The minimum entropy change of the heat-supplying source is -0.87 kJ/K.

In this case, given the initial conditions, we first use the 10-% quality to compute the initial entropy.

S₁ = 1.485  +  (0.1)(5.6865) = 2.0537 kJ/kg K

The entropy at the final state given the new 40-% quality:

S₂ = 1.4337  +  (0.4)(5.7894) = 3.7495 kJ/kg K

m₁ = 0.026/(0.001057   +  0.1 x 1.002643) = 0.257 kg

m₂ = 0.026/(0.001053   +  0.4 x 1.158347)  = 0.056 kg

ΔS + S₁  - S₂  + S₂m₂  - S₁m₁  -  sfg(m₂  -  m₁)  > 0

ΔS + 2.0537 -  3.7495 + (3.7495 x 0.056)  -   (2.0537 x 0.257)  - 5.6865( 0.056 - 0.257)  >  0

ΔS > -0.87 kJ/K

Thus, the minimum entropy change of the heat-supplying source is -0.87 kJ/K.

The following statements about subatomic particles are correct:

B. The charge on a proton is equal in magnitude and opposite in sign to that of an electron

C. The mass of a proton is similar to that of a neutron

D. The mass of a neutron is slightly greater than that of an electron.

Subatomic particles refer to the basic building blocks of matter that make up atoms. The main subatomic particles are:

Protons: Positively charge particles found in the nucleus of an atom. The number of protons in an atom determines the atomic number, and thus the identity, of the element.

Neutrons: Neutral particles found in the nucleus of an atom. The number of neutrons in an atom can vary, resulting in isotopes of the same element.

Electrons: Negatively charged particles that orbit the nucleus of an atom. The number of electrons in an atom determines its chemical properties and reactivity.

These subatomic particles interact with each other through electromagnetic forces to form the atoms and molecules that make up matter. Understanding the behavior and interactions of subatomic particles is key to understanding the properties and behavior of matter on a macroscopic scale.

The climatic change in Earth's history that has resulted in glaciers is the cold climate.

During the last 2.6 million years, the Earth has experienced a series of ice ages, or periods of colder global climate, which have led to the growth of glaciers in regions with sufficient snowfall.

These colder periods are associated with changes in the Earth's orbit, tilt, and precession, which affect the amount and distribution of solar radiation received by the Earth. These climatic changes have had significant impacts on the Earth's surface and have influenced the evolution of life on our planet.

\(\boxed {\tt Carbohydrate \ or \ monosaccharides}\)

Explanation:

There are 4 main types of macromolecules: lipids, proteins, carbohydrates, and nucleic acids.

If you are looking for some quick energy, the best choice is carbohydrates. Carbohydrates are the easiest for the body to break down and turn into ATP/energy.

There are also different types of carbohydrates. If you want a more specific answer, monosaccharides is the best answer. They are the simplest sugars. Also, glucose is a monosaccharide, and it shows up directly in the cellular respiration formula. If glucose is consumed, the body doesn't have to break it down before starting respiration.

The metal X has an approximate molar mass of 42.36 g/mol and the metal is most likely calcium.

The molar mass of the metal carbonate XCO₃ and identify the metal X, we need to calculate the number of moles of XCO₃ and CO₂ using the given masses and molar masses.

The molar mass of CO₂ (carbon dioxide) is 12.011 g/mol (for carbon) + 2 * 15.999 g/mol (for oxygen) = 44.01 g/mol.

The number of moles of CO₂ can be calculated using the formula:

moles of CO₂ = mass of CO₂ / molar mass of CO₂

moles of CO₂ = 0.855 g / 44.01 g/mol

moles of CO₂ ≈ 0.01944 mol

Since the reaction stoichiometry is 1:1 between XCO₃ and CO₂, the number of moles of XCO₃ is also approximately 0.01944 mol.

molar mass of XCO₃ = mass of XCO₃ / moles of XCO₃

molar mass of XCO₃ = 2.012 g / 0.01944 mol

molar mass of XCO₃ ≈ 103.38 g/mol

The molar mass of XCO₃ is approximately 103.38 g/mol.

To determine the metal X:

molar mass of X = molar mass of XCO3 - molar mass of CO3

molar mass of X = 103.38 g/mol - (12.011 g/mol + 3 * 15.999 g/mol)

molar mass of X ≈ 42.36 g/mol

Metal X is most likely Calcium that has a molar mass of 40 g/mol

Sedimentation, filtration, and coagulation are the treatments that will help remove contaminants from minerals or from the pipes carrying water from a source.

Sedimentation is a process in which suspended particles settle out of water. It is one of the most basic techniques for removing particles from water. As particles settle, they become trapped in the bottom of a container or settle to the ground in an outdoor setting

Filtration is a method of removing particles from a fluid. It is a physical or chemical separation method that separates solids from fluids (liquids or gases) by adding a medium through which only the fluid can pass.

Coagulation is the process of using chemicals to remove contaminants from water. By creating a chemical reaction, coagulation destabilizes particles and causes them to clump together. This helps to remove the contaminants from the water.

Disinfection is the process of eliminating or destroying pathogens that cause infection. Disinfection eliminates harmful microorganisms by destroying or inactivating them. The disinfectant is a chemical or physical agent that is used to destroy or inactivate harmful microorganisms.

Explanation:

Answer:

3960/min

Explanation:

The rate constant is expressed in seconds (s): 66 s⁻¹ = 66/s

We know that: 1 min = 60 s

Conversion factor = 60 s/1 min

We multiply the rate constant by the conversion factor to obtain the rate constant expressed in units of minutes:

rate constant = 66/s x 60 s/1 min = 3960/min

The rate constant of a first order reaction in units of minutes is equal to 3960 / min.

Rate constant of any chemical reaction given knowledge about the speed and the direction of the reaction.

In the question, given that

Rate constant of a first order reaction = 66 per sec.

We know that in 1 min = 60 seconds are present.

So, we multiply the given value by 60/1 sec/min to convert into minutes units.

Rate constant of a first order reaction = 66 per sec × 60/1 sec per min = 3960 per min.

Hence, 3960 per min is the rate constant in units of minutes.

Explanation:

Hello there!

in this case, according to the given information, it turns out firstly necessary for us to write up the chemical equation as shown below:

\(BaCl_2+Na_2SO_4\rightarrow BaSO_4+2NaCl\)

Thus, we calculate the mass of BaCl2 stoichiometrically related to the produced 1.658 g of precipitate in order to discard it from the sample:

\(m_{BaCl_2}=1.658gBaSO_4*\frac{1molBaSO_4}{233.38 gBaSO_4} *\frac{1molBaCl_2}{1molBaSO_4}*\frac{208.23 gBaCl_2}{1molBaCl_2}\\\\m_{BaCl_2}=1.479gBaCl_2\)

Thus, the mass percentage is calculated as shown below:

\(\% m=\frac{1.479g}{3.656g}*100 \% \\\\\% m=40.46\%\)

The pressure exerted by a confined gas is the result of Option b. gas particles colliding with the walls of the container.

The pressure exerted by a confined gas is the result of gas particles colliding with the walls of the container. When a gas is confined within a container, the gas particles are in constant motion, moving in random directions with varying speeds. As these gas particles move, they collide with each other and with the walls of the container.

When a gas particle collides with the walls of the container, it exerts a force on the surface. The collective effect of numerous gas particle collisions leads to a net force being exerted on the walls of the container. This force per unit area is what we call pressure.

The more frequently and vigorously the gas particles collide with the walls, the higher the pressure of the gas. Factors that influence gas pressure include the number of gas particles present, their average speed, and the volume of the container. Therefore, Option b is correct.
