Given that an average person burns about 100 calories when running a mile, after eating a candy bar, you must run 2.55 miles to burn it off.

The amount of energy in an item of food or drink is measured in calories.

If a candy bar has 30 g of sugar (which has 4 calories/g) and 15 g of fat (which has 9 calories/g), then the total calories each candy bar has is:

sugar : 30g(4 calories/g) = 120 calories

fat : 15g(9 calories/g) = 135 calories

candy bar = 120 + 135 = 255 calories

If you eat a candy bar that has 255 calories, and an average person can burn 100calories/mile running, then,

x = 255 calories/(100calories/mile)

x = 2.55 miles

where x = number of miles you need to run to burn off the calories

The percent abundance of post-1982 pennies in the sample is 60% as per the given data.

Data sampling is a statistical analysis technique that uses a representative subset of data points to identify patterns and trends in the larger data set under consideration.

To find the percent abundance of post-1982 pennies in the sample data, we need to determine the total number of pennies and the number of post-1982 pennies.

The total number of pennies is:

8 + 12 = 20

To find the number of post-1982 pennies, we need to know the total mass of the pennies. We can use the average mass of the pre-1982 and post-1982 pennies to estimate the number of post-1982 pennies.

The total mass of the pre-1982 pennies is:

8 x 3.1 g = 24.8 g

The total mass of the post-1982 pennies is:

12 x 2.5 g = 30 g

The total mass of all the pennies is:

24.8 g + 30 g = 54.8 g

We can estimate the number of post-1982 pennies by dividing the total mass of the post-1982 pennies by the average mass of a post-1982 penny:

30 g / 2.5 g = 12

So there are 12 post-1982 pennies in the sample.

To find the percent abundance of post-1982 pennies, we can use the following formula:

Percent abundance = (number of post-1982 pennies / total number of pennies) x 100%

Percent abundance = (12 / 20) x 100% = 60%

Therefore, the percent abundance of post-1982 pennies in the sample is 60%.

Answer:

Chlorine is more likely to steal a valence electron from sodium.

Explanation:

Sodium is number 11 on the periodic table with one valence electron. Belonging to the first group, it's one of the alkali metal, which are known to be highly reactive. Chlorine is number 17 with seven valence electrons, and it's in the second-to-last group of halogens--also very reactive.

Considering that elements with one valence electron are just about 100% likely to give up electrons to reach a stable state, sodium would be the element that is more likely to lose its valence electron to chlorine. In other words, chlorine would be the electron thief.

The ratio between the maximum and minimum sound intensities that produce a particular loudness is known as the dynamic range.

The specific ratio can vary depending on the loudness level and the individual's perception.For example, the dynamic range for a loudness level of 60 dB may be around 1,000 to 1, meaning the maximum sound intensity is 1,000 times louder than the minimum sound intensity required to produce that loudness level.

However, in general, the dynamic range for human hearing is estimated to be around 120 decibels, meaning that the loudest sound we can tolerate is around 120 dB greater than the quietest sound we can hear.

Answer:

We can use the ideal gas law to solve for the number of moles of gas:

PV = nRT

where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature in Kelvin.

Plugging in the given values:

(1.35 atm)(25 L) = n(0.0821 L·atm/mol·K)(300 K)

n = (1.35 atm)(25 L) / (0.0821 L·atm/mol·K)(300 K)

n = 1.29 mol

Therefore, there are 1.29 moles of gas in the container.

The reason why the freezing point depression of a solvent depends on the concentration, it is because the solute occupies space between the solvent molecules.

The freezing point depression of a solvent does depend on the concentration of the solute because the solute occupies space between the solvent molecules, thus reducing the number of molecules that can interact.

When a solute is dissolved in a solvent, it takes up space between the solvent molecules. This reduces the number of molecules that can interact, and thus lowers the freezing point of the solvent. The more concentrated the solution, the greater the effect on the freezing point.

The entropy of a substance is related to the number of ways its molecules can arrange themselves in a given volume and energy state. In the case of HCl, the molecule has more degrees of freedom than Ar because it can rotate and vibrate in addition to translating in space. This means that there are more ways that HCl molecules can be arranged in a given volume and energy state compared to Ar, which only has translational motion. As a result, HCl has a higher entropy than Ar.

HCl has a higher entropy than Ar because HCl is a diatomic molecule while Ar is a monatomic gas. In a diatomic molecule like HCl, there are more degrees of freedom, including translational, rotational, and vibrational motions, leading to more possible microstates and thus higher entropy. In contrast, Ar, being a monatomic gas, has fewer degrees of freedom (only translational), resulting in lower entropy.

a) The sphere emits thermal radiation at a rate of 139.75 Watts.

b) The sphere absorbs thermal radiation at a rate of 37.66 Watts.

c) The sphere's net rate of energy exchange is 102.09 Watts.

To calculate the rates of thermal radiation emission and absorption, we can use the Stefan-Boltzmann law, which states that the rate of thermal radiation emitted or absorbed by an object is proportional to its surface area, temperature, and the Stefan-Boltzmann constant.

a) The rate of thermal radiation emitted by the sphere can be calculated using the formula:

Emitting Rate = emissivity * surface area * Stefan-Boltzmann constant * (\(temperature^4 - environment\ temperature^4\))

Plugging in the given values:

Emitting Rate = \(0.924 * (4\pi * (0.457)^2) * 5.67 \times 10^{-8} * ((32.2 + 273.15)^4 - (82.9 + 273.15)^4)\)

Emitting Rate ≈ 139.75 Watts

b) The rate of thermal radiation absorbed by the sphere can be calculated in a similar way but using the environment temperature as the object's temperature:

Absorbing Rate = emissivity * surface area * Stefan-Boltzmann constant * (\(environment\ temperature^4 - temperature^4\))

Plugging in the given values:

Absorbing Rate = \(0.924 * (4\pi * (0.457)^2) * 5.67 \times 10^{-8} * ((82.9 + 273.15)^4 - (32.2 + 273.15)^4)\)

Absorbing Rate ≈ 37.66 Watts

c) The net rate of energy exchange is the difference between the emitting rate and the absorbing rate:

Net Rate = Emitting Rate - Absorbing Rate

Net Rate = 139.75 Watts - 37.66 Watts

Net Rate ≈ 102.09 Watts

Therefore, the sphere emits thermal radiation at a rate of 139.75 Watts, absorbs thermal radiation at a rate of 37.66 Watts, and has a net rate of energy exchange of 102.09 Watts.

Note: The units for all the rates are Watts.
