Answers

Answer 1

Among the given reactions, those reaction which is an oxidation half-reaction is Fe → Fe³⁺ + 3e⁻.

What is oxidation reaction?

Oxidation reaction in terms of electron will be described as those reactions in which removal of electron takes place.

V³⁺ + e⁻ → V²⁺

In this reaction addition of electron takes place, so it is not an oxidation reaction.

Fe → Fe³⁺ + 3e⁻

In this reaction removal of electrons takes place, so this is an oxidation reaction.

C⁴⁺ + 2e⁻ → C²⁺

In this reaction addition of electron takes place, so it is not an oxidation reaction.

Hence Fe → Fe³⁺ + 3e⁻ shows oxidation half-reaction.

how do i solve this?

Answers

Answer:

57.6g

Explanation:

In the balanced equation H2O and Mg(OH)2 have the same coefficient (1) so we know that 3.2 moles of H2O react to form 3.2 moles of Mg(OH)2. Now we just have to calculate the mass of the H2O which we can do by finding the molar mass from the periodic table. For this just add the molar masses of the consituent atoms. (2(1)+1(16))=18g/mol H2O. Now that we know the molar mass we just have to multiply it by the amount of moles. 18*3.2=57.6g H2O

For the reaction H2O(g) + Cl2O(g) → 2HCIO(9), you know S rxn and Sosys and S° of HCIO(g) and of H2O(g). Write an expression that can be used to determine Cl2O(g)

Answers

The expression that can be used to determine Cl2O(g) is ;

[tex]S_{cl_{2}o(g) } ^{o} = 2S_{HCIO(g)} ^{o} - S_{H_{2}O(g) }^{o} - \beta S_{rxn} ^{o}[/tex]

Determine an expression that can be used to determine Cl2O(g)

The general expression for ΔS°rxn of a chemical reaction

ΔS°rxn = ∑mS°products - ∑nS°reactants

where ; m and n = stoichiometry coefficients

Considering the given reaction : H₂O(g) + Cl₂O(g) → 2HCIO (g)  

[tex]\beta[/tex]S°rxn  = [tex]2S_{HCIO(g)} ^{o} - S_{H_{2}O(g) } ^{o} - S_{Cl_{2}O } ^{o}[/tex] ------- ( 2 )

Rearranging the equation above

[tex]S_{cl_{2}o(g) } ^{o} = 2S_{HCIO(g)} ^{o} - S_{H_{2}O(g) }^{o} - \beta S_{rxn} ^{o}[/tex]

Hence we can conclude that The expression that can be used to determine Cl2O(g) is ;

[tex]S_{cl_{2}o(g) } ^{o} = 2S_{HCIO(g)} ^{o} - S_{H_{2}O(g) }^{o} - \beta S_{rxn} ^{o}[/tex]

The reaction below consistently yields 82% of the theoretical value. If you need to make 10 g of Mg(OH)2 How much Mg3N2 (g) should you use (assume that you will use H2O in excess).

Mg3N2(s) + H2O(l) → Mg(OH)2(s) + NH3(g)
Help me please!

Answers

If excess [tex]H_2O[/tex] is used as stated in the illustration the amount of [tex]Mg_3N_2[/tex] that would be required would be 7.57 grams

Stoichiometric calculation

From the equation of the reaction:

[tex]Mg_3N_2(s) + 6H_2O(l) --- > 3Mg(OH)_2(s) + 2NH_3(g)[/tex]

Since the yield is 80% of the theoretical value, in order to make 10g, the theoretical yield would be 12.5 g.

Mole ratio of [tex]Mg_3N_2[/tex] and [tex]Mg(OH)_2[/tex] = 3:1

Mole of 12.5 g  [tex]Mg(OH)_2[/tex] = 12.5/53.32 = 0.225moles

Equivalent mole of [tex]Mg_3N_2[/tex]  = 0.124/3 = 0.075 moles

Mass of 0.0041 moles  [tex]Mg_3N_2[/tex] = 0.075 x 100.95 = 7.57 grams

Scientists used to believe that chemical reactions fueled the sun. Why did this lead them to believe that the sun was very young? What kind of reactions do we now think are responsible for the energy released by the sun? In one to two sentences , explain your reasoning 2 points )

Answers

The energy produced by the sun is as a result of nuclear reactions which produces large amounts of energy.

What are chemical reactions?

Chemical reactions are reactions which occur as a result of a rearrangement of atoms of elements to form new combinations of substances known as compounds.

Since chemical reactions which have relatively short lifespans, scientist would have assumed that the sun is very young.

However, nuclear reactions have been proven to be the means by which the sun produces its energy.

Nuclear reactions release large amounts of energy and have relatively long lifespans.

Therefore, the energy produced by the sun is as a result of nuclear reactions.

Answers

Answer:

im assuming its due to something like water on water not eing as bad as the thwap of water on land. this wasnt a test question was it?

Explanation:

Answer:

As the tsunami waves become compressed near the coast, the wavelength is shortened and the wave energy is directed upward - thus increasing their heights considerably. Just as with ordinary surf, the energy of the tsunami waves must be contained in a smaller volume of water, so the waves grow in height. and they can't do damage out in the middle of the ocean because there is not much to damage out in sea
