Answer:

4202.1 K

Explanation:

From;

PV=nRT

P= pressure of the gas = 18.5 bar

V = volume of the gas = 115L

n= number of moles of the gas =  6.1 mole

T= temperature of the gas = ?

R = gas constant = 0.083 L⋅bar⋅K−1⋅mol−1

T = PV/nR

T = 18.5 * 115/6.1 * 0.083

T = 2127.5/0.5063

T= 4202.1 K

Answer:

Rocks get older as we go away from the Mid Atlantic Ridge  towards the continents

Explanation:

As the plates move away from each other, new ocean lithosphere is created at the ridge. This also widens the ocean basin and leads to sea floor spreading.

The rock of the ocean floor are symmetrically aligned and they get become older as they move away from the crest of the ridge.

Thus, rocks get older as we go away from the Mid Atlantic Ridge  towards the continents

Answer:

2/3, or .66

Explanation:

The decrease in boiling temperature in K is 3.1 K, in °F is approximately 5.58 °F, and in °R is approximately 464.58 °R for each 1000 m rise in altitude.

To convert the decrease in boiling temperature from Celsius (°C) to Kelvin (K), Fahrenheit (°F), and Rankine (°R), we can use the following conversion formulas:

K = °C + 273.15

°F = (°C × 9/5) + 32

°R = °F + 459.67

Given that the decrease in boiling temperature is approximately 3.1 °C for each 1000 m rise in altitude, we can calculate the corresponding values:

Decrease in boiling temperature in K:

ΔT(K) = 3.1 °C

ΔT(K) = 3.1 K (since 1 K = 1 °C)

Decrease in boiling temperature in °F:

ΔT(°F) = (3.1 °C × 9/5) + 32

ΔT(°F) = 5.58 °F

Decrease in boiling temperature in °R:

ΔT(°R) = ΔT(°F) + 459.67

ΔT(°R) = 464.58 °R

Answer:

  18.87 g

Explanation:

  80.1% of 23.56 g = 18.87 g is the mass of the silver

Answer: 140

Explanation:

Given the following :

Mass of metal = 18g = 0.018kg

Mass of water (calorimeter) = 21g = 0.021kg

Initial temperature of metal = 273 + 96 = 369k

Initial temperature of water = 273 + 24 = 297k

Final temperature inside calorimeter = 273 + 26 = 299k

Temperature change of metal = 299 - 369= -70k

Temperature change of water = 299 - 297 = 2k

H = mc ΔT

m = mass

c = specific heat capacity

ΔT = change in temperature

Heat lost by metal = heat gained by water

mc ΔT = mc ΔT

Specific heat capacity of water = 4200

18 * C * ( 299 - 369 ) = 21 * 4.2 * ( 299 - 297)

0.018 × C × -70 = 0.021 × 4.2 × 2

- 1.26 × C = 0.1764

C = 176.4/1.26

C = 140

The sum of oxidation numbers of the three Si atoms in k-feldspars (KAlSi3O8) is +12

The amount of electrons any atom or ion however has gained or lost in comparison to a neutral atom is known as the oxidation number / state of the atom or ion.

k-feldspars, molecular formulae KAlSi3O8

We know that -

Oxidation state of oxygen = -2

Oxidation state of Potassium = +1

Oxidation state of aluminum = +3

8 oxygens, each of them -2, = -16

1 potassium, +1

1 aluminum, +3

1 + 3 - 16 = -12

So the three silicon atoms need to make up +12 for the compound to be neutral.

12 / 3 = +4, so each silicon is +4.

Answer: D convection currents

Explanation:

The seafloor spreading is a phenomena that occurs due to liberation of heat from the convection currents generated in the mantle. It makes the earth crust more plastic and less dense. This happens at divergent plate boundaries. As the plates move apart, the less denser material rises. It leads to the formation of mountain and crust cracks.

When the volume of a gas is changed from 3.75 L to 6.52 L, the temperature will change from 100. 0 K to 173.86 K.

Temperature of the given gas will be calculated by rearranging the ideal gas equation as:

V₁/T₁ = V₂/T₂, where

V₁ = initial volume of gas = 3.75L

T₁ = initial temperature of gas = 100K

V₂ = final volume of gas = 6.52L

T₂ = final temperature of gas = to find?

Putting all these values on the above equation and calculate for the value of T₂ as:

T₂ = (6.52 × 100) / 3.75 = 173.86 K

Hence, 173.86 K is the required temperature.

Answer:

The materials are opaque or crystalline from a client to the orientation and type of union between their atoms, forming two types of structures.

These two structures can be crystalline or amorphous.

In the case of being crystalline, these unions do not allow light to pass through the medium of the object or body of said compound, making it totally refract and giving the appearance of OPAQUE.

On the other hand, in those compounds that we call amorphous, the atoms are located in a different way that makes light pass through them, without absorbing or identifying any light beam, so they look transparent.

3C⁻⁻ on reaction with HI gives I⁻⁻⁻ as the main products and not H⁻ and C₂H₅I.

When 3C⁻⁻ is reacted with HI, the reaction product obtained is I⁻⁻⁻ as the main product. The C₂H₅I and H⁻ are not produced in significant quantities and cannot be considered the main product.The 3C⁻⁻ compound reacts with HI in the presence of a solvent to produce hydrogen gas, H⁻, C₂H₅I, and I⁻⁻⁻. The primary product obtained is I⁻⁻⁻ because it is stable and has a higher energy than C₂H₅I and H⁻.However, the reaction can be controlled to obtain C₂H₅I and H⁻ as the primary products by changing the reaction conditions. The reaction must be carried out in anhydrous conditions and at a low temperature so that the reaction proceeds in the desired direction.

Among the given quantities, the greatest mass of chlorine is represented by one molecule of chlorine Cl₂ that is equal to 71 grams.

A molecule of an element is formed by the combination of two atoms of that element. One mole of an element is the amount containing 6.022 × 10²³ atoms. This s number is called Avogadro number.

The mass of one mole of an element is called its atomic mass. Cl is 17th element. Atomic mass of Cl = 35.5 g

35.5 g of Cl is called one mole of Cl containing Avogadro number of atoms.

One molecule of Cl is represented as Cl₂ with the mass = 35.5 × 2 = 71 g.

This is the molecular mass of Cl.

One gram of Cl is small amount and mass of one atom of Cl is even smaller. Thus, one molecules of Cl represents the greater mass here. Hence, option D is correct.

Explanation:

To calculate the concentration of the iron sample by using a spectrophotometric method, it is necessary to dilute the sample. The volume to which the sample should be diluted is a crucial question in achieving the most accurate result.

The process involves diluting the sample, and the concentration must be calculated to determine the precise result of the dilution. This question can be answered by calculating the uncertainty and identifying the value of the uncertainty. The value with the lowest uncertainty will be the best value to choose. The volume with the lowest uncertainty will be the ideal volume to dilute the 5 ml aliquot of the iron sample to achieve a result with the minimum level of uncertainty.
To determine the optimal volume for dilution, the uncertainty should be calculated.
This can be done by using the equation for propagation of uncertainty, which states that the uncertainty of the result is equal to the square root of the sum of the squares of the uncertainties of the individual components. When calculating the uncertainty of the diluted sample, the uncertainty of the initial sample and the uncertainty of the diluent must be considered. The uncertainty of the initial sample can be calculated using the calibration curve. As the expected iron content is 40-60%, the concentration of the sample is expected to be 8-12 ppm. The uncertainty of the calibration curve is given by the standard deviation of the calibration standards.
The diluent has a negligible uncertainty. The uncertainty of the diluted sample will be lower if a larger volume is used for dilution because the relative contribution of the uncertainty of the initial sample will decrease. However, the uncertainty of the measurement will increase if the sample is diluted too much because the concentration of the analyte will be too low to be detected accurately. A 100 mL volume is a good choice because it balances the need for sufficient dilution to reduce the uncertainty of the initial sample with the need for sufficient concentration to allow for accurate detection of the analyte.

The volume of the sample that should be diluted is 5 ml. The minimum level of uncertainty is obtained at a dilution of 100 ml. When the volume of the diluent is greater than 100 ml, the uncertainty of the measurement increases, and when the volume of the diluent is less than 100 ml, the uncertainty of the measurement also increases. Thus, a 100 ml volume of diluent is the ideal volume to minimize the uncertainty in the analysis of iron.
