Answer: The balanced chemical equation for the reaction between aluminum (Al) and copper(II) sulfate (CuSO4) is:

2 Al (s) + 3 CuSO4 (aq) → Al2(SO4)3 (aq) + 3 Cu (s)

From the balanced equation, we can see that 2 moles of Al react with 3 moles of CuSO4 to produce 1 mole of Al2(SO4)3 and 3 moles of Cu. We can use this information to calculate the theoretical yield of Al2(SO4)3 that can be produced from a given amount of Al.

To do this, we first need to convert the mass of Al given in the problem to moles using its molar mass. The molar mass of Al is 26.98 g/mol, so:

459.7 g Al × (1 mol Al / 26.98 g Al) = 17.03 mol Al

We can then use the mole ratio from the balanced equation to calculate the moles of Al2(SO4)3 that can be produced:

2 mol Al : 1 mol Al2(SO4)3

17.03 mol Al : x mol Al2(SO4)3

x = (17.03 mol Al) / 2 × (1 mol Al2(SO4)3 / 1 mol Al) = 8.52 mol Al2(SO4)3

Finally, we can convert the moles of Al2(SO4)3 to grams using its molar mass:

Molar mass of Al2(SO4)3 = 342.15 g/mol

Mass of Al2(SO4)3 = 8.52 mol Al2(SO4)3 × (342.15 g/mol) = 2915 g

Therefore, approximately 2915 grams of aluminum sulfate (Al2(SO4)3) are produced from 459.7 grams of aluminum (Al) reacting with copper(II) sulfate (CuSO4).

Answer:

B

17.6%

Explanation:

1. Percentage yield = (Actual yield/theoretical yield) x 100

2. You know actual yield of ammonia (60kg) so you need to work out theoretical yield.

3. mols of hydrogen = m/mr = 60,000/2 = 30,000 mols.

4. 3:2 ratio so (30,000/3) x 2 = 20,000 mols of Ammonia.

5. Therefore mass of ammonia = mr x mols = 20,000 x 17 = 340,000 grams

6. So percentage yield is (60,000/340,000) x 100 = 17.6

Diatomic elements are written with a subscript of 2 when they exist as a pure diatomic molecule in nature.

Diatomic elements are elements that exist in nature as two atoms of the same element bonded together. These elements include hydrogen (H₂), nitrogen (N₂), oxygen (O₂), fluorine (F₂), chlorine (Cl₂), bromine (Br₂), and iodine (I₂). Diatomic molecules are important in chemistry because they represent the simplest possible form of a covalent bond. They have an even number of electrons in their bonding molecular orbital, which makes them stable and nonpolar.

When diatomic elements are written in a chemical equation, they are written with a subscript of 2. This is because the chemical formula for a diatomic molecule consists of two atoms of the same element. For example, the chemical formula for hydrogen gas is H₂, and the chemical formula for oxygen gas is O₂. This notation helps to distinguish between elements that exist as single atoms (such as helium, He) and elements that exist as diatomic molecules (such as hydrogen, H₂).

Explanation:

(a) To get the pH of the media to 5.8, you would add NaOH solution. NaOH is used as a basic solution, and when it is added to a solution, it will increase the pH of the solution.

(b) The molecular weight of BA is 225.3. To prepare a 1M solution, you would have to weigh out 225.3 grams of BA.(c) To convert a 1M solution of BA to mg/mL, you can use the following equation: 1 mole = molecular weight in grams; 1000 millimoles = 1 mole. So, 1 M = 1000 mg/mL. Therefore, a 1M solution of BA is equivalent to 1000 mg/mL .(d) To convert a concentration of 1000 mg/mL .

Therefore, to calculate the weight required for a 5 mM solution, use the following formula :Mass of BA = molarity × volume × molecular weight= 5 × 0.001 × 225.3= 1.1265 grams(f) To convert a concentration of 5 mM to mg/mL, we use the following formula: Concentration (mg/mL) = (Concentration (mM) × Molecular weight) / 1000= (5 × 225.3) / 1000= 1.1265 mg/mL(g)

To convert a concentration of 1.1265 mg/mL to mg/L, we multiply by 1000, so 1.1265 mg/mL = 1126.5 mg/L.(h) Given that the stock solution of BA is 5 mM and the working solution is 0.2 mg/mL.

There are approximately 1.28 x 10²³ hydrogen atoms in 10.0 grams of menthol.

Menthol is chemical compound that is found naturally in peppermint and other similar plants.

molar mass of menthol = (10 x 12.01) + (20 x 1.01) + (2 x 15.99) = 156.27 g/mol

moles of menthol = mass of menthol / molar mass of menthol

moles of menthol = 10.0 g / 156.27 g/mol = 0.0639 mol

number of hydrogen atoms = moles of menthol x number of hydrogen atoms per mole

So, number of hydrogen atoms = 0.0639 mol x 20 = 1.28 mol

Answer:

the change in free energy for this reaction is approximately -317,940.65 J.by using formula of free energy change (ΔG) for a reaction is ΔG = ΔH - TΔS

To calculate the free energy change (ΔG) for a reaction, you can use the following equation:

ΔG = ΔH - TΔS

Where ΔG is the change in free energy, ΔH is the change in enthalpy, T is the temperature in Kelvin, and ΔS is the change in entropy.

Given:
ΔH = -255 kJ
ΔS = 211 J/K

First, we need to convert ΔH to J by multiplying by 1000:
ΔH = -255 kJ * 1000 J/kJ = -255,000 J

Now we need to know the temperature (T) in Kelvin to proceed. Assuming the reaction occurs at room temperature, 25°C:
T = 25°C + 273.15 = 298.15 K

Now we can calculate ΔG:
ΔG = ΔH - TΔS
ΔG = -255,000 J - (298.15 K * 211 J/K)

ΔG = -255,000 J - 62,940.65 J

ΔG = -317,940.65 J

Answer: The vapor pressure of ethanol at \(26.3^{o}C\) is 238.3 torr.

Explanation:

Given: \(\Delta H_{vap}\) = 38.6 kJ/mol

\(T_{1} = 26.3^{o}C = (26.3 + 273) K = 299.3 K\)

\(T_{2} = 78.4^{o}C = (78.4 + 273) K = 351.4 K\)

Formula used to calculate the vapor pressure of ethanol is as follows.

\(ln\frac{P_{2}}{P_{1}} = \frac{\Delta H_{vap}}{R} [\frac{1}{T_{1}} - \frac{1}{T_{2}}]\\\)

Substitute the values into above formula as follows.

\(ln\frac{P_{2}}{P_{1}} = \frac{\Delta H_{vap}}{R} [\frac{1}{T_{1}} - \frac{1}{T_{2}}]\\ \\ln \frac{760 torr}{P_{1}} = \frac{38600 J}{8.314 J/mol K}[\frac{1}{299.3} - \frac{1}{351.4}]\\\frac{760}{P_{1}} = 3.18\\P_{1} = 238.3 torr\)

The mass of manganese-56 in a 1.0mg sample remaining at the end of 10.4 hours is 0.0025mg

What is Half Life?

Half-life, in radioactivity, is the amount of time needed for half of a radioactive sample's atomic nuclei to decay (change spontaneously into other nuclear species by emitting particles and energy), or, alternatively, the amount of time needed for a radioactive material's rate of disintegrations per second to decrease by half.

Cobalt-60, a radioactive isotope used in radiotherapy, has a half-life of 5.26 years, for instance. As a result, after that time, a sample that contained 8 g of cobalt-60 at first would only have 4 g of cobalt-60 and would produce half as much radiation. Only 2 g of cobalt-60 would remain in the sample after an additional delay of 5.26 years. The initial sample's mass and volume don't change noticeably,

The half-life of 44ti can be calculated using the given information. The rate of decay is \(4.3*10^8\) disintegrations, and the initial sample size is 1.0 ng.

For finding the half-life, we can use the formula:

half-life = (ln(2)) / (decay constant)

First, we need to find the decay constant using the given rate of decay:

decay constant = rate of decay / initial sample size

decay constant = (4.3*10^8 disintegrations) / (1.0 ng)

Now, we can substitute the decay constant into the half-life formula:

half-life = ln(2) / (decay constant)

half-life = ln(2) / [(\(4.3*10^8\)  disintegrations) / (1.0 ng)]
