Answer:

In the formation of 1 formula unit of Al2O3 in the reaction 4Al + 3O2 → 2Al2O3, a total of 12 electrons are transferred, with each aluminum atom gaining 3 electrons through oxidation and each oxygen molecule gaining 4 electrons through reduction.

Explanation:

In the oxidation-reduction reaction equation: 4Al + 3O2 → 2Al2O3, the reaction involves the oxidation of aluminum (Al) and the reduction of oxygen (O2). The formation of 1 formula unit of the product Al2O3 involves the transfer of a specific number of electrons.

To determine the number of electrons transferred, we need to look at the change in oxidation states of the elements involved. In this case, aluminum (Al) is oxidized from an oxidation state of 0 to +3, while oxygen (O) is reduced from an oxidation state of 0 to -2.

Each aluminum atom gains three electrons during the oxidation process, as its oxidation state increases from 0 to +3. Considering that there are four aluminum atoms in the reaction, a total of 4 × 3 = 12 electrons are transferred due to the oxidation of aluminum.

On the other hand, each oxygen molecule (O2) gains four electrons during the reduction process, as its oxidation state decreases from 0 to -2. Since there are three oxygen molecules in the reaction, a total of 3 × 4 = 12 electrons are transferred due to the reduction of oxygen.

Answer:

true

Explanation:

Answer:

There is 9.6 grams of CO2 produced

Explanation:

Step 1: Data given

Mass of methane = 5.50 grams

Molar mass of methane = 16.04 g/mol

Mass of oxygen = 13.9 grams

Molar mass of oxygen = 32.0 g/mol

Step 2: The reaction

CH4(g) + 2O2(g) → CO2(g) + 2H2O(g)

Step 3: Calculate number of moles

Moles = mass / molar mass

Moles methane = 5.50 grams / 16.04 g/mol

Moles methane = 0.343 moles

Moles oxygen = 13.9 grams / 32.0 g/mol

Moles oxygen = 0.434 moles

For 1 mol CH4 we need 2 moles O2 to produce 1 mol CO2 and 2 moles H2O

O2 is the limiting reactant. It will completely react (0.434 moles).

There will react 0.434/2 = 0.217 moles CH4

There will remain 0.343-0.217 = 0.126 moles CH4

There will be produced 0.434 moles of H2O and

0.434/2 =0.217 moles of CO2

Step 4: Calculate mass of products

Mass = moles * molar mass

Mass CO2 = 0.217 moles ¨44.01 g/mol

Mass CO2 = 9.6 grams

Mass H2O = 0.434 moles * 18.02

Mass H2O = 7.8 grams

The energy efficiency of a fuel cell can be calculated by dividing the electrical energy output by the energy input. In a fuel cell, the energy input refers to the chemical energy stored in the fuel that is converted to electrical energy through a redox reaction.

This redox reaction is spontaneous, meaning that it releases energy when it occurs. Therefore,  energy input is calculated by measuring the heat released by the reaction, which is proportional to the chemical energy of  fuel. The energy output is determined by measuring the electrical energy produced by  fuel cell. The energy efficiency is expressed as  percentage, where the higher the percentage, more efficient the fuel cell is in converting chemical energy to electrical energy.

With ions of calcium in a cyclotron. This produced four atoms of moscovium. Moscovium is a synthetic element with the symbol Mc and atomic number 115. It was first synthesized in 2003 by a joint team of Russian and American scientists at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia. In December 2015, it was recognized as one of four new elements by the Joint Working Party of international scientific bodies IUPAC and IUPAP. On 28 November 2016, it was officially named after the Moscow Oblast, in which the JINR is situated.[7][8][9]

Moscovium is an extremely radioactive element: its most stable known isotope, moscovium-290, has a half-life of only 0.65 seconds.[10] In the periodic table, it is a p-block transactinide element. It is a member of the 7th period and is placed in group 15 as the heaviest pnictogen, although it has not been confirmed to behave as a heavier homologue of the pnictogen bismuth. Moscovium is calculated to have some properties similar to its lighter homologues, nitrogen, phosphorus, arsenic, antimony, and bismuth, and to be a post-transition metal, although it should also show several major differences from them. In particular, moscovium should also have significant similarities to thallium, as both have one rather loosely bound electron outside a quasi-closed shell. Over a hundred atoms of moscovium have been observed to date, all of which have been shown to have mass numbers from 286 to 290.

Answer:

15 g of CaCo₃

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

CaO + CO₂ —> CaCo₃

From the balanced equation above,

1 mole of CaO reacted to produce 1 mole of CaCo₃.

Next, we shall determine the number of mole of CaCo₃ produced by the reaction of 0.15 mole of CaO. This can be obtained as follow:

From the balanced equation above,

1 mole of CaO reacted to produce 1 mole of CaCo₃.

Therefore, 0.15 mole of CaO will also react to produce 0.15 mole of CaCo₃.

Finally, we shall determine the mass of 0.15 mole of CaCo₃. This can be obtained as follow:

Mole of CaCo₃ = 0.15 mole

Molar mass of CaCo₃ = 40 + 12 + (16×3)

= 40 + 12 + 48

= 100 g/mol

Mass of CaCo₃ =?

Mole = mass / Molar mass

0.15 = Mass of CaCo₃ / 100

Cross multiply

Mass of CaCo₃ = 0.15 × 100

Mass of CaCo₃ = 15 g

Thus, 15 g of CaCo₃ were obtained from the reaction.

(a) The zone axis for (111) plane is a line that passes through the origin and is perpendicular to the (111) plane

For the (112) plane, the zone axis is a line that passes through the origin and is parallel to the face diagonal of the crystal lattice

For the (001) plane, the zone axis is a line parallel to the plane and perpendicular to the crystal lattice.

(b)The angle between the (111) and (112) planes is approximately 35.26°.

(c) The inter-planar distance between the {112} planes is approximately 0.157 nm.

(a) Zone axis:

The zone axis for the (111) plane is a line that passes through the origin and is perpendicular to the (111) plane. It represents the direction along which the crystal lattice repeats itself. For the (112) plane, the zone axis is a line that passes through the origin and is parallel to the face diagonal of the crystal lattice. For the (001) plane, the zone axis is a line parallel to the plane and perpendicular to the crystal lattice.

(b) Angle between the (111) and (112) planes:

To find the angle between the (111) and (112) planes, we can use the formula:

cos(θ) = (h1h2 + k1k2 + l1l2) / (sqrt(h1^2 + k1^2 + l1^2) * sqrt(h2^2 + k2^2 + l2^2))

Given that the Miller indices for the (111) plane are (1, 1, 1) and for the (112) plane are (1, 1, 2), we can substitute these values into the formula:

cos(θ) = (11 + 11 + 1*2) / (sqrt(1^2 + 1^2 + 1^2) * sqrt(1^2 + 1^2 + 2^2))

cos(θ) = 7 / (sqrt(3) * sqrt(6))

Taking the inverse cosine of both sides, we find:

θ = cos^(-1)(7 / (sqrt(3) * sqrt(6)))

Therefore, the angle between the (111) and (112) planes is approximately 35.26°.

(c) Inter-planar distance between the {112} planes:

To calculate the inter-planar distance, we can use Bragg's law:

nλ = 2d * sin(θ)

Where n is the order of the reflection, λ is the wavelength of the X-ray, d is the inter-planar distance, and θ is the angle between the incident X-ray beam and the crystal plane.

For the {112} planes, the Miller indices are (1, 1, 2). Assuming a typical X-ray wavelength of 1.54 Å (0.154 nm), and using the angle θ calculated in part (b), we can solve for the inter-planar distance, d:

0.154 nm = 2d * sin(35.26°)

d = 0.154 nm / (2 * sin(35.26°))

Therefore, the inter-planar distance between the {112} planes is approximately 0.157 nm.
