Five observable properties for separating mixtures are particle size, colour, texture, shape, magnetic attraction.

Mixtures are compounds that are made up of two or more chemical compounds which are not linked to each other chemically. They can be easily separated.

The mixtures can be separated by properties like particle size, colour, density, shape, magnetic attraction.

Sieving can be used to separate compounds based on particle size. Chromatography can be used to separate compounds based on colour as each colour would have differences in properties. Flotation can be used to separate compounds based on density like oil in water. Centrifugation can be used to separate compounds based on shape. Magnetic separation can be used to separate metals from non-metal compounds in a mixture.

A certain red light has a wavelength of 680 nm. then, The frequency of the light is 4.4×10^14 s^-1 .

Given,

A certain red light had a wavelength = 680nm

frequency is given by,

f =c/λ

where, f = frequency

c = speed of light = 3×10^8 m/s

λ = wavelength = 680nm

f = (3×10^8 ) /(680× 10^-9 )

f = 0.0044×10^17 = 4.4×10^14 s^-1

Hence, the frequency of the light is 4.4×10^14 s^-1 .

The distance between the two crests or troughs of the light wave is known as the wavelength of light. Using the Greek letter lambda (), it is identified. As a result, wavelength refers to the separation between one wave's crest or dip and the following wave.

The formula for wavelength is given by,

wavelength= speed of light /frequency

According to the definition of frequency, it is the quantity of full wave cycles that pass a spot in a unit of time.

Hertz is the SI unit for frequency (Hz).

The number of full oscillations that any wave element makes in one unit of time is the frequency of a sinusoidal wave.

Frequency is in periodic motion; after going through a number of different situations or postures and then returning to its initial place, it has completed one cycle.

The reciprocal of a wave's period is equal to the wave's frequency.

The frequency mathematical expression is:

frequency = speed of light / wavelength

The length of time it takes for any string element to complete an oscillation is known as a wave's oscillation period.

Answer:

The value of the Golden Igloo is $227.4 million.

Explanation:

First, we need to find the inner and the outer volume of the half-spherical shell:

\( V_{i} = \frac{1}{2}*\frac{4}{3}\pi r_{i}^{3} \)

\( V_{o} = \frac{1}{2}*\frac{4}{3}\pi r_{o}^{3} \)

The total volume is given by:

\( V_{T} = V_{o} - V_{i} \)

Where:

\( V_{i} \): is the inner volume

\(r_{i}\): is the inner radius = 1.25/2 = 0.625 m

\( V_{o} \): is the outer volume

\(r_{o}\): is the outer radius = 1.45/2 = 0.725 m

Then, the total volume of the Igloo is:

\( V_{T} = \frac{2}{3}\pi r_{o}^{3} - \frac{2}{3}\pi r_{i}^{3} = \frac{2}{3}\pi [(0.725 m)^{3} - (0.625 m)^{3}] = 0.29 m^{3} \)

Now, by using the density we can find the mass of the Igloo:

\( m = 19.3 \frac{g}{cm^{3}}*0.29 m^{3}*\frac{(100 cm)^{3}}{1 m^{3}} = 5.60 \cdot 10^{6} g \)

Finally, the value (V) of the antiquity is:

\( V = \frac{\$ 1263}{oz}*5.60 \cdot 10^{6} g*\frac{1 oz}{31.1034768 g} = \$ 227.4 \cdot 10^{6} \)  

Therefore, the value of the Golden Igloo is $227.4 million.

The number of moles of the gas sample is 1.0 mol.

The ∆s°rxn for the given reaction is -112.3 J/mol⋅K.

To calculate ∆s°rxn for the given reaction, we need to use the following formula:
∆s°rxn = Σs°(products) - Σs°(reactants)
Here, the reactants are C2H2(g) and H2(g), and the product is C2H4(g). The values of s° for each species are given as follows:
s°(C2H2) = 200.9 J/mol⋅K

Now, we can substitute these values into the formula and get:
∆s°rxn = [s°(C2H4)] - [s°(C2H2) + s°(H2)]
∆s°rxn = [219.3] - [200.9 + 130.7]
∆s°rxn = [219.3] - [331.6]
∆s°rxn = -112.3 J/mol⋅K

The empirical formula of the compound is CH2O.

To find the empirical formula of the compound, we need to determine the ratios of the atoms in the compound. To do this, we need to find the number of moles of each element present in the compound.

The molar mass of carbon is 12.01 g/mol, the molar mass of hydrogen is 1.008 g/mol, and the molar mass of oxygen is 16.00 g/mol. The number of moles of carbon in the sample is:0.1565 g × 1 mol/12.01 g ≈ 0.0130 mol. The number of moles of hydrogen in the sample is:0.02627 g × 1 mol/1.008 g ≈ 0.0261 molThe number of moles of oxygen in the sample is:

0.4170 g × 1 mol/16.00 g ≈ 0.0261 mol

Now that we know the number of moles of each element, we can determine the simplest whole number ratio of the elements in the compound. We can do this by dividing each number of moles by the smallest number of moles. In this case, the smallest number of moles is 0.0130 mol.

We get:

Carbon: 0.0130 mol ÷ 0.0130 mol = 1

Hydrogen: 0.0261 mol ÷ 0.0130 mol = 2

The mass of gallium (Ga) that can be deposited is 1.96 grams.

Using Faraday's equation of electrolysis, which states that the mass of a substance deposited or liberated during electrolysis is directly proportional to the amount of electricity passing through the electrolyte, we may determine the mass of gallium that can be deposited from a Ga(III) solution.

First, we need to calculate the total charge (Q) passed through the electrolyte using the formula
Q = I × t,
where I is the current (0.560 A) and
t is the time(70.0 min × 60 s/min).

The next step is to divide the charge by Faraday's constant (F = 96,485 C/mol), which will give us the number of moles of electrons that were transported.

We will deposit one mole of gallium for every mole of electrons transported since gallium has a 3+ charge.

As a result, the amount of electrons transported and the amount of gallium deposited are equal.

The mass of gallium deposited is then calculated by dividing the number of moles of gallium by its molar mass (69.72 g/mol).

After performing the computations, we discover that 1.96 grammes of gallium can be deposited.

The concentration of ClO⁻ in the mixture is 0.055 M, rounded to two significant figures, calculated with the help of equilibrium constant.

The reaction between HF and ClO⁻ is:

HF + ClO⁻ → HClO + F⁻

The equilibrium constant expression for this reaction is:

K = [HClO][F⁻]/[HF][ClO⁻]

We are given the initial concentrations of HF and HClO, but not the concentration of F⁻. However, since HF and HClO react to form F⁻, the concentration of F⁻ is equal to the concentration of HF that has reacted. Let x be the concentration of F⁻ and let y be the concentration of ClO⁻. Then, we have:

[HClO] = 0.150 M - x

[F⁻] = x

[HF] = 0.300 M - x

[ClO-] = y

Substituting these concentrations into the equilibrium constant expression, we get:

K = (0.150 - x)(x)/(0.300 - x)(y)

At equilibrium, the reaction quotient Q is equal to the equilibrium constant K. Therefore, we can set Q = K and solve for y:

K = Q = (0.150 - x)(x)/(0.300 - x)(y)

y = (0.150 - x)(x)/(0.300 - x) / K

We are not given a value for K, so we need to calculate it. The value of K for this reaction can be found in a chemistry reference book or online. According to the CRC Handbook of Chemistry and Physics, the value of K for this reaction is 3.5 x 10⁻⁴ at 25°C.

Substituting this value for K and x = [F⁻] into the equation for y, we get:

y = (0.150 - x)(x)/(0.300 - x) / K

y = (0.150 - x)(x)/(0.300 - x) / 3.5 x 10⁻⁴

y = 0.041 x/(0.300 - x)

Substituting the initial concentration of HF into the expression for x, we get:

x = [F⁻] = [HF] reacted = 0.300 M - 2x

Substituting this expression for x into the expression for y, we get:

y = 0.041(0.300 - 2x)/(0.300 - x)

y = 0.041(0.300 - 2(0.300 - x))/(0.300 - (0.300 - x))

y = 0.041(2x - 0.150)/x

Simplifying this expression, we get:

y = 0.0828 - 0.274x

Substituting the value of x = 0.100 M (which is half of the initial concentration of HF that has reacted), we get:

y = 0.0552.

If the initial amount of radionuclide is 50 mci and the half-life is 75 days. Then, the activity remaining after 200 days is approximately 2.19515 mCi.

To determine the activity remaining after a certain time, we can use the radioactive decay equation;

A = A₀ × \((1/2)^{(t}\) / T₁/₂)

Where; A is the remaining activity after time t

A₀ is the initial activity

T₁/₂ is the half-life of the radionuclide

Given; A₀ = 50 mCi (millicuries)

T₁/₂ = 75 days

t = 200 days

Plugging in the values into the equation, we get;

A = 50 mCi × (1/2)²⁰⁰ / 75)

Calculating this expression, we find;

A ≈ 50 mCi × 0.043903
