A. C4H10 + O2 + 4CO2 + H2O + heat
B. C4H10 + O2 + CO2 + H2O + heat
C. C4H10 + O2 + 4C02 + 5H20 + heat
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.

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.

the pH value of 0.1 mol dm-3 of acid U is 1. Which statement is true about acid U?

A) slightly soluble in water
B) reacts only with a weak alkali
C) the degree of ionization in water is high
D) has a low concentration of hydrogen ions​

Answers

Answer:

the degree of ionization in water is high

Explanation:

The term pH is defined as the negative logarithm of hydrogen ion concentration.

Hence;

pH = -log[H^+]

The pH scale shows the degree of acidity or alkalinity of a solution. A solution of pH 1 is a strong acid. A strong acid dissociates completely in solution.

Hence, acid U has a high degree of ionization in water.

Substances that contain a transition metal can be oxidizing. The greater the number of oxidation of this metal, the greater the oxidizing character of the substance. In an industrial process in which the use of an oxidizing agent is necessary, only five substances are available: CaO, FeO, Cu₂O, Cr₂O₃ and KMnO₄.


The substance that should be used in this process, as it has a greater oxidizing character, is:


a) Cr₂O₃


b) Cu₂O


c) CaO


d) FeO


e) KMnO₄

O The inner shell is complete with three electrons. The outer shell is incomplete with three electrons.
O The inner shell is complete with two electrons. The outer shell is incomplete with four electrons.

Answers

Answer:

The inner shell is complete with two electrons. The outer shell is incomplete with four electrons.

Explanation:

There can only be 2 electrons on the first (inner) shell, so it would be complete with two and there needs to be 8 electrons on the outer shell for it to be complete, so it would be incomplete with 4.

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.
