for the oxidation of iron to form iron(iii)oxide
4Fe(s)+3O2(g)=2Fe2O3(s) deltaS^o=-549.73J×K^-1 at 298K
the enthalpy of formation of Fe2O3(s) is -824.2 kj×mol^-1. what is the standard change in gibbs free energy for this reaction at 298K? Delta G^o=delta H^o-T delta S^o
Answer:
only god knows the answer
The Gibbs free energy is given by the change in enthalpy, temperature, and change in entropy. The standard change in Gibbs free energy for oxidation of iron is –1484.6 kJ.
What is Gibbs free energy?Gibbs free energy is the energy present in a thermodynamic system that is used by the reactant to form a product. It is given as,
Δ G° = Δ H° -T ΔS°
The oxidation reaction of iron is given as,
4Fe(s) + 3O₂(g) → 2Fe₂O₃(s)
Given,
ΔS° = –549.73 J∙K⁻¹
T = 298 K
Δ H° = –824.2 kJ∙mol⁻¹
Substituting values above the Gibbs free energy is calculated as:
Δ G° = Δ H° -T ΔS°
= –824.2 kJ∙mol⁻¹ - 298 K ( –549.73 J∙K⁻¹)
= -1484580.46 J
The units of joules are converted into kilojoules and the standard change in Gibbs free energy will be –1484.6 kJ.
Therefore, –1484.6 kJ is the Gibbs free energy.

18 = total
To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. Therefore, there are total 18 electrons in the given compound.
What is atom?Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.
In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron.

Which of the following best explains the age of oceanic crust and ocean-floor features?
A. Seafloor spreading
B. Continental drift
C. Subduction
D.crystallization
The answer option which best explains the age of oceanic crust and ocean-floor features is: A. Seafloor spreading.
Earth crust refers to the outermost layer (thin shell) which makes up the Earth such as igneous, metamorphic, and sedimentary rocks.
Generally, the two (2) main types of Earth crust include:
Continental crust.Oceanic crust.An oceanic crust has a thickness ranging from 5 kilometers to 10 kilometers and it comprises denser rocks such as gabbro, diabase, and basalt.
Seafloor spreading can be defined as a process which involves the formation of new oceanic crust due to volcanic activity and an upwelling of magma at mid-ocean ridges, as well as a subsequent outward movement from the ridge.
Basically, the theory of seafloor spreading can be used to explain in details how a new oceanic crust is created or formed at mid-ocean ridges.
Hence, seafloor spreading best explains the age of oceanic crust and ocean-floor features.

Relate the strength of a weak acid to the strength of a conjugate base.
It’s a textbook question :/
Answer:
There is a relationship between the strength of an acid (or base) and the strength of its conjugate base (or conjugate acid): The stronger the acid, the weaker its conjugate base. The weaker the acid, the stronger its conjugate base. The stronger the base, the weaker its conjugate acid.
explanation
The strength of an acid and a base is determined by how completely they dissociate in water. Strong acids (like stomach acid) break down or dissociate in water. Weak acids maintains their protons in water.

Which of the following is the most common source of pollution?
oil
coal
nuclear
gas
Answer:
Coal puts out more Co2 emissions than Oil or Gas and Nuclear energy plants don't put out any pollution.
Explanation:
Even though Coal is your answer it is actually a very clean form of generating energy. Not only is it very clean but it is the most effecient means. Solar and Wind power can't even come close to the production and turnover that Coal, Gas, and Oil can. Wind Turbines are so innefficent that they somtimes don't even pay off what it took to build them in thier lifetime of service. The production of Wind Turbines puts out more pollution than any of the Coal or Natural Gas Plants. Solar power is not very efficent either but it is on it's way. It is also very expensive.
How much of a 10 M solution is needed to make 1 liter of a 1 M solution
Answer:
0.1 L
Explanation:
M₁ × V₁ = M₂ × V₂
10M × V₁ = 1M × 1L
V₁ = 0.1 L
I hope this helps :)
The molar dilution can be used to estimate the molarity or the volume. 0.1 L of 10 M solution is required to make 1 M of solution.
What is the dilution factor?A dilution factor of the molar concentration is used to calculate the molar concentration or the volume needed to make the diluted solution from the stock.
Given,
M₁ = 10 M
V₁ = ?
M₂ = 1 M
V₂ = 1 L
The volume is calculated as:
M₁ V₁ = M₂ V₂
10 V = 1 × 1
V = 1 ÷ 10
= 0.1 L

What is the molarity of a 0.4 liter solution containing 1.6 moles of NaCl?
Answer:
4 M
Explanation:
Molarity refers to the molar concentration of a substance (solution). It can be calculated by using the formula below:
Molarity (M) = number of moles (n) ÷ volume (V)
According to the information provided in this question;
V = 0.4 liter
n = 1.6 moles
Molarity = n/V
Molarity = 1.6/0.4
Molarity = 4 M

What is the pOH of a solution with an OH- ion concentration of
6.0E-4?
Answer:
3.22
Explanation:
The pOH is defined as:
pOH = - log [OH⁻]
From the problem, we have [OH⁻] = 6.0 x 10⁻⁴.
Thus, we introduce the concentration in the equation to calculate the pOH:
pOH = - log [OH⁻] = -log (6.0 x 10⁻⁴) = 3.22

The oxidation of an unsaturated fatty acid leads to the production of fewer ATPs than a saturated fatty acid with the same number of carbons because ____ A) the oxidation of the fatty acid stops when it reaches the double bond B) unsaturated fatty acids cannot be metabolized C) the double bond results in the bypassing of the first oxidation step of the pathway, thereby eliminating one FADH2 product
Answer:
C) the double bond results in the bypassing of the first oxidation step of the pathway, thereby eliminating one FADH2 product
Explanation:
The beta oxidation of fatty acids is the process by which long chain saturated and unsaturated fatty acids are oxidized to the two-carbon product, acetylCoA.
The beta oxudation of fatty acids occurs in four steps after which the chain length is shortened by 2 with cleavage of an acetylCoA molecule.
The first step involves the oxidation of the fatty acid with introduction of a double bond between C-2 and C-3 of the long carbon chain. This reaction produces FADH2 which donates its electrons to electron carriers in the electron transport chain tomproduce 1.5 moles of ATP. This is the case with saturated fatty acids.
However, in unsaturated fatty acids (which are less reduced than saturated fatty acids) where there is already a double bond innthe molecule, the double bond results in the bypassing of the first oxidation step of the pathway, thereby eliminating one FADH2 product.
This causes a reduction In the number of ATP produced by unsaturated fatty acids when compared to saturated fatty acids.
