How do renewable and nonrenewable resources differ?

Answer:

Their mass stays the same but their weight changes.

Explanation:

The gravitational force of celestial bodies is determined by their mass and size. The moon has less mass than the Earth and can't pull object towards itself as well as the Earth. Thus, mass remains the same and you'd weigh less.

Initially, the Final speed of a molecule of an ideal gas is 327 m/s. the pressure and volume of this gas are kept constant, while the number of molecules is doubled.

The square root of the mean of the squares of the velocity of individual gas molecules is known as the root mean square velocity (RMS value).

T = Kelvin-degree temperature.

The arithmetic mean of the velocities of various gas molecules at a specific temperature is known as average velocity. Actually, root mean square speed, not velocity, is what the RMS calculation tells you.

Considering that velocity is a vector quantity with both magnitude and direction, this makes sense.

The behavior pf the molecule is given by -

PV = 2/3 N (1/2mv²)

We may write p1v1 = p2v2,

where the subscript 1 denotes the beginning condition

subscript 2 denotes the conditions following the number of molecules being doubled, because the pressure and volume of the gas are held constant while the number of molecules is doubled. Thus,

⇒ 2/3 [N1 (1/2 mv1²)] = 2/3 [N2 (1/2 mv2²)]

⇒ N1 v1² = N2 v2²

⇒ v2 = v1 √(N1/N2)

⇒ v2 = 463 √(N1 / 2N1)

⇒ v2 = 463 / √2

⇒ v2 = 327m/s

Thus, the final speed of the molecules is 327 m/s.

The specific volume of diatomic nitrogen is 13.37 ft³/lb by mass and 0.0265 m³/mol by mole.

1) m(N2) = 1 lb; mass of diatomic nitrogen

V(N2) = 100 gal = 13.37 ft³; volume of diatomic nitrogen

The standard unit for specific volume is cubic meters per kilogram or cubic feet per pound (ft³/lb).

ν = V / m; formula used to calculate specific volume (ν) by mass

ν = 13.37 ft³ / 1 lb

ν = 13.37 ft³/lb; specific volume by mass

2) M(N2) = 28 g/mol = 0.070 lb/mol; molar mass of diatomic nitrogen

n(N2) = 1 lb / 0.070 lb/mol

n(N2) = 14.29 mol; amount of diatomic nitrogen

ν = V / n; formula used to calculate specific volume (ν) by mole

ν = 13.37 ft³ / 14.29 mol

ν = 0.936 ft³/mol = 0.0265 m³/mol; specific volume (ν) by mole

The molar volume has the SI unit of cubic metres per mole (m³/mol)

The temperature while the water is in the process of freezing it is observed that is solidifies .

What is the process of freezing?

The process through which a substance transforms from a liquid to a solid is known as freezing.

When a liquid's molecules slow down enough to attract one another into permanent positions as a solid, this process is known as freezing.

When water freezes, energy is emitted into the environment, which leads energy to be lost and causes the environment to "cool down".

Since it is not thought to exist, the term "cooling" is not well understood in chemical research and would instead be substituted by the phrase "absence or loss of heat."

When a body's temperature drops, it is said to be cooling. If the temperature drops further, as it would with water, it would ultimately approach the freezing point, which for water is 0 degrees Celsius.

As a result, when cooling passes this thermal barrier, the water "freezes." The freezing point of pure water is 0 degrees Celsius.

Water in a 150 ml container volume with a diameter of 12 cm evaporates faster and therefore has a greater vapour pressure than a container with a volume 75 ml and a diameter of 5.5 cm, because the diameter of 150 ml container is more and more space is exposed, so it evaporates more quickly in lesser time.

The vapour pressure is due to escaping tendency of water molecule from surface of liquid. Vapour pressure is dependent on the number of molecules on the surface of liquid.

If number molecules on surface of molecules is greater, greater would be the vapour pressure.

Since, 150 mL container is with 12 cm diameter, its surface area is larger and it has more number of water molecules on the surface. So, it has greater vapour pressure than the 75 ml container and the water also evaporates faster due to large surface area and more exposure.

The United States uses many different energy sources and technologies to generate electricity. The sources and technologies have changed over time, and some are used more than others.

The three major categories of energy for electricity generation are fossil fuels (coal, natural gas, and petroleum), nuclear energy, and renewable energy sources. Most electricity is generated with steam turbines using fossil fuels, nuclear, biomass, geothermal, and solar thermal energy. Other major electricity generation technologies include gas turbines, hydro turbines, wind turbines, and solar photovoltaics.

Natural gas was the largest source—about 38%—of U.S. electricity generation in 2021. Natural gas is used in steam turbines and gas turbines to generate electricity.

Coal was the second-largest energy source for U.S. electricity generation in 2021—about 22%. Nearly all coal-fired power plants use steam turbines. A few coal-fired power plants convert coal to gas for use in a gas turbine to generate electricity.

Petroleum was the source of less than 1% of U.S. electricity generation in 2021. Residual fuel oil and petroleum coke are used in steam turbines. Distillate—or diesel—fuel oil is used in diesel-engine generators. Residual fuel oil and distillates can also be burned in gas turbines.

The molality of the solution is 3.6 molal

The boiling point is the temperature at which the pressure of the system is equal to the atmospheric pressure. Now we know that freezing point depression is one of the colligative properties.

We have that;

ΔT = K m i

ΔT = Freezing point depression

m = molality of the solution

i = Van't Hoff factor

i =1 because the solute is molecular

ΔT = 5.12 oC/molal * m * 1

We can get ΔT from; Freezing point of pure solvent - Freezing point of solution

=  5.49 °c - ( -13.0 °c) = 18.49°c

m = ΔT /k * 1

m = 18.49°c/5.12 oC/molal

In competitive inhibition, the inhibitor (I) firmly be like the actual substrate (S), and is considered as a substrate analogue. The inhibitor takes part with substrate and cohere at the active site of the enzyme but does not go any catalysis. As long as the competitive inhibitor hold on to the active site, the enzyme is not present for the substrate to cohere.

Where:

Information about the problem:

Applying the density formula, we get:

ρ = m/v

ρ = 38.20 g/ 3.37 cm3

ρ(g/cm3) = 11.34 g/cm3

Converting the density from (g/cm3) to (kg/m3), we get:

11.34 g/cm3 * (1 kg/1000g) * (1000000 cm3/1 m3) = 11,340 Kg/ m3

A buffer solution is composed of 8.50 mol of acid and 2.25 mol of the conjugate base.

What is pH of a solution?

The concentration of hydrogen (H+) ions in a solution, which is a measurement of acidity, is known as the pH of that solution. Acidic solutions have a pH under 7. The same holds true for solutions that have a pH higher than 7.

A buffer solution is one that prevents the pH of a solution from changing when a little amount of a strong acid or basic is added.

Given,

pKa of acid = 4.20

[acid] = 8.50

[base] = 2.25

pH of buffer = pKa + log [base]/[acid]

= 4.20 + log[2.25/8.50]

=3.622

In the given redox reaction, the reducing agent is Cd (s).

When a chemical species "donates" an electron to an electron receptor, it is referred to as a reducing agent in chemistry (also referred to as a reductant, electron donor or reducer).

A reducing agent, which is often in one of its lesser oxidation states, serves as the electron donor. The loss of one electron in the redox reaction results in the oxidation of a reducing agent.

At the anode, oxidation reaction occurs:

[tex]Cd (s) \rightarrow Cd^2^+ (aq) + 2e^-[/tex]

At the cathode, reduction reaction occurs:

[tex]2Li^+ (aq) + 2e^- \rightarrow 2Li (s)[/tex]

The overall redox reaction is:

[tex]Cd (s) + 2Li^+ (aq) \rightarrow Cd^2^+ (aq) + 2Li (s)[/tex]
