A hot lump of 30.5 g of iron at an initial temperature of 52.7 °C is placed in 50.0 mL H2O initially at 25.0 °C and allowed to reach thermal equilibrium. What is the final temperature of the iron and water, given that the specific heat of iron is 0.449 J/(g·°C)? Assume no heat is lost to surroundings.
final= _______ degrees Celsius

Answers

Answer:

26.7°C

Explanation:

Using the formula; Q = m × c × ΔT

Where; Q = amount of heat

m = mass

c = specific heat

ΔT = change in temperature

In this question involving iron placed into water, the Qwater = Qiron

For water; m= 50g, c = 4.18 J/g°C, Initial temp= 25°C, final temp=?

For iron; m = 30.5g, c = 0.449J/g°C, Initial temp= 52.7°C, final temp=?

Qwater = -(Qiron)

m × c × ΔT (water) =- {m × c × ΔT (iron)}

50 × 4.18 × (T - 25) = - {30.5 × 0.449 × (T - 52.7)}

209 (T - 25) = - {13.6945 (T - 52.7)}

209T - 5225 = -13.6945T + 721.7

209T + 13.6945T = 5225 + 721.7

222.6945T = 5946.7

T = 5946.7/222.6945

T = 26.7

Hence, the final temperature of water and iron is 26.7°C

Which of the following types of soil has the greatest permeability?

A. Loam

B. Sandy

C. Clay

D. Silty

Answers

Answer:

Sandy soil

Explanation:

Sandy soil has the greatest permeability of all soil types. It has a high amount of pore space and grain size.

Permeability is the ability of fluids to pass between the grains of a substance, here soil. It is usually a function of the size of the pore spaces and the grain size.

Sandy soils are usually made up of particles with sand-sized shapes and dimension. They have bigger and finer grains with little to no cement. This allows for a high level of permeability with no impediment to flow.Clay soil has very fine grain and with very low permeability. Silty soils have fair enough permeability and the permeability of loam straddles between that of sand and clay.

Permeability is very important for determining the quality of soils.

An atom of an element contains 6 protons, 6 neutrons, and 6 electrons. An atom that is a different isotope of this element would contain —

B.
6 protons, 6 neutrons, and 7 electrons.


C.
7 protons, 6 neutrons, and 6 electrons.


D.
7 protons, 7 neutrons, and 7 electrons.

Answers

Answer:

A

Explanation:

An atom that is a different isotope of a given element would contain 6 protons, 7 neutrons, and 6 electrons. Therefore, option (A) is correct.

What is an isotope?

Isotopes are atoms of an element that contain the same atomic number as the original element but a different atomic mass. Isotopes of an element possess the same number of electrons and the number of protons but different numbers of neutrons in their respective nucleus.

For example, the isotopes of carbon are carbon-14, carbon-13, and carbon-12. Carbon-14 has a total of 8 neutrons, carbon-13 have a total of 7 neutrons, and carbon-12 has a total of 6 neutrons. So all the isotopes of carbon have different numbers of neutrons.

Given element has 6 protons, 6 neutrons, and 6 electrons. So the isotope of this element will have  6 protons, and 6 electrons but not 6 neutrons. Therefore, the element with 6 protons, 7 neutrons, and 6 electrons is the isotope of the given element.

The molar absorptivity of a compound at 500 nm wavelength is 252 M-1cm-1. Suppose one prepares a solution by dissolving 0.00140 moles of a solute in enough water to make a 500.0 mL solution. What would be the absorbance in a 3 .00 mm pathlength cell?

Answers

Answer:

The absorbance of the solution is 0.21168.

Explanation:

Given that,

Wavelength = 500 nm

Molar absorptivity = 252 M⁻¹ cm⁻¹

Number of moles = 0.00140

Volume of solution = 500.0 mL

Length = 3.00 mm

We need to calculate the molar concentration

Using formula of the molar concentration

[tex]C=\dfrac{N}{V}[/tex]

Where, N = number of moles

V = volume

Put the value into the formula

[tex]C=\dfrac{0.00140}{0.5000}[/tex]

[tex]C=0.0028\ M[/tex]

We need to calculate the absorbance of the solution

Using formula of absorbance

[tex]A=\epsilon C l[/tex]

Put the value into the formula

[tex]A=252\times0.0028\times0.300[/tex]

[tex]A=0.21168[/tex]

Hence, The absorbance of the solution is 0.21168.

The absorbance of a compound, with a molar absorptivity at 500 nm wavelength of 252 M⁻¹ cm⁻¹, prepared by dissolving 0.00140 moles of a solute in enough water to make a 500.0 mL solution, measured in a 3 .00 mm pathlength cell, is 0.212.

First, we will calculate the molarity of the compound, which is equal to the moles of solute divided by the liters of solution.

[tex]M = \frac{0.00140mol}{0.5000L} = 0.00280 M[/tex]

Then, we will convert 3.00 mm to cm using the conversion factor 1 cm = 10 mm.

[tex]3.00 mm \times \frac{1cm}{10mm} = 0.300 cm[/tex]

Finally, we will calculate the absorbance of the compound using the Beer–Lambert equation.

[tex]A = \epsilon \times b \times C[/tex]

where,

A: absorbanceε: molar absorptivityb: length of light pathC: molar concentration

[tex]A = \epsilon \times b \times C = \frac{252}{M.cm} \times 0.300 cm \times 0.00280 M = 0.212[/tex]

The absorbance of a compound, with a molar absorptivity at 500 nm wavelength of 252 M⁻¹ cm⁻¹, prepared by dissolving 0.00140 moles of a solute in enough water to make a 500.0 mL solution, measured in a 3 .00 mm pathlength cell, is 0.212.

an object has a mass of 57.6g . find the object's density, given that's it's volume is 40.25cm^3​

Answers

Answer:

The answer is 1.43 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass = 57.6 g

volume = 40.25 cm³

We have

[tex]density = \frac{57.6}{40.25} \\ = 1.431055900...[/tex]

We have the final answer as

1.43 g/mL

Hope this helps you

Given: mass = 57.6 g, volume = 40.25 cm3
Unknown: density
Density = mass/volume
density = 57.6 g/40.25 cm3
density =1.43 g/ cm3
