Answer:

500 hits

Explanation:

If 20 hits equal 1 web 1 futz equal 2 geese 10 webs equal to 1 futz How many hits are equal to 5 geese?

Solution:

Given that:

20 hits = 1 web, 1 futz = 2 geese; 10 webs = 1 futz

10 webs = 1 futz; hence:

1 web = 1 web * 1 futz / 10 webs = 0.1 futz

1 web = 0.1 futz

1 futz = 2 geese; hence:

0.1 futz = 0.1 futz * 2 geese / 1 futz

0.1 futz = 0.2 geese

Therefore, 1 web = 0.1 futz = 0.2 geese

1 web = 0.2 geese

This means that 20 hits = 1 web = 0.2 geese

20 hits = 0.2 geese

5 geese = 5 geese * 20 hits / 0.2 geese

5 geese = 500 hits

Acetic acid will neutralize the addition of a strong base in an acetic acid/acetate buffer system.

In an acetic acid/acetate buffer system, the main purpose is to resist changes in pH when small amounts of acid or base are added. When a strong base is added, it increases the concentration of hydroxide ions (OH-) in the solution, which can shift the pH towards the basic side.

To neutralize the added strong base and maintain the buffer system, acetic acid (CH3COOH) acts as the main keyword. Acetic acid, being a weak acid, can react with the hydroxide ions (OH-) to form water (H2O) and acetate ions (CH3COO-). This reaction helps in counteracting the increase in hydroxide ions, thereby stabilizing the pH of the buffer system.

Water (H2O), acetate ions (CH3COO-), and hydronium ions (H3O+) are already present in the buffer system and do not actively neutralize the strong base. It is the addition of acetic acid that replenishes the buffer's acid component and maintains its pH buffering capacity.

During condensation reaction, two molecules combine to form a single molecule with the loss of a small molecule; in dehydration reaction, this lost molecule is water.

The reaction is a small molecule formed from the atoms removed from a single reactant molecule this reaction is knowing as condensation reaction.

Essentially, this is the reverse process of vaporization. In order for water vapor to undergo the process of condensation, which is the change from a gaseous state to a liquid state, it is necessary for a reduction in its temperature to occur until it reaches the dew point or an increase in the pressure to which it is subjected.

In this case the condensation reaction are when two molecules combine to form a single molecule with the loss of a small molecule, in dehydration reaction, this lost molecule is water.

Explanation:

An asymmetrical molecule is a molecule that has non-superimposable mirror images. In other words, the molecule cannot be superimposed on its own mirror image.

One way to represent an asymmetrical molecule is with the formula R-L, where R and L represent different groups attached to a central carbon atom. This formula indicates that the molecule has a chiral carbon, which is a carbon atom that is bonded to four different groups. Because the groups attached to the carbon atom are different, the molecule is asymmetrical.

Another way to represent an asymmetrical molecule is with the formula (R,R)-(S,S), where R and S represent different groups attached to a central carbon atom. This formula indicates that the molecule has two chiral carbons, each of which is bonded to two R groups and two S groups. Because the groups attached to the carbons are different, the molecule is asymmetrical.

Overall, the exact formula for an asymmetrical molecule will depend on the specific groups attached to the central carbon atom(s) and the arrangement of those groups.

The molarity of the original HF solution is 1.00 M.  Moles of NaOH = Molarity of NaOH x Volume of NaOH used (in L)

We are given the molarity of NaOH (0.1500 M) and the volume of NaOH used (13.51 ml or 0.01351 L), so we can calculate the number of moles of NaOH used:

moles of NaOH = 0.1500 M x 0.01351 L = 0.0020275 moles

Next, we can use the balanced chemical equation for the reaction between NaOH and HF to determine the number of moles of HF that were present in the 20.00 ml sample:

NaOH + HF → NaF + H₂O

From the equation, we can see that 1 mole of NaOH reacts with 1 mole of HF. Therefore, the number of moles of HF in the 20.00 ml sample is also 0.0020275 moles.

Now we need to calculate the molarity of the original HF solution. We know that the 10.00 ml sample was diluted to 500.00 ml, which means the dilution factor is 500.00 ml / 10.00 ml = 50. Therefore, the concentration of the diluted solution is 1/50th (or 0.02) of the concentration of the original solution.

Let x be the molarity of the original HF solution. Then, we can use the formula for dilution to set up an equation:

M₁V₁ = M₂V₂

where M1 is the molarity of the original solution (x), V₁ is the volume of the original solution (10.00 ml), M₂ is the molarity of the diluted solution (0.02), and V₂ is the final volume of the diluted solution (500.00 ml).

Plugging in the values and solving for x, we get:

x = M₁ = (M₂V₂) / V1 = (0.02 x 500.00 ml) / 10.00 ml = 1.00 M

Therefore, the molarity of the original HF solution is 1.00 M.

In a crucible, a sample of pure iron is covered with an excessive amount of sulfuric acid powder. The extra sulphur was heated off by heating the mixture to a temperature wherein a reaction took place.

To calculate the mass of iron and sulfur in the compound, we need to consider the changes in mass during the reaction.

First, we determine the mass of iron by subtracting the mass of the crucible and lid (19.746 g) from the mass of iron, crucible, and lid (20.422 g).

This gives us 0.676 g of iron.

Next, we calculate the mass of sulfur by subtracting the mass of the compound, crucible, and lid (21.195 g) from the mass of the crucible and lid (19.746 g).

This gives us 1.449 g of sulfur.

To determine the moles of iron and sulfur, we need to divide their masses by their respective molar masses.

The molar mass of iron is 55.845 g/mol, so the moles of iron can be calculated by dividing 0.676 g by 55.845 g/mol, resulting in approximately 0.0121 mol of iron.

Similarly, the molar mass of sulfur is 32.06 g/mol, so the moles of sulfur can be calculated by dividing 1.449 g by 32.06 g/mol, giving us approximately 0.0451 mol of sulfur.

The pseudoformula for the compound indicates the ratio of iron to sulfur. From the moles obtained, the ratio of iron to sulfur is approximately 1:3.

Therefore, FeS3 functions as the compound's pseudoformula.

We need to identify the most basic whole-number ratio of atoms for us to arrive at the empirical formula.

Energy transfer by direct contact is conduction.

Explanation:

Conduction is the process of heat or electricity being transferred through a solid material by the movement of molecules. When two objects are in direct contact with each other, heat can be transferred from one object to the other through conduction. This is because the molecules in the hotter object have more energy, and they transfer some of their energy to the molecules in the cooler object through collisions and interactions.

Energy transfer as electromagnetic waves, energy transfer by currents of moving liquid or gas, and energy transfer from a reaction system to its surroundings are all examples of different methods of energy transfer, but they are not conduction.

If you have any question let me know

Energy transfer by direct contact is conduction. Therefore, option B is correct.

Conduction is a mode of energy transfer that occurs through direct contact between objects or substances. When objects or substances with different temperatures come into contact, the hotter object transfers thermal energy to the colder object through conduction.

Conduction refers to the transfer of heat or thermal energy from a region of higher temperature to a region of lower temperature. This transfer occurs when the atoms or molecules of the hotter object collide with those of the colder object, transferring kinetic energy and increasing the motion of the colder object's particles.

As a result, the temperature of the colder object increases, while the temperature of the hotter object decreases until both reach thermal equilibrium.

In quantum mechanics, the angular momentum quantum number "l" defines the shape of the atomic orbital. The l value is an integer ranging from 0 to (n-1) where n is the principal quantum number.

Therefore, for an electron in the L(n=2) shell of an atom, the possible values of the angular momentum quantum number l would range from 0 to 1, since n=2.

This is because the L shell is the second shell, which has n=2. Therefore, it can have subshells with l=0 and l=1, also known as the s and p subshells respectively.

The angular momentum quantum number also has an effect on the energy of the electron, with higher l values having higher energy.

Thus, the possible values of the angular momentum quantum number l for an electron in the L(n=2) shell of an atom are l=0 and l=1.

The specific composition of oil-based paint can vary depending on the brand and formulation.

Oil-based paint typically consists of three main components: pigments, binders, and solvents. The pigments provide the color and opacity to the paint, while the binders are responsible for holding the pigment particles together and adhering them to the painted surface. The solvents help to adjust the paint's consistency and facilitate its application.

The binder in oil-based paint is commonly a natural oil, such as linseed oil or tung oil. These oils are composed of fatty acid molecules, which contain a long carbon chain with a carboxyl group (-COOH) at one end. The carboxyl group can react with oxygen in a process called oxidation, forming a cross-linked network of molecules that harden over time, creating a durable paint film.

The solvents in oil-based paint are typically organic compounds, such as mineral spirits or turpentine. These solvents dissolve the binder and pigments, making the paint flowable and easy to apply. As the solvent evaporates, the paint gradually dries and the binder undergoes the oxidation process, resulting in the formation of a solid paint film.
