The concentration of the diluted solution is 1.11M , using formula M1V1=M2V2 (whereM = molarity , V = volume).

The formula M1V1=M2V2 is the most widely used.

You must ensure that M stands for Molarity and V for Volume in Liters in this formula. You must divide 29.0 mL by 1,000 in order to convert this problem's mL to L units (mL =.0290 L).

M1 is the specified molarity (7.71M), and V1 is the specified molarity's volume (.0290 L).

The final molarity M2 is what we are looking for, and the final volume V2 equals 1000 L. (remember to convert the 200.0 mL to L)

Fill in the formula with your numbers.

(X) × (0.2000 L) = (7.71M) × (0.0290 L)

(7.71M) × (0.0290 L) / (0.2000 L) = (X)

1.11M = X

Given that we maintained the same number of moles in the solution, this makes sense.

Answer:

Intermolecular bonds become weaker

Melting

Temperature increases

Molecules vibrate faster

Explanation:

In the solid phase, intermolecular forces are found to be strongest. However, as the temperature is increased, the molecules of the solid begin to vibrate faster and intermolecular forces between them begin to weaken.

As intermolecular forces of a substance become weaker, the substance melts. The molecules in the liquid state possesses greater kinetic energy than the molecules in the solid state.

Hence the the answer above.

The partial pressure of the hydrogen gas collected in this way is 710 mmHg. When collecting a gas over water, the total pressure of the system includes the vapor pressure of water at that temperature

When collecting a gas over water, the total pressure of the system is the sum of the partial pressure of the gas and the vapor pressure of water at that temperature. In this case, the total pressure is given as 742 mmHg, and the vapor pressure of water at 30°C is 31.8 mmHg.

To find the partial pressure of the hydrogen gas, we need to subtract the vapor pressure of water from the total pressure. Therefore, the partial pressure of the hydrogen gas can be calculated as:

Partial pressure of hydrogen gas = Total pressure - Vapor pressure of water

Partial pressure of hydrogen gas = 742 mmHg - 31.8 mmHg

Partial pressure of hydrogen gas = 710 mmHg

In this chemical reaction, the collected hydrogen gas exerts a partial pressure of 710 mmHg.

The correct choice is A) −5Δ[Br−]/Δt. The rate expressed as Δ[Br2]/Δt is proportional to -5 times the rate of change of Br−.

In the given reaction 5Br−(aq) + BrO3−(aq) + 6H+(aq) → 3Br2(aq) + 3H2O(aq), the stoichiometric coefficients provide information about the relationship between the reactants and products. To determine the rate expressed as Δ[Br2]/Δt, we need to compare it with the rate of change of the other species.

Based on the balanced equation, for every 5 moles of Br− consumed, 3 moles of Br2 are produced. Therefore, the rate of change of Br−, Δ[Br−]/Δt, is related to the rate of change of Br2, Δ[Br2]/Δt, by a factor of -5/3.

Bismuth will be more volatile at room temperature because it has a lower boiling point than germanium. Germanium is predicted to have the larger surface tension at its melting point. The atmospheric pressure at the altitude of the camp is approximately 0.641 atm.

Volatility refers to a substance's ability to vaporize or evaporate. Bismuth has a lower boiling point (1560 °C) compared to germanium (2830 °C), which means that it requires less energy to convert bismuth into a gas. As a result, bismuth will be more volatile at room temperature than germanium. Surface tension refers to the attractive force between the molecules at the surface of a liquid. At the melting point, the intermolecular forces between the molecules are weakened, which results in a decrease in surface tension. However, germanium has a higher boiling point (2830 °C) compared to bismuth (1560 °C), which means that germanium has stronger intermolecular forces between its molecules. As a result, germanium is predicted to have a higher surface tension at its melting point compared to bismuth.

Atmospheric pressure estimation for:
1. Identify the given boiling point of water at the camp: 88 °C.
2. Use the provided table to find the corresponding vapor pressure at 88 °C: P(atm) = 0.666 atm.

The animal bone is approximately 19,028 years old based on the 40% loss of carbon-14.

To determine the age of an animal bone based on the percentage of carbon-14 remaining, we can use the concept of half-life. The half-life of carbon-14 is approximately 5,750 years, which means that after this time, half of the carbon-14 originally present will have decayed.

If the bone has lost 40% of its carbon-14, it means that only 60% of the original carbon-14 remains. We can calculate the number of half-lives that have passed to reach this percentage.

Let's assume the original amount of carbon-14 in the bone was 100 units. After one half-life, 50 units of carbon-14 would remain (50% of the original amount). After two half-lives, 25 units would remain (50% of 50 units). Similarly, after three half-lives, 12.5 units would remain (50% of 25 units).

To find out how many half-lives it took to reach 60%, we can set up the following equation:

12.5 units (remaining amount) = 100 units (original amount) * (1/2) ^ n (number of half-lives)

Solving for n:

12.5 = 100 * (1/2) ^ n

Dividing both sides by 100:

0.125 = (1/2) ^ n

Taking the logarithm of both sides:

log(0.125) = log[(1/2) ^ n]

n * log(1/2) = log(0.125)

n = log(0.125) / log(1/2)

Using a calculator, we can find:

n ≈ 3.3219

Therefore, approximately 3.3219 half-lives have passed.

Since each half-life is approximately 5,750 years, we can calculate the age of the bone:

Age = Number of half-lives * Half-life duration

Age = 3.3219 * 5,750 years

Age ≈ 19,028 years

Thus, the animal bone is approximately 19,028 years old based on the 40% loss of carbon-14.

Answer: When you add an electron to zinc, it needs some extra energy. This is because zinc atoms naturally don't like having an extra electron. The extra electron and the electrons already present in zinc repel each other due to their negative charges. So, you have to give some energy to the zinc atom to overcome this repulsion and make it accept the additional electron. Basically, energy input is required to make zinc accept an extra electron because the electron doesn't fit easily and needs some force to be added.

Acceleration, \(a=55.88\ m/s^2\)

Explanation:

It is given that, A top fuel dragster is designed to go from 0 to 100 miles per hour in a mere 0.8.

Initial velocity, u = 0

Final velocity, v = 100 mph

1 mph = 0.44704 m/s

100 mph = 44.704 m/s

Time, t = 0.8 s

We need to find its acceleration. Rate of change of velocity equals acceleration.

\(a=\dfrac{v-u}{t}\\\\a=\dfrac{44.704-0}{0.8}\\\\a=55.88\ m/s^2\)

So, the acceleration is \(55.88\ m/s^2\)

On the basic of Newton's third law, which states that every action has an equal and opposite reaction. So, normal force, Fₚ and Fₛ are equal in magnitude and opposite in direction, so that we need to determine Fₛ in order to determine what the scale reads.

Because both components are easily deactivated by the transfer of a proton from the acid to the amine, and because the hydroxy unit on the carbonyl of the acid is a relatively poor leaving group, amines are typically not accessible by the direct condensation of amines with carboxylic acids.

However, it is frequently surprisingly easy to create five- and six-membered rings provided that additional elements may be utilized to aid in condensation.

By merely sublimating the amino acid at 80 °C, Kirby's team, for instance, showed how to create the "most twisted amide," based on the adamantane structure.

Surprisingly, despite the amide being at room temperature and pH 4, the reaction also takes place there.
