Answer:

The rocks, the salt water, and the California mussles

Explanation:

The temperature needs to be raised by about 28.15°C to make the catalyzed reaction 100 times faster.

To calculate the temperature increase required to make the catalyzed reaction 100 times faster, we can apply the Arrhenius equation.

The rate constants at temperatures T1 and T2 are denoted by k1 and k2 respectively, while Ea is the activation energy (98.4 kJ mol-1) and R is the gas constant (8.314 J K-1 mol-1).

Since we want the reaction rate to increase by a factor of 100, we can write the ratio of rate constants as k2/k1 = 100. Rearranging the equation and solving for T2, we get:

\(T_2 = (Ea / R)*{ln(k_2/k_1)}^-^1 + T_1\)

Assuming the room temperature T1 is 298 K, we can plug in the values:

\(T_2 = (98.4 * 10^3 J mol^-^1 / 8.314 J K^-^1 mol^-^1) * {ln(100)}^-^1 + 298 K\\T_2 = 326.3 K\)

To convert T2 to degrees Celsius, we subtract 273.15:

T2 = 326.3 - 273.15 ≈ 53.15°C

Therefore, the temperature needs to be raised by about 28.15°C to make the catalyzed reaction 100 times faster.

You can fill in the table for other elements and their respective isotopes by determining the appropriate number of protons, neutrons, and electrons based on the given isotope mass number and atomic number.

To accurately fill in the table with the correct number of subatomic particles for the elements given the isotope mass number, we need to consider the composition of atoms and their respective subatomic particles. Atoms are composed of protons, neutrons, and electrons.

The number of protons in an atom is equivalent to its atomic number, which uniquely identifies the element. The number of neutrons can be determined by subtracting the atomic number from the isotope mass number. Electrons in a neutral atom are equal to the number of protons.

Let's take an example using the isotope mass number:

Isotope: Carbon-14 (mass number = 14)

Element: Carbon (atomic number = 6)Based on the atomic number and isotope mass number, we can determine the number of subatomic particles as follows:

Protons: 6 (same as the atomic number)

Neutrons: 14 - 6 = 8

Electrons: 6 (same as the number of protons in a neutral atom)

The Earth's atmospheric CO2 concentration was around 280ppm before human activities, but since the Industrial Revolution, burning fossil fuels has increased it to above 400ppm, well outside the range.

The concentration of CO2 in the Earth's atmosphere prior to significant human influences was 280ppm.

Before human activities, such as burning fossil fuels, deforestation, and industrial processes, the concentration of carbon dioxide in the atmosphere was relatively stable for thousands of years. This pre-industrial concentration of CO2 was around 280 parts per million (ppm).

To put it into perspective, 280ppm means that for every million molecules of air, around 280 of them were CO2 molecules. This level was maintained through a balance between natural sources of CO2, like volcanic activity and respiration, and natural sinks, such as photosynthesis and ocean absorption.

Since the Industrial Revolution, the burning of fossil fuels has significantly increased the concentration of CO2 in the atmosphere. Currently, the concentration is above 400ppm, which is considered to be well outside the range seen in the past 800,000 years.

In summary, the concentration of CO2 in the Earth's atmosphere prior to significant human influences was approximately 280ppm.

The best explanation for malleability among the given options is (C) The ability of the cations to slide past one another due to the delocalization of the electrons. Option C

Malleability refers to the property of a substance to be deformed or shaped into different forms without breaking or cracking. In metallic substances, such as metals, the atoms are arranged in a closely packed lattice structure held together by metallic bonds.

These metallic bonds involve the delocalization of electrons, meaning that the valence electrons are not bound to specific atoms but instead move freely throughout the metal lattice.

The delocalization of electrons allows for the cations (positively charged ions) to slide past one another when a force is applied. As a result, the metal can be easily deformed into various shapes without disrupting the overall structure.

Option (A) is incorrect because atoms do have internal structures. Option (B) is not specific to malleability and refers more to the concept of potential energy. Option (D) does not accurately explain the mechanism behind malleability. Therefore, option (C) provides the most accurate explanation for why malleability occurs in metallic substances.

Replacing the air inside a metal organ pipe with helium gas would raise the pipe's pitch because helium gas has a lower molecular weight than air. This means that the speed of sound is faster in helium gas than in air. When a pipe is blown, the air molecules inside it vibrate and create sound waves.

The frequency of these sound waves determines the pitch of the note that is produced.

When helium gas is used instead of air, the sound waves travel faster through the lighter gas, resulting in a higher frequency and therefore a higher pitch. This is because the wavelength of the sound waves is shorter in helium gas than in air, so more waves can fit inside the pipe during a given period of time, resulting in a higher frequency.

Overall, replacing the air inside a metal organ pipe with helium gas is a way to alter the pitch of the note produced, making it higher due to the faster speed of sound in helium gas.

Absolute zero is an idea in thermodynamics that describes the lowest energy system.

Thermodynamics

Thermodynamics is the study of thermal energy and heat. One of the most important ideas in thermodynamics is entropy. Entropy is defined as the chaos within a system. Chaos is the movement or different orientations of molecules in a system. Entropy is related to temperature; the higher the temperature, the higher the entropy. High entropy means there is a large amount of chaos in a system, while low entropy is low chaos.

Absolute zero

Absolute zero occurs when the temperature of a system is 0 kelvin or -273.15 °C. Zero kelvin is the theoretical temperature in which entropy equals 0. This means that there is no movement or energy within a system. Absolute zero is the lowest energy a system can possibly have.

The value of ΔG at 1000 K is approximately 123643.2 kJ·mol\(^(-1)\).

To calculate the value of ΔG at 1000 K, we can use the equation:

ΔG2 = ΔG1 + ΔH(T2 - T1)

Where:

ΔG2 is the change in Gibbs free energy at the desired temperature (1000 K)

ΔG1 is the change in Gibbs free energy at the initial temperature (298 K)

ΔH is the change in enthalpy (heat) of the reaction

T2 and T1 are the desired and initial temperatures, respectively.

Given:

ΔH0 = 176 kJ·mol\(^(-1)\)

ΔG0 = 91.2 kJ·mol\(^(-1)\)

T1 = 298 K

T2 = 1000 K

Substituting the values into the equation:

ΔG2 = ΔG1 + ΔH(T2 - T1)

ΔG2 = 91.2 kJ·mol\(^(-1)\) + 176 kJ·mol\(^(-1)\)(1000 K - 298 K)

Now, let's calculate ΔG2:

ΔG2 = 91.2 kJ·mol\(^(-1)\)+ 176 kJ·mol\(^(-1)\)(702 K)

ΔG2 = 91.2 kJ·mol\(^(-1)\) + 123552 kJ·mol\(^(-1)\)

ΔG2 = 123643.2 kJ·mol\(^(-1)\)

b. The available is a vial of Streptomycin powder, which can be reconstituted with 9 mL of sterile water to obtain a concentration of 400 mg/2 mL.

c. The patient will be administered a volume of 1.25 mL of the reconstituted Streptomycin solution.

To calculate the volume to be administered, we first convert the ordered dosage from grams to milligrams: 0.25g = 250mg.

Next, we use the concentration of the reconstituted solution, which is 400 mg/2 mL. This means that 2 mL of the solution contains 400 mg of Streptomycin. We set up a proportion to find the volume (X mL) that contains the required 250 mg:

400 mg / 2 mL = 250 mg / X mL

Cross-multiplying and solving for X, we get:

400 mg * X mL = 2 mL * 250 mg

X = (2 * 250) / 400 = 500 / 400 = 1.25 mL
