The reaction of carboxylic acid with alcohols catalysed by conc. H2so4 is called.

The limiting reactant in this reaction is H₂SO₄.

To determine the limiting reactant, we compare the amount of product that can be formed from each reactant. We will calculate the number of moles of Al₂(SO₄)₃ that can be produced from both reactants and compare their values.

Given:

Mass of H₂SO₄ = 25 grams

Molar mass of H₂SO₄ = 98.09 g/mol

Molar ratio between H₂SO₄ and Al₂(SO₄)₃ = 3:1

Number of moles of H₂SO₄ = mass / molar mass

= 25 g / 98.09 g/mol

= 0.255 mol

Number of moles of Al₂(SO₄)₃ formed from H₂SO₄ = 0.255 mol / 3 = 0.085 mol

Given:

Mass of Al(OH)₃ = 23 grams

Molar mass of Al(OH)₃ = 78.00 g/mol

Molar ratio between Al(OH)₃ and Al₂(SO₄)₃ = 2:1

Number of moles of Al(OH)₃ = mass / molar mass

= 23 g / 78.00 g/mol

= 0.295 mol

Number of moles of Al₂(SO₄)₃ formed from Al(OH)₃ = 0.295 mol / 2 = 0.148 mol

Comparing the moles of Al₂(SO₄)₃ formed from each reactant, we find that the H₂SO₄ produces a lower amount (0.085 mol) compared to Al(OH)₃ (0.148 mol). Therefore, the H₂SO₄ is the limiting reactant in this reaction.

To calculate the mass of Al₂(SO₄)₃ produced, we can use the molar mass of Al₂(SO₄)₃:

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

Mass of Al₂(SO₄)₃ = number of moles * molar mass

= 0.085 mol * 342.15 g/mol

≈ 29.1 grams

Therefore, you would be able to produce approximately 29.1 grams of Al₂(SO₄)₃ using 25 grams of H₂SO₄.

When \(CO_{2}\) and \(H_{2} CO_{3}\) are both horizontal lines, the rate of the forward reaction is the same as the rate of the reverse reaction. The reaction is occurring at equilibrium, with no net change in the concentrations of reactants and products over time.

When the concentration of carbon dioxide \(CO_{2}\) and the concentration of carbonic acid \(H_{2} CO_{3}\) are both horizontal lines, it indicates that their concentrations remain constant over time. In such a scenario, the rate of the forward reaction is the same as the rate of the reverse reaction. A horizontal line on a concentration-time graph suggests that the concentrations of the reactants and products are not changing, implying that the reaction has reached equilibrium. At equilibrium, the rate of the forward reaction equals the rate of the reverse reaction. This is a fundamental principle of chemical equilibrium, described by the principle of microscopic reversibility.

The SL-3 components of the M240B medium machine gun are used for barrel replacement and maintenance.

The SL-3 components of the M240B consist of a spare barrel and a barrel bag. The spare barrel is an essential component for sustained firing and allows for the replacement of a hot or worn-out barrel during extended periods of continuous use. When the barrel becomes overheated, it can negatively impact the weapon's accuracy and potentially cause malfunctions. The spare barrel is designed to be quickly swapped with the hot barrel to ensure optimal performance and prevent damage to the weapon.

The barrel bag is used to safely store the hot or dirty barrel after it has been replaced. It serves as a protective cover to prevent accidental contact and potential burns while the barrel is still hot. Additionally, the bag helps contain any carbon or residue that may be present on the barrel, preventing it from spreading and contaminating other equipment or personnel. The barrel bag is an essential part of the maintenance process, ensuring safe handling and transportation of the replaced barrel until it can be properly cleaned and inspected.

The density of gold is approximately 19.3 grams per cubic centimeter (g/cm³). If the density of the rock closely matches that of gold, it could indicate that the rock contains gold or a gold-like material.

Weigh the rock: Start by weighing the rock using a scale that can measure its mass accurately. Record the mass in grams (g). Make sure to handle the rock carefully to avoid any damage. Determine the volume: There are a few methods you can use to determine the volume of the rock. One common method is water displacement.

Fill a graduated cylinder with water, noting the initial volume. Carefully lower the rock into the water, making sure no air bubbles are trapped. Measure the volume of the water displaced by the rock. The difference between the final and initial volume gives you the volume of the rock in milliliters (ml).

Calculate the density: Once you have the mass and volume of the rock, you can calculate its density using the formula:

Density = Mass / Volume

Ensure that the mass is in grams and the volume is in milliliters.

Compare to known densities: Finally, compare the density value you calculated to the known densities of materials. The density of gold is approximately 19.3 grams per cubic centimeter (g/cm³). If the density of the rock closely matches that of gold, it could indicate that the rock contains gold or a gold-like material.

However, further testing and analysis would be needed to confirm its composition. It's important to note that the appearance of a rock alone cannot definitively determine its composition or density.

In organic chemistry, an alkyne is defined as the unsaturated hydrocarbon containing at least one carbon-carbon triple bond. The alkynes are unsaturated hydrocarbons and their general formula is CₙH₂ₙ₋₂ and the triple bond is known as the acetylene bond.

Many alkynes are found in nature. Ethyne is the first member of the alkyne family in which two carbon atoms are connected by a triple bond. Almost all alkynes are also found to be hydrophobic in nature.

Alkynes show three types of isomerism like chain isomerism, position isomerism and functional isomerism. The triple bond present in the alkynes is its functional group.

The direct energy source that drives ATP synthesis during respiratory oxidative phosphorylation is a difference of concentration on the opposite sides of the inner mitochondrial membrane.

The ETS in the mitochondria is used for the transport of electrons and hydronium ions from inner mitochondrial membrane to the inter membrane matrix of mitochondria. Due to this the concentration of hydronium ions increases in the intermembrane matrix. The ATP synthase complex which is present in the inner membrane of the mitochondria are used for the synthesis of ATP. The complex is used to transport hydronium ions from the intermembrane matrix down its concentration gradient For every 2 hydronium ions transported through the complex one molecule of ATP is generated. Therefore the transport of the H+ ions due the difference in the concentration provides direct energy for the formation of ATP.

Answer:

a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.

The volume of gas in the tank is determined as 1.78 L.

The volume of gas in the tank is calculated by applying idle gas law as follows;

PV = nRT

where;

n = reacting mass / molar mass

n = (300 g) / (3 x 16 g)

n = (300 g) / (48 g/mol)

n = 6.25 moles

The volume of the gas is calculated as follows;

V = nRT/P

V = (6.25 x 8.314 x 214.25)/(6250)

V = 1.78 L

Thus, the volume of ideal gas increases with increase in temperature.

Fe (s) + H₂O (g) → Fe₃O₄ (s) + H₂ (g)

Now, we need to balance the equation. On the right-hand side, we have 3 Fe, 4 O and 2 H. Similarly on the left-hand side there are 1 Fe, 1 O and 2 H.

To balance the equation, we add 3 to Fe, 4 to H₂0 and 4 to H₂.
