclude that the volume produced is 17.92 L

c) Condensation: One example of condensation that we encounter regularly is when water droplets form on the surface of a cold drink on a hot day.

d) Evaporation: Evaporation is the process by which a liquid transforms into a gas or vapor.

e) Sublimation: Sublimation refers to the transformation of a substance directly from a solid to a gas without passing through the liquid state.

a) Melting:  Butter is a solid at room temperature, but when heat is applied, it melts into a liquid. This change is a result of the increase in temperature, which provides enough energy to overcome the intermolecular forces holding the butter molecules together.

b) Freezing:Eventually, the temperature reaches the freezing point of water (0°C or 32°F), at which the water molecules slow down and arrange themselves into a regular, crystalline structure. This transformation from a liquid to a solid state is accompanied by the release of heat energy.

c) Condensation: As the temperature decreases, the air's capacity to hold moisture decreases, causing the water vapor in the air to condense into liquid water droplets. This process occurs due to the transfer of heat energy from the warm air to the cold surface, leading to the saturation of the air and the conversion of water vapor into liquid form.

d) Evaporation:  As the sun's heat energy is absorbed by the water molecules on the clothes' surface, their kinetic energy increases, causing them to break free from the liquid phase and escape into the surrounding air as water vapor. This process occurs because the molecules at the liquid surface with sufficient energy can overcome the attractive forces within the liquid and enter the gas phase.

e) Sublimation: Sublimation refers to the transformation of a substance directly from a solid to a gas without passing through the liquid state. An example of sublimation is the process of dry ice (solid carbon dioxide) converting into carbon dioxide gas.

Answer: a. 1.11 atm, 0.43 mol

Explanation:

The presented statement states that 52.5 lbs. of salt had been consumed after 30 minutes.

Salts come in a variety of forms, such as a double salt, corrosive salt, or basic salt. A salt that forms when a potent acid and a feeble base interact is referred to as a "acidic salt."

There seem to be initially 100 gal with in tank. The amount of salt is 60 lbs. The tank has a salt content of 60/100, or 0.6 pounds per gal.

One pound per gallon of water is coming in.

Because the combination is continually varying, the concentration of the water that comes out is uncertain.

Each minute, the tank is dropping 1 gal. (3-2=1)

Utilize this information to configure three functions for volume, saturation, and salt content: V(t), S(t), and C(t).

V (t) = 100 - t

s (t) = 60 plus 2t - 3t * C (t)

C (t) = s(t)/V(t) = 60 + 2t - 3t * C(t)/ 100 - t

Solve for C with a little mathematics (t)

C (t) = 60 + 2t / 100 + 2t

Now, we are aware of the tank's salt content at all times.

Evaluate at t = 30

C (30) = 60 + 2(30)/100 - 2(30) = 120/160 = 3/4

s(30) = 60 + 2(30) - 3(30)(3/4) = 120 - 90(3/4) = 52.5

Consequently, 52.5 lbs of salt had been consumed within 30 minutes.
