Answer:

See explanation

Explanation:

The principle of conservation of energy states that energy can neither be created nor destroyed but can be converted from one form to another. Hence, chemical energy in a battery can be converted to electrical energy.

Usually, the conversion of energy from one form to another is not 100% efficient according to the second law of thermodynamics. Some energy is wasted in the process, sometimes as heat.

Hence, in an ideal situation where no heat energy is produced; all the chemical energy is converted to electrical energy (100% energy conversion). There will be no energy loss if no heat is produced.

The ZnCl2 has a mass of  52.4 g.

The mass of NH3 is  12.24 g

Knowing that,

Zn number of moles is 25 g/65 g/mol.

= 0.385 mole

If 1 mole of zinc creates 1 mole of zinc chloride

0.385 mole of ZnCl2 is thus created.

ZnCl2 mass produced is 0.385 mole * 136 g/mol.

= 52.4 g

2) The formula for N2's moles is 10g/28 g/mol, or 0.36 moles.

30 moles of H2 are equal to 60 g divided by 2 g/mol.

If 3 moles of H2 and 1 mole of N2 react,

N2 interacts with 0.36 moles at 0.36 * 3/1.

= 1.08 moles

N2 is hence the limiting reactant.

2 moles of NH3 are produced from 1 mole of N2.

The result of 0.36 moles of N2 is 0.36 * 2/1.

= 0.72 moles

NH3 mass equals 0.72 moles times 17 g/mol.

= 12.24 g

The chemical associated with homeostatic sleep drive is adenosine. Adenosine is a naturally occurring chemical compound in the body that is a byproduct of the breakdown of ATP (adenosine triphosphate), the primary energy source for cells. Adenosine levels increase in the brain as wakefulness persists, and its buildup eventually signals to the brain that it is time to sleep.

Adenosine acts as an inhibitor of wake-promoting neurons in the brain, leading to drowsiness and a desire to sleep. Caffeine, which is a widely used stimulant, works by blocking the effects of adenosine in the brain, thereby promoting wakefulness. The homeostatic sleep drive, which is the body's natural tendency to regulate sleep-wake cycles, is closely linked to adenosine levels. The accumulation of adenosine during wakefulness drives the need for sleep, and the reduction of adenosine during sleep prepares the body for wakefulness. In summary, adenosine plays a critical role in the regulation of sleep-wake cycles, and its levels in the brain are closely linked to the homeostatic sleep drive.

The wavelength of the photon required to excite an electron from n=2 to n=6 in a He⁺ ion is approximately 0.485 nm.

The energy of a photon required to excite an electron from n=2 to n=6 can be calculated using the Rydberg equation;

1/λ = R(1/n₁² - 1/n₂²)

where λ is the wavelength of the photon, R is the Rydberg constant (1.0974 x 10⁷ m⁻¹), n₁ is the initial energy level (2), and n₂ is the final energy level (6).

Plugging in the values, we get;

1/λ = 1.0974 x 10⁷ m⁻¹ (1/2² - 1/6²)

1/λ = 1.0974 x 10⁷ m⁻¹ (0.1875)

1/λ = 2060.25 nm⁻¹

Taking the reciprocal of both sides gives us the wavelength;

λ = 1/2060.25 nm⁻¹

λ ≈ 0.485 nm

Therefore, the wavelength of the photon is  0.485 nm.

Answer:

No of protons = 15

Explanation:

Given that,

Atomic number = 15

Mass number = 31

We need to find the no of protons in the atom.

We know that,

No of protons = Atomic no of the atom

No of protons = 15

Hence, there are 15 protons in the atoms.

The percent yield of H₂O, if 87.0 g of H₂O is produced by combining 95.0 g of O₂ and 11.0 g of H₂ is 87.87%.

Mass of any substance will be calculated by using their moles as:

n = W/M, where

W = given or required mass

M = molar mass

Moles of 95g of Oxygen (O₂) = 95g / 32g/mol = 2.96 moles

Moles of 11g of hydrogen (H₂) = 11g / 2g/mol = 5.5 moles

Given chemical reaction is:
2H₂ + O₂ → 2H₂O

From the stoichiometry of the reaction, it is clear that:

1 moles of O₂ = reacts with 2 moles of H₂

2.96 moles of O₂ = reacts with 2×2.96=5.92 moles of H₂

Here hydrogen is the limiting reagent as it has lower moles and formation of water depends on this only.

2 moles of H₂ = produces 2 moles of water

5.5 moles of H₂ = produces 5.5 moles of water

Mass of 5.5 moles of water will be calculated as:

W = (5.5mol)(18g/mol) = 99g

Given theoretical yield of water = 87g

% yield of water will be calculated as:
% yield = (87 / 99)×100 = 87.87%

Explanation:

The amount of 0.054 M Acetic Acid solution are required to completely react 100.00 g of Sodium Carbonate is 34.981 mL.

The balanced chemical reaction for the reaction of acetic acid with sodium carbonate is:

2CH3COOH + Na2CO3 → 2CH3COONa + H2O + CO2

To find the volume of 0.054 M acetic acid required to react with 100.00 g of sodium carbonate, we need to follow these steps:

1: Convert the mass of Na2CO3 to moles.

Molar mass of Na2CO3 = 2(23) + 12 + 3(16) = 106 g/mol

Number of moles of Na2CO3 = Mass / Molar mass = 100 / 106 = 0.9434 moles

2: Determine the limiting reactant

In this case, we can see from the balanced chemical equation that the stoichiometric ratio of acetic acid to sodium carbonate is 2:1. This means that 2 moles of acetic acid react with 1 mole of sodium carbonate.

Hence, the number of moles of acetic acid required to react with the given amount of sodium carbonate is:

2 x 0.9434 = 1.8868 moles

3: Calculate the volume of acetic acid required

Using the equation: Molarity = Moles / Volume

Rearranging for volume: Volume = Moles / Molarity

Substituting the values:

Volume of acetic acid = 1.8868 / 0.054Volume of acetic acid = 34.981 mL (rounded to 3 decimal places)

Therefore, 34.981 mL of a 0.054 M acetic acid solution is required to completely react 100.00 g of sodium carbonate.

The scenario that best exemplifies the way a signal is passed down an axon coated with myelin sheath is saltatory conduction, where the signal jumps from one node of Ranvier to the next, allowing for faster transmission.

Saltatory conduction is the process by which a signal travels down an axon that is coated with a myelin sheath. The myelin sheath acts as an insulator, preventing the signal from dissipating and allowing it to travel faster and more efficiently. When the signal reaches a node of Ranvier, it depolarizes the membrane and triggers the opening of voltage-gated ion channels.

This causes the signal to quickly jump to the next node of Ranvier, bypassing the areas covered by the myelin sheath. This process continues along the length of the axon until the signal reaches the end. Saltatory conduction reduces the energy consumption of the neuron and speeds up signal transmission. It is particularly important for long axons, where it allows for rapid communication in the nervous system.

You know the number of moles of Mg that react: 6 moles.

You don't know (yet) how many moles of Mg₃N₂ are produced when 6 moles of Mg react.

The coefficients of each substance in the chemical equation tells us the molar ratio between the substances. The coefficient of Mg is 3, and the coefficient of Mg₃N₂ is 1 (coefficients of 1 are implied and omitted). So, for every 3 moles of Mg that react, 1 mole of Mg₃N₂ is produced.

We can use the proportion set up in the image to calculate the number of moles of Mg₃N₂ produced. In the first fraction, the green-boxed numerator should be our known number of moles of Mg, that is, 6 moles Mg. In the second fraction, we insert our molar ratio. Since we want the product of these two fractions to have the units "moles Mg₃N₂," the numerator in the second fraction should be 1 mole Mg₃N₂ and the denominator should be 3 moles Mg.

Our setup should look like this:

\(\frac{\textrm{6 moles Mg}}{1} \times \frac{\textrm{1 mole }\mathrm{Mg_3N_2}}{{\textrm{3 moles Mg}}} = \textrm{2 moles }\mathrm{Mg_3N_2}.\)
