Answers
The term that the scientist would use in this case is partial pressure. Option D
What is the partial pressure?
The pressure that one particular gas component within a mixture of gases exerts is referred to as partial pressure. It is the pressure that the gas would experience at the same temperature if it were the only thing in the entire volume.
When researching gas mixtures, such as in gas laws, gas phase equilibria, and gas collecting methods, partial pressures are extremely crucial for the gas.

1. Methanol is a high-octane fuel used in high performance racing engines. 2 CH3OH(l) + 3O2(g) → 2CO2(g) + 4 H20(g) a) Calculate ∆H० and ∆S० using thermodynamic data, and then ∆G
Answers
Answer:
The reaction given in the question is:
2CH₃OH (l) + 3O₂ (g) ⇒ 2CO₂ (g) + 4H₂O (g)
The values of ΔH°formation and ΔS° of the reactants and products given in the reaction based on the thermodynamics data is:
ΔH°formation values of CH3OH (l) is -238.4 kJ/mol, CO2(g) is -393.52 kJ/mol, H2O (g) is -241.83 kJ/mol and O2 (g) is 0.
The S° values of CH3OH (l) is 127.19 J/molK, CO2(g) is 213.79 J/molK, H2O (g) is 188.84 J/moleK, and O2 (g) is 205.15 J/molK.
Now the values of ΔH° and ΔS° are,
ΔH°rxn = 2 * ΔH°formation CO2 (g) + 4 * ΔH°formation H2O (g) - 2*ΔH°formation CH3OH (l)
ΔH°rxn = 2 * (-393.52) + 4 (-241.83) -2 * (-238.4)
ΔH°rxn = -1277.56 kJ/mole
ΔS°rxn = 2 * S° CO2 (g) + 4 * S° H2O (g) - 2*S° CH3OH (l) - 3 * S° O2 (g)
ΔS°rxn = 2 * 213.79 + 4 * 188.84 - 2 * 127.19 - 3*205.15
ΔS°rxn = 313.11 J/mole/K
Now the formula for calculating ΔG°rxn is,
ΔG°rxn = ΔH°rxn - TΔS°rxn
ΔG°rxn = -1277.56 * 1000 J/mole - 298 * 313.11 J/mole
ΔG°rxn = -1370.86 kJ/mol

Explanation:
I'm not the best at biology, but natural selection a term we use that's describes nature's way of choosing the strongest to survive. The species with the strongest adaptations will survive while the others will die off. For example, if a school of fish was forced to live in a colder habitat than usual, over many years some fish will adapt to that environment and be able to withstand it. But, some fish won't get those adaptations and be killed off. But, future generations will be born with that ability to withstand the cold environment and it would become normal. So, natural selection changes the way a species lives. Hope this helps

C. An electron EMITS a photon as it goes from a LOWER TO HIGHER energy level.
D. An electron ABSORBS a photon as it goes from a LOWER TO HIGHER energy level.
Answers
The correct response is B. An electron EMITS a photon as it goes from a HIGHER TO LOWER energy level.
What is electron?A subatomic particle with a negative electric charge is called an electron. Together with protons and neutrons, it is one of the fundamental particles that make up an atom.
When an atom is excited, its electrons have the ability to transition from one energy level to another. These stimulated electrons will eventually revert to their initial lower energy levels since they are unstable. They do this by releasing energy in the form of particular wavelength photons. Each element has a distinct set of energy levels, which leads to the emission of photons at a certain wavelength and the formation of a distinct emission spectrum.
In this instance, the existence of a line in the emission spectrum's blue section shows that an electron has released a photon with a certain wavelength that corresponds to the region's blue color. A photon with an energy equal to the difference between the two levels is released when an excited electron returns from a higher energy level to a lower energy level.

O The energy released in the first move equals the energy absorbed in the second move.
The energy released in the first move is greater than the energy absorbed in the second move.
Answers
Answer:
Your answer would be B because In the first move energy was absorbed, because when energy is gained an electron moves to a higher energy level in the second move energy will be released because that is how an atom moves to a lower energy level. The jump from level 1 to 4 was bigger than the drop from 4 to 2, because in the first move it moved from more orbitals. thus describing the the energy in the first move had a far energy released in the second move.
