The balanced half-reaction in which sulfate ion is reduced to sulfite ion is a ________ process. Group of answer choices a) four
Aleks [24]

Answer:

The balanced half-reaction in which sulfate ion is reduced to sulfite ion is a two electron process

Explanation:

In the sulfate anion, S, acts with +6 in the oxidation number

SO₄⁻²

This is the anion from the sulfuric acid, when it lost the 2 protons

H₂SO₄  →  2H⁺  +  SO₄⁻²

In the sulfite anion, S, acts with +4 in the oxidation number.

SO₃⁻²

This is the anion, generated when the sulfurose acid lost the 2 protons.

H₂SO₃  → SO₃⁻²  +  2H⁺

In acidic medium

2H⁺  +  SO₄⁻²   + 2e⁻  →   SO₃⁻²  +  H₂O

In basic medium

H₂O  + SO₄⁻²   + 2e⁻  →   SO₃⁻²  + 2OH⁻

Question 2 (1 point)
alisha [4.7K]

To calculate an electron configuration, divide the periodic table into sections to represent the atomic orbitals, the regions where electrons are contained. Groups one and two are the s-block, three through 12 represent the d-block, 13 to 18 are the p-block and the two rows at the bottom are the f-block.

The reaction between iodine and carbon dioxide to yield diiodine pentoxide is exothermic. How could the yield of diiodine pentox
Romashka [77]

Answer:

Increasing the temperature

Explanation:

According to Le Chatelier's principle, "if any of the conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".

Since the forward reaction is exothermic, this suggests that heat is given off in the reaction.

Increasing the temperature will favors the reverse process which is endothermic.

In going from the reactants to the the products, the reaction is deemed exothermic which suggests that it produces heat.

The backward reaction is endothermic i.e it absorbs heat. If the temperature is increased, this process will be favored and more reactants produced. Less of the diiodine pentoxide will form. There is a leftward shift of the equilibrium

A(n) ____________ releases H+ in water, therefore it must have one or more ___________ atoms as part of its structure.
shtirl [24]

An acid releases H^{+}  in water , therefore it must have one or more <u>hydrogen  </u>atoms as part of its structure .

Acids are chemical compounds that release hydrogen ions (H+) when placed in water. For example, when hydrogen chloride is placed in water, it releases its hydrogen ions and the solution becomes hydrochloric acid. Bases are chemical compounds that attract hydrogen atoms when they are placed in water.

A hydrogen ion is created when a hydrogen atom loses or gains an electron. A positively charged hydrogen ion (or proton) can readily combine with other particles and therefore is only seen isolated when it is in a gaseous state or a nearly particle-free space.
