Answer:

See explanation

Explanation:

A saturated solution is a solution that contains just as much solute as it can normally hold at that temperature.

If the temperature is cooled and  crystals of copper sulphate are formed in the solution, then the solution is no longer saturated because some solute are now leaving the solution.

b) percent by mass = mass of solute/mass of solution * 100

percent by mass = 20%

mass of solute = x g

mass of solution =  80 g​

20 = x/80 * 100

1600 = 100x

x = 1600/100

x = 16 g

Schrodinger's Quantum Mechanical Model, which is currently recognised by modern science, is the electron model. The electron cloud model is another name for this one.

The term "electron cloud" refers to the current atomic structure model. A physicist from Austria named Edwin Schrodinger argued that electrons do not follow static or permanent trajectories.

The contemporary atomic model, often known as the cloud model, depicts atoms as having a nucleus made up of protons and neutrons and a diffuse gradient or cloud surrounding it that is made up of electrons. Because electron activity is probabilistic, electrons are often depicted as clouds.

Answer:

d=m/

Explanation:

d is density, m is mass, v is volume

Given: m =10.4g, v=12.2mL

substituting in equation,

d=10.4/ 12.2

d=0.8524g/mL

To learn more about density:

The density of the liquid is 0.852 g/mL.

To calculate the density of the liquid, we need to use the formula:

Density = Mass / Volume

Given that the mass of the liquid is 10.4 g and the volume is 12.2 mL, we can substitute these values into the formula:

Density = 10.4 g / 12.2 mL

Simplifying this expression, we find:

Density = 0.852 g/mL

Density is a physical property of a substance and is defined as the amount of mass per unit volume. In this case, the density tells us that for every milliliter of the liquid, there is 0.852 grams of mass. The units of grams per milliliter (g/mL) indicate that the density is a ratio of mass to volume.It is important to note that the density of a substance can vary with temperature, so this value is only valid under the conditions at which the measurement was made. Additionally, the density can provide valuable information about the identity of a substance, as different substances have different densities.

Answer:

56.96 grams

Explanation:

To find the mass of 1.78 moles of O2, we need to use the molar mass of O2, which is the mass of one mole of O2.

The chemical formula for O2 is O-O or simply O2. The molar mass of O2 is the sum of the atomic masses of two oxygen atoms, which can be found on the periodic table.

The atomic mass of oxygen (O) is approximately 16.00 g/mol. So the molar mass of O2 is:

Molar mass of O2 = 2 x atomic mass of O

= 2 x 16.00 g/mol

= 32.00 g/mol

Therefore, the mass of 1.78 moles of O2 is:

Mass = number of moles × molar mass

= 1.78 mol × 32.00 g/mol

= 56.96 g

So the mass of 1.78 moles of O2 is 56.96 grams.

If a reaction has a negative ΔG and a positive ΔS, the reaction will be spontaneous at all temperatures.

If a reaction is spontaneous at all temperatures, it implies that the reaction will occur without the need for any external intervention, such as the addition of energy. For a reaction to be spontaneous, it must satisfy the criteria of thermodynamic favorability, which is determined by the change in Gibbs free energy (ΔG) associated with the reaction.

The relationship between ΔG, temperature (T), and the equilibrium constant (K) of a reaction is described by the equation ΔG = ΔH - TΔS, where ΔH is the change in enthalpy and ΔS is the change in entropy.

To ensure spontaneity at all temperatures, two conditions must be met:

ΔG must be negative: A negative ΔG indicates a thermodynamically favorable reaction, meaning the products have a lower Gibbs free energy than the reactants. If ΔG is negative, the reaction will proceed spontaneously in the forward direction.

ΔS must be positive: A positive ΔS signifies an increase in the overall entropy of the system. Higher entropy means more disorder, and spontaneous reactions often involve an increase in randomness. When ΔS is positive, it can compensate for the enthalpic term, ΔH, allowing the reaction to proceed spontaneously.

melting point

Reactivity with a strong acid

Explanation:

The ability to conduct electricity is a physical property of copper. Most electrical cables are made of copper owing to its high electrical conductivity.

The rusting of iron is a chemical reaction. Rust is actually hydrated iron III oxide. Hence it is a chemical property of iron.

The melting points of metals can be used to classify them. The greater the density of metals, the higher their melting point.

The ability of metals to react with acids separates metals into highly reactive, moderately reactive and unreactive metals.

Copper shows physcal property & iron shows chemical property.

Physical properties are those properties which are seen by the eye due to change in the outermost appearance, whereas chemical properties are those which are shown due to change in the internal composition.

In the question, it is given that copper metal has a ability to conduct electricity and this property of metal is the physical property, as due to conduction their identity is not changing.

It is also given that iron is showing rusting due to the formation of iron oxide, so it a chemical property as identity of iron changes.

So, scientists characterize certain metals, they investigate physical properties like melting point, conductivity, density, etc. and chemical properties like reactivity with acid, base, oxygen, etc.

Hence, the ability to conduct electricity is a physical property of Cu and the ability of iron to rust is a chemical property.

The N/Z ratio for 136Sm is 1.16

N/Z ratio is the ratio of number of neutrons and protons present in the nucleus of an atom.

The ratio of neutrons to protons is very important in determining nuclear stability. If there are more protons in the nucleus, the nucleus will require more neutrons to bind the nucleus together. This is because as the size of the nucleus increases, the electrostatic repulsion between the protons gets weaker.

Given,

The nucleus of Sm has :

Number of protons = 62

Mass number = 136

Number of neutrons = mass number - number of protons

                                  = 136 - 62

                                   =72

         N/Z ratio = \(\frac{number of neutrons}{number of protons}\)

                        = \(\frac{72}{62}\)
