A Questic
Is the following reaction feasible at 340K? Mg + ZnO -> MgO + Zn Enthalpy Data: Mg: 0 kJ/mol ZnO: -348 kJ/mol MgO:-602
kJ/mol Zn: 0 kJ/mol Entropy Data: Mg: 33 J/K mol ZnO: 44 J/K mol MgO: 42 J/K mol Zn: 27 J/K mol
A. No, it is not feasible because the Gibbs free energy change is negative.
OB. Yes, it is feasible because the Gibbs free energy change is negative.
C. No, it is not feasible because the Gibbs free energy change is positive.
D. Yes, it is feasible because the Gibbs free energy change is positive.

Answers

Answer:

No, it is not feasible because the Gibbs free energy change is positive

Explanation:

∆Hreaction= (-602 KJ/mol) - (-348 KJ/mol) = -254 KJ/mol

∆Sreaction = (42 + 27) J/Kmol - (33 + 44) J/K = -8J/Kmol

From;

∆G = ∆H - T∆S

∆G = 254 × 10^3 J/mol - [340K × (-8 J/Kmol)]

∆G = 2.57 × 10^5 J/mol

Note that when the change in free energy is positive, a reaction is non spontaneous. Only a reaction that has a negative change in free energy is spontaneous.

Answer:

B. Yes, it is feasible because the Gibbs free energy change is negative.

Karma is saying to add water to acid.By which acid will be diluted and become less hazardous.Sonam is saying to add an indicator .She is advising wrong .Indicator won't absorb much acid.For which this is uneffective unless it changes a colour.Sangay's idea is also fluff.Salt won't react with acid to neutralise. Because both contains halogens.Like Sodium chloride is a salt and Hydrochloric acid is also a salt.Yes,Tshering's idea is quite good.by this acid will be neutralized some.Thsomo's idea is also good .Its better to call teacher but we should solve it by ourselves.I think karma's suggestion is best .It is better to dilute the acid .But we should add water while mixing acid with spoon .

Enolase, an enzyme that catalyzes the conversion of 2-phosphoglycerate to phosphoenolpyruvate: Group of answer choices demonstrates a base-catalysis step, where a proton is removed from the substrate. demonstrates an acid-catalysis step, where a proton is added to the substrate. requires two Mg2 cofactors and as such demonstrates metal-ion catalysis. stabilizes the intermediate and transition

Answers

Answer:

Requires two Mg²⁺ cofactors and as such demonstrates metal-ion catalysis

Explanation:

Electrostatic catalysis or metal ion catalysis is a catalytic mechanism that makes use of metalloenzymes, such as enolase along with a metal ion which is bound tightly, including, Mo⁶⁺, Ni³⁺, Co³⁺, Mn²⁺, Zn²⁺, Cu²⁺, and Fe²⁺, to undertake a catalysis

For maximal activity, enolase requires the presence of 2 equivalent metal ions in each site which is active

Therefore, the correct option is; requires two Mg²⁺ cofactors and as such demonstrates metal-ion catalysis

What happens when The vapour obtained by dropping conc. H2SO4 in a mixture of KI and MnO2 is treated with hypo solution​

Answers

The reaction between H2SO4 in a mixture of KI and MnO2 yields iodine which reacts with hypo solution​ by titration and the iodine is decolorized.

Iodine is decolorized.

The first reaction stated in the question occurs as follows;

2 KI (aq) + 2 H2SO4 (aq) + MnO2 (s) → MnSO4 (aq) + K2SO4 (aq) + I2 (s) + 2 H2O (l)

The reaction here is the formation of iodine from MnO2 and KI in the presence of dropwise H2SO4.

Hypo is the common name of sodium thio-sulphate or sodium hypo-sulfite.

The equation of the titration reaction is;

2Na2S2O3 + I2→ Na2S4O6 + 2NaI

When this reaction takes place, iodine is decolorized due to its reduction to I^-.

I'm having trouble understanding what "the difference in energy between the products and reactants from the surroundings" means. Can you help explain what this means? please​

Answers

Answer:

The energy change in a chemical reaction is due to the difference in the amounts of stored chemical energy between the products and the reactants. This stored chemical energy, or heat content, of the system is known as its enthalpy.

Explanation:

Due to the absorption of energy when chemical bonds are broken, and the release of energy when chemical bonds are formed, chemical reactions almost always involve a change in energy between products and reactants. By the Law of Conservation of Energy, however, we know that the total energy of a system must remain unchanged, and that oftentimes a chemical reaction will absorb or release energy in the form of heat, light, or both.

D. C4H10 +6.502 → 4002 + 5H20 + heat
SUBMIT

Answers

Answer:

D. C₄H₁₀ + 6.5O₂ → 4CO₂ + 5H₂O + heat

Explanation:

The reaction of the combustion of isobutane with oxygen is presented as follows;

C₄H₁₀ + 6.5O₂ → 4CO₂ + 5H₂O + heat

In the above reaction, the number of elements on the reactant side are;

4 carbon, C, atoms, 10 hydrogen, H, atoms, and 13 oxygen, O, atoms

The number of elements on the product side of the above chemical reaction are;

The number of carbon atoms, C = 4

The number of hydrogen atoms, H = 10

The number of oxygen atoms, O = 13

Therefore, the number of atoms on the reactant side of the chemical equation are equal to the number of atoms on the product side, and the combustion reaction for isobutane is balanced.

Answer:

A and D are the answers

Explanation:

the other two don't make sense

The statements C and D are correct, i.e., curly hair have different protein structure from straight hair and curly hair results from a change in the gene.

What is protein?

Proteins are biomolecules made of amino acids. Proteins are very essential to all living things and contributes the body structure. Proteins are mainly up taken through diet and they are the main source of energy.

Hair is made of keratin protein. Keratin makes up our skin and nails too.Curly hair is originating by birth not developing over time. Curly hair is more likely to be occurring through inheritance.

The protein structure the hair follicle is some more bend for curly hair. Curly hair and straight hair originates from different gene traits. The gene type is inherited from the parents.

Hence, for people with curly hair have different protein structure and it result from a change in gene that code for hair structure. Thus options C and D are correct.
