Answer:

A. The total amount of energy does not change during an energy

conversion.

Explanation:

It states that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another. In other words, the total energy of an isolated system remains constant over time, and energy cannot be created or destroyed, only converted from one form to another.

The correct answer is 1.5 m/s

Explanation:

To find the average speed of the movement of a body, for example, the movement of the marble. The first step is to know the total distance traveled and the time of the movement. These two details can be found in the graph presented, in this, the maximum distance (vertical axis) is 15 meters and at this distance, the time is 10 seconds. Now, with this information we can use the formula Average speed = Total distance ÷ Total time.

\(Average speed = \frac{15 meters}{10 seconds}\)

\(Average speed= 1.5 m/s\)

According to this, the correct answer is 1.5 m/s. Also, meters per second or m/s is the correct unit because the distance is provided in meters (m) and the time is provided in seconds (s).

Explanation:

Solid Snake (75 kg) carries 18 kg of equipment. If Solid Snake climbs 27 flights of stairs, each 5.5 m in height, the work done against gravity is 135.34 kJ (c).

In physics, work is the energy transferred to or from an object via the application of force along a displacement.

In this problem, the force that does the work is the one that opposes the weight.

Solid Snake is 75 kg and is carrying 18 kg of equipment. The total mass is:

m = 75 kg + 18 kg = 93 kg

We can calculate the weight using Newton's second law of motion.

F = m . g = 93 kg . 9.8 m/s² = 911.4 N

Solid Snake climbs 27 flights of stairs, each 5.5 m in height.

27 . 5.5 m = 148.5 m

We will use the definition of work.

w = F . s = (911.4 N) . (148.5 m) . (1 kJ/1000 J) = 135.34 kJ

Solid Snake (75 kg) carries 18 kg of equipment. If Solid Snake climbs 27 flights of stairs, each 5.5 m in height, the work done against gravity is 135.34 kJ (c).

Answer:

0.02moles

Explanation:

To answer this question, the general gas law equation is used. The General gas law is:

Pv = nRT

Where; P = standard atmospheric pressure (1 atm)

V = volume (L)

n = number of moles

R = Gas law constant

T = Temperature

For this question; volume = 1.00L, atmospheric pressure (P) = 1 atm, R = 0.0821 L-atm / mol K, T = 600K, n = ?

Therefore; Pv = nRT

n = PV/RT

n = 1 × 1/ 0.0821 × 600

n = 1/49.26

n = 0.0203moles

Hence, there are 0.02 moles of gas.

The number of mole of the gas present in the cylinder is 0.02 mole

From the question given above, the following data were:

Temperature (T) = 600 K

Volume (V) = 1 L

Pressure (P) = 1 atm

The number of mole of the gas present in the cylinder can be obtained by using the ideal gas equation (PV = nRT) as illustrated below:

Temperature (T) = 600 K

Volume (V) = 1 L

Pressure (P) = 1 atm

Gas constant (R) = 0.0821 atm.L/Kmol

1 × 1 = n × 0.0821 × 600

1 = n × 49.26

Divide both side by 49.26

\(n = \frac{1}{49.26}\\\\\)

Thus, 0.02 mole of the gas is present in the cylinder.

Answer:

I believe the best answer is B. Copper.

The current passing through the electrolytic cell is approximately 2.02 x 10^4 Amperes.

To calculate the current in amperes, we need to use Faraday's laws of electrolysis and the stoichiometry of the reaction.

Faraday's laws state that the amount of substance produced or consumed during electrolysis is directly proportional to the quantity of electricity passed through the cell. The relationship is given by:

Q = nF

Where Q is the electric charge in coulombs (C), n is the number of moles of substance involved in the reaction, and F is Faraday's constant, which is equal to 96,485 C/mol.

In this case, the substance being produced is Cl2, and we know the mass of Cl2 produced, which is 4.8 x 10^5 g.

First, we need to calculate the number of moles of Cl2 produced:

Molar mass of Cl2 = 35.45 g/mol

Moles of Cl2 = mass / molar mass = (4.8 x 10^5 g) / (35.45 g/mol) ≈ 1.354 x 10^4 mol

Now we can calculate the quantity of electricity passed through the cell using Faraday's laws:

Q = nF

Q = (\(1.354 x 10^4\)mol) * (96,485 C/mol)

Q ≈ 1.308 x 10^9 C

The quantity of electricity is given in coulombs. To find the current, we need to divide this value by the time in seconds.

Given that the time is 18 hours, we convert it to seconds:

Time = 18 hours * 60 minutes/hour * 60 seconds/minute

Time = 6.48 x 10^4 seconds

Finally, we can calculate the current:

Current (I) = Q / Time

I = (1.308 x 10^9 C) / (6.48 x 10^4 s)

I ≈ 2.02 x 10^4 Amperes

Therefore, the current passing through the electrolytic cell is approximately 2.02 x 10^4 Amperes.

Use a ratio of 0.44 mol lactate to 1 mol of lactic acid  

Explanation:

John could prepare a lactate buffer.

He can use the Henderson-Hasselbalch equation to find the acid/base ratio for the buffer.

\(\text{pH} = \text{pK}_{\text{a}} + \log\dfrac{\text{[A$^{-}$]}}{\text{[HA]}}\\\\3.5 = 3.86 + \log\dfrac{\text{[A$^{-}$]}}{\text{[HA]}}\\\\\log\dfrac{\text{[A$^{-}$]}}{\text{[HA]}} = 3.5 - 3.86 = -0.36\\\\\dfrac{\text{[A$^{-}$]}}{\text{[HA]}} = 10^{-0.36} = \mathbf{0.44}\)

He should use a ratio of 0.44 mol lactate to 1 mol of lactic acid.

For example, he could mix equal volumes of 0.044 mol·L⁻¹ lactate and 0.1 mol·L⁻¹ lactic acid.

In Atlanta, GA, certain seasons are associated with poorer air quality due to various factors such as weather conditions, human activities, and geographical location.

Typically, the seasons with the worst AQI in Atlanta, GA, are summer and early fall. This is primarily due to the combination of high temperatures, stagnant air masses, and increased pollution from various sources.

During the summer months, Atlanta experiences hot and humid weather, which can contribute to the formation of ground-level ozone. Ozone is a harmful pollutant that is created when pollutants from vehicles, power plants, and industrial activities react with sunlight and heat. High levels of ozone can cause respiratory issues and other health problems.

In addition to ozone, Atlanta also experiences increased levels of particulate matter (PM) during the summer and early fall. PM refers to tiny particles suspended in the air, which can come from sources such as vehicle exhaust, industrial emissions, and wildfires.

These particles can be inhaled into the lungs and can have detrimental effects on respiratory health.

It's important to note that air quality can vary from year to year and is influenced by various factors. Local regulations, weather patterns, and changes in pollutant emissions can all impact the AQI during different seasons.

The expression for Keq for the reaction is 0.25

The expression for Keq represents the relative concentrations of the products and reactants in a chemical reaction at a given temperature and pressure. To calculate Keq, one must first balance the chemical equation for the reaction and then determine the concentrations of all species involved in the reaction at equilibrium.

In this case, the balanced chemical equation for the reaction between 0.1 M AgNO3 and a saturated solution of PbCl2 is

AgNO3(aq) + PbCl2(aq) ⇌ AgCl(s) + Pb(NO3)2(aq)

At 25°C, the initial concentrations of AgNO3 and PbCl2 are 0.1 M and unknown, respectively. The reaction is performed by mixing 50 mL of 0.1 M AgNO3 with 50 mL of a saturated solution of PbCl2, so the final volume of the solution is 100 mL.

Once the reaction has reached equilibrium, the concentration of AgCl can be measured and the concentration of Pb(NO3)2 can be calculated using the stoichiometry of the balanced chemical equation. With these values, the expression for Keq can be calculated using the following formula:

Keq = [AgCl] [Pb(NO3)2] / [AgNO3] [PbCl2]

Where [AgCl], [Pb(NO3)2], [AgNO3], and [PbCl2] represent the concentrations of AgCl, Pb(NO3)2, AgNO3, and PbCl2 at equilibrium, respectively.

Given the concentration values, the expression for Keq can be calculated using the following formula:

Keq = [AgCl] [Pb(NO3)2] / [AgNO3] [PbCl2]

Plugging in the given values:

Keq = 0.05 M * 0.03 M / (0.1 M * 0.06 M)

= 0.25

Therefore, the expression for Keq for the reaction is 0.25.

pH = 14 - 7

pH = 7

4. pH + pOH = 14

pOH = 14 - pH

pOH = 14 - 4.3

pOH ≈ 9.7

Now,

[H⁺] × [OH⁻] = 1.0 x 10⁻¹⁴

[OH⁻] = 1.0 x 10⁻¹⁴ / [H⁺]

[OH⁻] = 1.0 x 10¹⁴ / 10^(-pOH)

[OH⁻] = 1.0 x 10⁻¹⁴ / 10^(-9.7)

[OH⁻] ≈ 1.99 x 10⁻⁶ M
