The quantity of solar energy available to produce electricity is not affected by location on Earth's surface. This statement is true about solar energy.

Solar energy uses the sun's rays to create heat, light, and electricity. It is a renewable energy source. Heat may be employed in industrial activities like manufacturing whereas light can be immediately transformed into energy..

Solar energy may be converted directly into electrical power. A nonmechanical device called a photovoltaic cell is often constructed of silicon alloys. Photons, or solar energy particles, make up sunlight.

Due to the employment of particular grade silicon and silver during production, solar cells have a high cost of production. Solar cells don't have any moving components, so they may be readily installed in distant locations, but once installed, they don't require any care.

Thus, option D is correct.

Explanation:

Answer:

B) by first reversing Reaction 2 and then adding the enthalpy of Reaction 1 and the enthalpy of Reaction 2

Explanation:

C2H2 (g)+2H2 (g)→C2H6 (g)   ΔH=−75 kcal

C2H4 (g)+H2 (g)→C2H6 (g)     ΔH=−33 kcal

C2H2 (g)+H2 (g)→C2H4 (g)     ΔH= ?

First step - Reverse reaction 2.

C2H6 (g)  → C2H4 (g) + H2 (g)    ΔH= 33 kcal

Second step - Add reaction 1 and the reversed reaction 2. This gives us:

C2H2 (g) + 2H2 (g)  +  C2H6 (g) → C2H6 (g) + C2H4 (g) + H2 (g)

Ionic compounds are formed from the interaction between cation ions and anions. A cation of an atom can be described as an electropositive ion and can donate valence electrons. Similarly, anions of an atom are electronegative ions and can accept electrons.

In an ionic compound, there is a complete transfer of electrons in the formation of an ionic bond, therefore, there exists an electrostatic force of attraction between the ions that forms a strong bond.

In a covalent compound, there is the mutual sharing of electrons in the covalent bonds. The shared electrons are hard to give away as nuclei of two atoms together share the electrons and create a bond stronger.

The balloon has a capacity of 0.7 L after being heated to 250°C.

We utilize the Charles' Law equation to determine the system's ultimate volume. According to this rule, the volume of a gas under constant pressure is precisely proportional to its temperature.

Mathematically,

V1/T1 = V2/T2

where,

V1 and T1 are the gas's starting volume and temperature.

V2 and T2 are the gas's ultimate volume and temperature.

We receive:

V1 = 0.4L

T1 = 20.C = (20 + 273)K = 293K

V2=?

T2 = 250.C = (250 + 273)K + 523)K

Using the values in the equation above, we obtain:

0.4/293 = V2/523

V2 = 0.7L.

As a result, the balloon has a capacity of 0.7 L after being heated to 250°C.

The surface temperature of a block of solid carbon dioxide (dry ice) is -78.5 degrees Celsius (-109.8 degrees F). Once it reaches this temperature, carbon dioxide completely bypasses the liquid state and transforms into a gas. One pound of dry ice produces 250 liters of carbon dioxide gas!

Carbon dioxide in the form of dry ice is employed. Sublimation is the process by which CO2 transforms from a solid to a gas without first undergoing a liquid phase, and it takes place at pressures lower than 5.13 atm and temperatures higher than 56.4 °C (216.8 K; 69.5 °F) (the triple point).

An example of a fission reaction is as follows:

²³⁹Pu₉₄ + n¹₀⇒¹⁴⁴Ce₅₈ + ⁹⁴Kr₃₆ + ¹n₀

²⁴¹Am₉₅ + ¹n₀ ⇒ ¹⁴⁴La₅₇ + ⁹⁵Sr₃₈ + ¹n₀

A fission reaction is a type of nuclear reaction in which the nucleus of an atom is split into two or more smaller nuclei, along with the release of a large amount of energy and several neutrons. This process occurs when the nucleus of an atom absorbs a neutron and becomes unstable, causing it to split apart.

Fission reactions can occur naturally, as in the decay of certain radioactive isotopes, or can be induced by bombarding a nucleus with high-energy particles.

Fission is also the process used in nuclear power plants to generate electricity, where the heat produced by the fission reaction is used to produce steam that drives turbines.

An ideal gas is a gas composed of a large number of identical molecules that obey the ideal gas law.

What do you mean by Gas?

Gas is a state of matter made of atoms and molecules that are not bound together, allowing them to move freely and take the shape and volume of their container. It is one of the four fundamental states of matter (the others being solid, liquid, and plasma).

The heat exchanged in a two-step process is given by

q = CpΔT + (P1V1 – P2V2)

where Cp is the specific heat capacity of the gas, ΔT is the change in temperature, P1 and V1 are the initial pressure and volume, and P2 and V2 are the final pressure and volume.

For the two-step process,

q = CpΔT + (2.00 atm x 6.40 L – 2.50 atm x 3.20 L)

For the one-step process,

q = CpΔT + (2.50 atm x 6.40 L – 2.50 atm x 2.56 L)

The difference in q for the two-step process and the one-step process is

q2 – q1 = (2.50 atm x 3.20 L – 2.00 atm x 6.40 L)

q2 – q1 = (7.68 L atm – 12.80 L atm)

q2 – q1 = -5.12 L atm

Since 1 L atm = 101.3 J, the difference in q for the two-step process and the one-step process is

q2 – q1 = -5.12 L atm x 101.3 J/L atm

q2 – q1 = -517.4 J.

Hence, the difference is -517.4 J.

Increasing the amplitude means you are increasing the energy of a wave option -D is correct answer.

The distance between the wave's base and its crest is its amplitude. It represents the furthest the vibrating body has traveled.

As the vibration of the sound particles increases, the amplitude length also grows. The intensity and energy of the sound particle particles increase as a result. The sound is louder as a result of the increased energy.

The energy increases with increasing amplitude. In conclusion, waves carry energy. Their frequency and amplitude are related to the amount of energy they carry. Energy increases with frequency and amplitude, respectively, as they both rise.

Moving down the concentration gradient means that materials move from an area of high concentration of the material to an area of low concentration of the material.

In chemistry, concentration is the amount of a substance in a given space. Another way to describe concentration is the proportion of the solute to a solvent or entire solution. In general, mass/unit volume is used to express concentration. Instead of using volume, concentration can be stated as a mass per unit. Although concentration is typically used to describe chemical solutions, it may be computed for any mixture.

The empirical formula of the compound is MnO2.

The empirical formula of a substance is the simplest whole-number ratio of atoms in a compound. To find the empirical formula of a compound, you first need to determine the number of moles of each element present in the compound.

Given that the percent composition of the compound is 70% Mn and 30% O, we can assume that 100g of the compound contains 70g Mn and 30g O.

To convert mass to moles, we need to know the molar mass of each element. The molar mass of Mn is 54.9380 g/mol, and the molar mass of O is 16.00 g/mol.

So, we have:
