Answer:

$HCO^-_3+HBrO\rightleftharpoons H_2CO_3+BrO^-$

Explanation:

Hello there!

In this case, according to the Brønsted-Lowry theory of acids, it is possible to realize that HBrO acts as the Brønsted-Lowry acid as it has a free hydrogen to give away to HCO₃⁻ which acts as the Brønsted-Lowry base able to accept the incoming hydrogen; therefore, the Brønsted-Lowry reaction is:

$HCO^-_3+HBrO\rightleftharpoons H_2CO_3+BrO^-$

Best regards!

The question is incomplete, the complete question is:

Using relative enthalpy and entropy values, determine how the process is affected after each of the following temperature or pressure changes? Consider that a more effective reaction produces more product or more product in a shorter amount of time.

Reaction: SO2 (g) + 2H2S (g) ↔ 3S(s) + 2H2O (g)

Substance | ΔG kJ/mol | ΔH kJ/mol

H2O(g) | -228.6 | -241.8

H2O(l) | -237.1 | -285.8

SO2(g) | -300.4 | -296.9

SO3(g) | -370.4 | -395.2

H2S(g) | -33.01 | -20.17

S(s) | 0 | 0

- Temp. decreases while maintaining container size

- Temp. increases while maintaining container size

- Pressure decreases while maintaining container size

- Pressure increases while maintaining container size

Answer:

Explanation:

ΔH∘rxn=ΔH∘f(products)−ΔH∘f(reactants)

ΔH∘rxn= [0+2(-241.8)] - [(-296.9) + 2(-20.7)]= -145.6KJ/mol

ΔG∘rxn=[(0+ 2(-228.6) -[(-300.4) + 2(-33.01)]= -90.78KJ/mol

The reaction is spontaneous since ΔG∘rxn is negative

The reaction is exothermic since ΔH∘rxn= negative

1) increase in pressure is less effective because it favours the reverse reaction.

2) increase in temperature is less effective since it favours the reverse reaction given that the reaction is exothermic in nature

3) decrease in pressure is more effective, it favours the forward reaction

4)Decrease in temperature is more effective because it favours the forward reaction.

Nitrobenzene contains 5 hydrogen atoms, 6 carbon atoms, 2 oxygen atoms, and 1 nitrogen atom. what is the chemical formula for ni

ollegr [7]

C₆H₅NO₂

<h3>Further explanation</h3>

Nitrobenzene contains:

5 hydrogen atoms,
6 carbon atoms,
2 oxygen atoms, and
1 nitrogen atom.

The chemical formula for nitrobenzene is C₆H₅NO₂.

Nitrobenzene is one of benzene derivatives, precisely including the type of monosubstituted benzenes.

The molecular structure of phenyl $\boxed{ \ C_6H_5- \ }$ is formed by removing one H atom from the benzene $\boxed{ \ C_6H_6 \ }$ molecule. A substituent is bound to the C atom which loses the H atom so it is called monosubstituted benzene.

In the naming of monosubstituted benzenes, benzene is the parent name and the substituent is indicated by a prefix.

nitro is the substituent
benzene is the parent name

When benzene is reacted with a mixture of concentrated nitric acid and concentrated sulfuric acid, it yields nitrobenzene.

$\boxed{ \ C_6H_6 + HNO_2 \ (with \ H_2SO_4 \ in \ 30^0C-40^0C) \rightarrow C_6H_5NO_2 + H_2O}$

<u>Notes:</u>

Benzene and compounds having similar chemical properties to benzene are called aromatic compounds.
Benzene is a colorless, poisonous liquid with a specific odor. it dissolves in organic solvents in organic solvents such as alcohol, ether, and acetic acid. Benzene is also good for non-polar substances.
Nitrobenzene is used in the manufacture of aniline and other organic chemicals. Nitrobenzene is a pale yellow, oily, and highly toxic liquid with the odor of bitter almonds.

A drop of vinegar ( a weak acid ) is placed on a sample of each of the materials below. Which will show the most active reaction

professor190 [17]

Answer: Option (B) is the correct answer.

Explanation:

Marble is also known as calcium carbonate and its chemical formula is $CaCO_{3}$ .

When it combines with vinegar then it results in the formation of calcium acetate which is a water soluble compound along with the release of carbon dioxide which occurs in the form of bubbles and water.

The reaction is as follows.

$CaCO_{3} + CH_{3}COOH \rightarrow Ca(CH_{3}COOH)_{2} + H_{2}O + CO_{2}$
