b) equilibrium shifts towards the right hand side.
c)equilibrium shifts towards the left hand side
d) addition of argon has no effect on the equilibrium position
e) equilibrium position shifts towards the left hand side
f) equilibrium position is shifted towards the right hand side
g) addition of a catalyst has no effect on the equilibrium position
Explanation:
Given the equation;
3N2H4(g)⇄ 4NH3 (g) + N2 (g)
Adding N2
The addition of N2 will increase the concentration of N2 in the system thereby shifting the equilibrium position to the left in accordance with Le Chatelier's principle.
Removing N2
The removal of N2 drives the forward reaction and the equilibrium shifts towards the right yielding more N2 in accordance with Le Chateliers principle.
Add NH3
The addition of NH3 will shift the equilibrium position towards the left hand side according to Le Chateliers principle.
d) addition of argon has no effect on the equilibrium position.
e) increasing the temperature
Since the reaction is exothermic, increasing the temperature favours the reverse reaction and the equilibrium position his shifted towards the left hand side.
f) Decrease in volume;
Decreasing the volume favours the forward reaction hence the equilibrium position is shifted towards the right.
g) addition of a catalyst has no effect on the equilibrium position.

moles of each product that would form as a result of the decomposition of aspirin
Answers
The decomposition of aspirin (acetylsalicylic acid,\(C_{9} H_{8} O_{4}\)) can occur through the hydrolysis reaction, resulting in the formation of acetic acid (\(CH_{3} COOH\)) and salicylic acid (\(C_{7} H_{6}O_{3}\)).
The decomposition of aspirin (acetylsalicylic acid, \(C_{9} H_{8} O_{4}\)) can occur through the hydrolysis reaction, resulting in the formation of acetic acid (\(CH_{3} COOH\)) and salicylic acid (\(C_{7} H_{6}O_{3}\)). To determine the moles of each product formed, we need to consider the balanced chemical equation for the reaction:
\(C_{9} H_{8} O_{4} = > C_{7} H_{6}O_{3} +CH_{3} COOH\)
From the equation, we can see that for every 1 mole of aspirin, 1 mole of salicylic acid and 1 mole of acetic acid are produced.
Therefore, the moles of salicylic acid and acetic acid formed will be equal to the number of moles of aspirin that decomposes. If we know the amount of aspirin in moles, we can directly calculate the moles of each product based on stoichiometry.

Answers
Answer: 3
Explanation:
3) both electrolytic cells and voltaic cells
The statement, that describes reduction occurs at the cathode is "both electrolytic cells and voltaic cells."
What is a reduction?The gain of electrons is referred to as reduction. The species that is being oxidised is also known as the reducing agent or reductant, whereas the species that is being reduced is known as the oxidising agent or oxidant.
Reduction takes place at the cathode electrode whereas oxidation occurs at the anode in both galvanic and electrolytic cells, and electrons travel from the anode to the cathode.
Electrons must move toward the location of reduction since reduction is the addition of electrons. The negative charge is on the cathode of an electrolytic cell, while the positive charge is on the anode.
Hence, the correct answer is 3.

Based on the given bright-line spectra and the observed wavelengths in the mixture's spectrum, the elements G and J are the ones present in the mixture.
From the given bright-line spectra and the spectrum of the mixture, we can determine the elements present in the mixture by comparing the specific wavelengths observed. Examining the bright-line spectra, we can identify that G has a distinct wavelength at 650 nm, J at 600 nm, L at 550 nm, and M at 500 nm.
Looking at the spectrum of the mixture, we can observe two prominent wavelengths, 650 nm and 600 nm. These correspond to the wavelengths of G and J, respectively. Since the spectrum of the mixture does not exhibit the wavelengths specific to L (550 nm) or M (500 nm), we can conclude that only G and J are present in the mixture.
Therefore, based on the given bright-line spectra and the observed wavelengths in the mixture's spectrum, the elements G and J are the ones present in the mixture.
This analysis relies on the principle that each element has characteristic wavelengths at which they emit light. By comparing the observed wavelengths in the mixture's spectrum with those of the individual elements, we can determine the elements present in the mixture.

287.13 grams of Al₂O₃ were decomposed. Therefore, option A is correct.
What is molar mass ?The term molar mass is defined as the mass in grams of one mole of the compound. A mole of any substance is 6.022 × 10²³ molecules. It is called as Avogadro's number. The molar mass is a bulk property, it is not molecular, property of a substance.
2Al₂O₃ ⇒ 4Al + 3O₂
Thus, 4 mol of Al combine with 3 mol of oxygen to form 2 mol of Al₂O₃.
2 mol of Al corresponds to 2 × 27 = 54g
Thus, the weight of Al used in the reaction is 108 g.
Molar mass of Al₂O₃ is 101.96g/mol.
5.63 moles of Al = 5.63 × 54 / 101.96

2. Show the calculation supporting the claim that atmospheric pressure near sea level corresponds to the pressure exerted by a column of mercury that is about 760 mm high. Considering the density of mercury = 13.6 g/cm³.
Answers
The pressure exerted by a column of mercury that is about 760 mm high corresponds to approximately 0.987 atm.
To calculate the pressure exerted by a column of mercury, we can use the formula:
Pressure = density * gravity * height
Given:
Density of mercury = 13.6 g/cm³
Height of the mercury column = 760 mm = 76 cm
Acceleration due to gravity = 9.8 m/s²
First, we need to convert the height of the mercury column from centimeters to meters:
Height = 76 cm * (1 m / 100 cm) = 0.76 m
Now, we can calculate the pressure:
Pressure = 13.6 g/cm³ * 9.8 m/s² * 0.76 m
To ensure consistent units, we need to convert the density from grams per cubic centimeter (g/cm³) to kilograms per cubic meter (kg/m³):
Density = 13.6 g/cm³ * (1 kg / 1000 g) * (1 cm³ / (1e-6 m³))
Density = 13600 kg/m³
Plugging in the values into the pressure formula:
Pressure = 13600 kg/m³ * 9.8 m/s² * 0.76 m
Pressure = 99992.8 Pa
We can express the pressure in terms of atmospheric pressure:
1 atm = 101325 Pa (approximately)
To compare the pressure with atmospheric pressure, we can convert 99992.8 Pa to atm:
Pressure in atm = 99992.8 Pa / 101325 Pa/atm
Pressure in atm ≈ 0.987 atm
The pressure exerted by a column of mercury that is about 760 mm high corresponds to approximately 0.987 atm. Since atmospheric pressure near sea level is approximately 1 atm, this calculation supports the claim that atmospheric pressure near sea level is equivalent to the pressure exerted by a column of mercury about 760 mm high.

reacted, how much heat is produced (kJ)?
Answers
The amount of heat energy produced when 1 g of hydrogen and 2 g of nitrogen are reacted, is -6.61 KJ
How do i determine the heat energy produced?First, we shall obtain the limiting reactant. Details below:
3H₂ + N₂ -> 2NH₃
Molar mass of N₂ = 28 g/molMass of N₂ from the balanced equation = 1 × 28 = 28 g Molar mass of H₂ = 2 g/molMass of H₂ from the balanced equation = 3 × 2 = 6 gFrom the balanced equation above,
28 g of N₂ reacted with 6 g of H₂
Therefore,
2 g of N₂ will react with = (2 × 6) / 28 = 0.43 g of H₂
We can see that only 0.43 g of H₂ is needed in the reaction.
Thus, the limiting reactant is N₂
Finally, we the amount of heat energy produced. Details below:
3H₂ + N₂ -> 2NH₃ ΔH = -92.6 KJ
Molar mass of N₂ = 28 g/molMass of N₂ from the balanced equation = 1 × 28 = 28 gFrom the balanced equation above,
When 28 grams of N₂ reacted, -92.6 KJ of heat energy were produced.
Therefore,
When 2 grams of N₂ will react to produce = (2 × -92.6) / 28 = -6.61 KJ
Thus the heat energy produced from the reaction is -6.61 KJ
