Write a word equation for
H2O2 + liver

Answer:

7.16 × 10⁻³ M

Explanation:

Let's consider the reduction reaction of copper during the electroplating.

Cu²⁺(aq) + 2 e⁻ ⇒ Cu(s)

We can calculate the moles of Cu²⁺ present in the solution using the following relations.

The moles of Cu²⁺ reduced are:

[tex]2.30 min \times \frac{60s}{1min} \times \frac{3.00C}{s} \times \frac{1mole^{-} }{96486C} \times \frac{1molCu^{2+} }{2mole^{-} } = 2.15 \times 10^{-3} molCu^{2+}[/tex]

[tex]2.15 \times 10^{-3} moles[/tex] of Cu²⁺ are in 0.300 L of solution.

[Cu²⁺] = 2.15 × 10⁻³ mol/0.300 L = 7.16 × 10⁻³ M

Answer:

B. NH₃ (l) dissolves in water to form a solution

Explanation:

A solution is a uniform or homogenous mixture of two or more substances. The components of a solution are the solute and solvent. The solute is the substance that is being dissolved in another substance. The solvent is the substance which dissolves the solute.

Mixing the given solutes in water results innthe following:

A. Helium being an inert gas does not dissolve in water at all. Therefore, no solution is formed.

B. Liquid ammonia is very solution in water. When mixed with water, it dissolves in water to form aqueous ammonia solution. Aqueous ammonia is an alkaline solution of ammonia dissolved in water.

C. Silicon (iv) oxide, SiO₂, is a crystalline solid whichnis completely insoluble in water. Mixing it with water does not result in the formation of a solution.

D. Pentane, C₅H₁₂, is a liquid hydrocarbon substance which is insoluble in water. It does not mix with water to form a solution, rather it forms two separate immiscible layers of liquids.

Answer:

a. NADH and FADH₂ donate electrons to the electron transport chain

b. Molecular oxygen, O₂, is the final electron acceptor

c. The final products of the electron transport chain and oxidative phosphorylation are as follows: NAD+, FAD+, H₂O, and ATP

Explanation:

The citric cycle oxidize acetylCoA molecules to carbon dioxide and in the process produce the reduced coenzyme NADH and FADH₂. These reduced coenzymes then are able to donate their electrons to various complexes in the electron transport chain. The flow of these electrons through the electron transport chain is coupled to proton pumping out of the mitochondrial matrix into the intermembrane space. Ultimately, the energy of the proton motive force is used to drive synthesis of ATP from ADP and inorganic phospahte and the electrons are accepted by molecular oxygen to produce water. This process is known as oxidative phosphorylation.

Therefore, the answers to the given questions a, b and c are as follows:

a. NADH and FADH₂ donate electrons to the electron transport chain

b. Molecular oxygen, O₂, is the final electron acceptor

c. The final products of the electron transport chain and oxidative phosphorylation are as follows: NAD+, FAD+, H₂O, and ATP

7) Atomic size increases down the group

8) B<Al<Ga<In<Tl

9)Se<C<Ga

10) ionization energy is the energy required to remove electrons from the outermost shell of an atom.

Explanation:

In the periodic table, the properties of elements reoccur ''periodically'' throughout the table, hence the name 'periodic table'.

Ionization energy increases across the period hence the noble gas He has the highest ionization energy.

Since ionization energy increases across the period, group 1 elements possess the lowest ionization energy.

Since atomic size increases down the group and decreases across the period, gallium is smaller than indium, potassium is smaller than caesium, polonium is smaller than titanium and iodine is larger than bromine.

This explanation above justifies the order of increasing atomic radius of group 13 elements shown in answer number 8 above.

Since atomic size decreases across the period, the order of increasing atomic size shown in answer number 9 above is correct.

Ionization energy is the energy required to remove electrons from the outermost shell of an atom.

Answer:

So, look up for electronegativity table

There's a continuum for deciding whether the bond is non-polar, polar, or ionic

If electronegativity difference is less than 0.4 it's non-polar

Answer:

KOH is the limiting reactant

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to identify the required limiting reactant by calculating the moles of water vapor produced by each reactant, CO2 and KOH, as shown below:

[tex]1.4gCO_2*\frac{1molCO_2}{44.01gCO_2}*\frac{1molH_2O}{1molCO_2}=0.0318mol H_2O\\\\2.2gKOH*\frac{1molKOH}{56.11gKOH}*\frac{1molH_2O}{2molKOH}=0.0196mol H_2O[/tex]

In such a way, since 2.2 grams of KOH yield the fewest moles of water vapor, we infer KOH is the limiting reactant.

Answer:

The given molecules are:

CH2Br2

CH3NH2

LiF

C3H8

CF4.

Which compound consists of the hydrogen bond as the strongest intermolecular force.

Explanation:

The hydrogen bond is the electrostatic force of attraction that exists between the covalently bonded H-atom of one molecule and a high electronegative atom (N, O, F) of another molecule.

For example, H-bonding in water is represented below:

Among the given molecules,

CH2Br2 does not have H-bond because there is no either N or O or F atom in it.

In LiF also there is no H-atom and no hydrogen bond.

C3H8 also does not have H-bond in it.

CF4 also does not have H-atom or hydrogen bond in it.

The answer is CH3NH2(methylamine).

It has an intermolecular hydrogen bond in it as shown in the attachment.

The dashed line represents the H-bond.

Answer:

Answer:

1) Hydrolysis

2)Dehydration

3)Dehydration

4)Hydrolysis

Explanation:

Hydrolysis is the chemical breakdown of substances by water and depends on the chemistry, solubility, pH, and the oxidation–reduction (Eh or redox) potential of compound

https://www.sciencedirect.com/topics/earth-and-planetary-sciences/hydrolysis

With hydrolysis water will be a reactant, not a product, and is associated with breaking down substances. Hence 1 and 4 being a Hydrolysis reaction.

Dehydration on the other hand, is defined as :

In a dehydration reaction, either a hydroxyl group from one molecule combines with a hydrogen atom from the other molecule, or two hydrogen atoms from one molecule combine with an oxygen atom on the other molecule. In either case, water is released, and the two molecules are joined together.

https://www.albert.io/blog/dehydration-synthesis-ap-biology-crash-course/

Therefore it is associated with creating a bond of sorts, and water is a product, which is why 2 and 3 are dehydration.

Hope this helps!

The matching of the description with either a dehydration reaction or a hydrolysis reaction is as follows:

A Dehydration reaction may be defined as a type of chemical reaction that significantly involves the elimination or removal of water from the reactant molecules. In this type of reaction, water is definitely one of the products.

Hydrolysis reaction is just opposite to the dehydration reaction. It is also known as hydration reaction. It is a type of decomposition reaction that involves water as reactant. It is a type of chemical reaction in which a molecule of water stimulates and breaks one or more chemical bonds in the entire reaction.

Therefore, the matching of the description with either a dehydration reaction or a hydrolysis reaction is well described above.

Fission, the splitting of uranium atoms, is the source of nuclear energy. This produces heat that creates steam, which a turbine generator uses to produce power. Nuclear power stations do not emit greenhouse gases since they do not burn fuel.

The energy found in an atom's nucleus, or core, is referred to as nuclear energy. All everything in the cosmos is made up of microscopic building blocks called atoms, and the nucleus is held together by energy. The compact nucleus of an atom has a tremendous amount of energy.

Atoms may generate enormous amounts of energy through two physical processes called fission and fusion. Through nuclear reactions, they produce millions of times more energy than conventional sources.

Nuclear fusion occurs in the sun and produces solar energy. In the sun's core, fusion happens when the protons of colliding hydrogen atoms fuse to form helium atoms.

Thus, Fission, the splitting of uranium atoms, is the source of nuclear energy.

Answer:

1.58×10¯⁷ M.

Explanation:

From the question given above, the following data were obtained:

pH = 6.8

Concentration of hydronium ion [H₃O⁺] =?

The pH of a solution is given by the following equation:

pH = –Log [H₃O⁺]

With the above formula, we can obtain the concentration of hydronium ion [H₃O⁺] as follow:

pH = 6.8

Concentration of hydronium ion [H₃O⁺] =?

pH = –Log [H₃O⁺]

6.8 = –Log [H₃O⁺]

Multiply both side by by –1

–6.8 = Log [H₃O⁺]

Take the anti log of –6.8

[H₃O⁺] = antilog (–6.8)

[H₃O⁺] = 1.58×10¯⁷ M

Therefore, the concentration of hydronium ion [H₃O⁺] in the solution is 1.58×10¯⁷ M.

Explanation:

Alkenes undergo hydrogenation to give the corresponding alkanes. Where the structure of the original alkene is unknown, we can deduce the structure of the alkene from the structure of the products obtained when it undergoes various chemical reactions.

Now, the fact that we obtained 2-methylhexane upon hydrogenation and the two compounds had different heats of hydrogenation means that the two compounds were geometric isomers. The original compounds must have been cis-2-methyl-3-hexene and trans-2-methyl-3-hexene.

When reacted with HCl, the same compound C7H15Cl is formed because the stereo chemistry is removed.

However, we know that the trans isomer is more stable than the cis isomer hence the cis isomer always has a higher heat of hydrogenation than the trans isomer. Thus X is cis-2-methyl-3-hexene.
