The half-life of the radioactive goo can be determined by using the formula mentioned above. In order to determine the half-life of the radioactive goo, we can use the following formula:

t = (t₁/2) * log₂(N₀/N)

Where:

- t is the half-life we want to find.

- t₁/2 is the known half-life (in this case, it's the time it takes for the substance to decay to half its initial amount).

- N₀ is the initial amount of the substance.

- N is the amount of the substance remaining after the given time.

From the problem statement, we know that the initial amount N₀ is 236 grams and the amount remaining after 210 minutes, N, is 14.75 grams. We can now plug these values into the formula:

210 = (t₁/2) * log₂(236/14.75)

To solve for t₁/2, we can rearrange the equation:

t₁/2 = 210 / log₂(236/14.75)

The value of t₁/2 can be calculated using a calculator or software. Once we have the half-life, we can use it to find the amount of goo remaining after 5 minutes using the general formula for radioactive decay:

N(t) = N₀ * (1/2)^(t/t₁/2)

For t = 5 minutes, N₀ = 236 grams, and t₁/2 is the calculated value, we can substitute these values into the formula to find the remaining amount of goo after 5 minutes. Given the initial amount and the amount remaining after a certain time, we can solve for the half-life. Once we have the half-life, we can use the general formula for radioactive decay to find the remaining amount of goo after any given time.

The property that cannot be used to determine whether the two powders are the same substance is (d) dissolves in water.

The reason is that the ability to dissolve in water is not a unique property that can be used to identify a specific substance. Many different substances can dissolve in water, and the fact that both powders can dissolve in water does not necessarily mean they are the same substance.

On the other hand, properties such as mass, density, and the ability to burn in air can provide more specific information about the nature of the substance. Mass is a fundamental property that can be measured accurately, and if the two powders have the same mass, it suggests they may be the same substance. Density is a derived property that can also be measured and compared, providing information about the compactness of the material. The ability to burn in air indicates a chemical reactivity that can be used to distinguish between different substances.

Therefore, while properties like mass, density, and burning in air can provide valuable information for identifying substances, the property of dissolving in water alone is not sufficient to determine whether the two powders are the same substance.

The correct statement among the given options is:

A conjugate base is the species that remains after a base has given up a proton.

In the context of acid-base chemistry, a conjugate base is the species that remains after a base donates or gives up a proton (H+). When a base loses a proton, it transforms into its conjugate base, which is the species with one less proton compared to the original base.

For example, in the reaction between the base ammonia (NH3) and an acid, NH3 acts as a base and accepts a proton (H+), resulting in the formation of its conjugate acid, ammonium ion (NH4+). NH3 is the base, and NH4+ is its conjugate acid.

Therefore, the correct statement is that a conjugate base is the species that remains after a base has given up a proton.

When deciding whether to produce in the long run, the firm should consider whether average revenue is greater than average total cost.

In the long run, a firm's decision to produce is based on its ability to cover all costs and generate a profit. Average revenue represents the per-unit revenue earned by the firm, which is calculated by dividing total revenue by the quantity of output. Average total cost, on the other hand, represents the per-unit cost incurred by the firm, calculated by dividing total cost by the quantity of output.

If average revenue is greater than average total cost, it means that the firm is generating more revenue per unit than it is incurring in costs. This suggests that the firm is profitable and should continue producing in the long run. However, if average revenue is less than average total cost, it means that the firm is not covering its costs with the revenue generated per unit. In this case, the firm may need to reassess its production decisions and consider adjustments such as reducing costs or increasing prices to improve profitability.

To find the concentration of Fe(NO3)3 after mixing, we need to calculate the total volume of the solution and the number of moles of Fe(NO3)3 present. The total volume of the solution is the sum of the volumes of the individual solutions: 5.0 mL + 3.0 mL + 2.0 mL = 10.0 mL.

First, let's calculate the moles of Fe(NO3)3:

moles of Fe(NO3)3 = volume of Fe(NO3)3 solution × concentration of Fe(NO3)3

                  = 5.0 mL × 0.0020 M

                  = 0.01 mmol (millimoles)

Since the volume is given in milliliters and the concentration is in moles per liter, we converted the volume to liters by dividing by 1000.

Now, let's calculate the final concentration of Fe(NO3)3:

concentration of Fe(NO3)3 = moles of Fe(NO3)3 / total volume of the solution

                         = 0.01 mmol / 10.0 mL

                         = 0.0010 M

An endothermic reaction feels cold to the touch because the reaction absorbs heat from its surroundings. When you touch the vessel in which the reaction occurs, you, as part of the surroundings, transfer heat to the system, which makes you feel cold.

The heat absorbed by the reaction does not increase its temperature but rather becomes potential energy stored in chemical bonds. In an endothermic reaction, energy is required to break the existing bonds in the reactants, and this energy is absorbed from the surroundings. As a result, the surroundings lose heat, leading to a decrease in temperature. When you touch the vessel, heat is transferred from your body to the system, further contributing to the cooling effect. However, this heat does not raise the temperature of the reaction itself but instead becomes potential energy, stored in the newly formed bonds of the products. Therefore, the sensation of coldness when touching an endothermic reaction vessel is due to the heat transfer from your body, which is utilized to fuel the energy requirements of the reaction, rather than directly increasing the reaction's temperature.

In the given reaction, benzaldehyde and potassium cyanide are the reactants. To determine the limiting reagent, we need to compare the number of moles of each reactant and identify the one that is completely consumed.

To find the limiting reagent, we can use the molar ratio between benzaldehyde and benzoin.

First, we calculate the number of moles of benzaldehyde:

moles of benzaldehyde = (volume of benzaldehyde in mL) x (density of benzaldehyde in g/mL) / (molecular weight of benzaldehyde in g/mol)

moles of benzaldehyde = (24 mL) x (1.04 g/mL) / (106 g/mol)

Next, we calculate the number of moles of potassium cyanide:

moles of potassium cyanide = (mass of potassium cyanide in g) / (molecular weight of potassium cyanide in g/mol)

moles of potassium cyanide = 1 g / 65.12 g/mol

Now, we compare the moles of benzaldehyde and potassium cyanide to determine the limiting reagent. The reactant that produces fewer moles of benzoin is the limiting reagent.

Finally, we can calculate the number of moles of benzoin that can be produced from each reactant by using the stoichiometric ratio of the balanced equation. The limiting reagent will be the one that produces the smaller amount of benzoin.

The percent by mass of methyl acetate in the boiling solution is 76.9%.

Given that the vapor pressure of methyl acetate at 95.7 °C is 2419 torr and the vapor pressure of water at 95.7 °C is 651 torr;

P(CH₃COOCH₃) = X(CH₃COOCH₃) * P°(CH₃COOCH₃)

where

P(CH₃COOCH₃) is the partial pressure of methyl acetate, X(CH₃COOCH₃) is the mole fraction of methyl acetate, and

P°(CH₃COOCH₃) is the vapor pressure of pure methyl acetate.

P(CH₃COOCH₃) = 2419 torr

P°(CH₃COOCH₃) = 2419 torr

P(H₂O) = 651 torr

Using Raoult's law:

X(CH3COOCH3) = P(CH₃COOCH₃) / (P(CH₃COOCH₃) + P(H₂O))

X(CH₃COOCH₃) = 2419 torr / (2419 torr + 651 torr)

X(CH₃COOCH₃) = 0.787

mass of methyl acetate / mass of water = x / (1 - x)

mass of methyl acetate/mass of water = 0.787 / (1 - 0.787)

mass of methyl acetate/mass of water = 3.59

Using the density of methyl acetate (0.93 g/mL), we can convert the mass ratio to a volume ratio:

volume of methyl acetate / volume of water = (3.59 * (0.93 g/mL)) / (1 g/mL)

the volume of methyl acetate/volume of water = 3.33

The volume ratio of methyl acetate to water is 3.33. Since the solution boils at 95.7 °C, we can assume that the volume ratio is the same as the mole ratio:

moles of methyl acetate/moles of water = 3.33

z = moles of methyl acetate / (moles of methyl acetate + moles of water)

z = 3.33 / (3.33 + 1)

The equilibrium constant (K) for the given reaction, N2(g) + 3 H2(g) ↔ 2 NH3(g), is extremely small, indicating that very little NH3 is produced. This is due to the reverse reaction having a lower activation energy than the forward reaction.

In this **chemical reaction**, nitrogen (N2) and hydrogen (H2) gases combine to form ammonia (NH3) gas. The **equilibrium constant (K)** is a measure of the ratio of product concentration to reactant concentration at equilibrium. When K is very small, it means that the concentration of reactants is much higher than that of products, suggesting that the reaction does not favor the formation of NH3. The **activation energy** is the minimum amount of energy required for a reaction to proceed. Since the reverse reaction (breaking down NH3 into N2 and H2) has a lower activation energy than the forward reaction (forming NH3 from N2 and H2), it is easier for the reaction to proceed in the reverse direction, further limiting the amount of NH3 formed.
