Answer:

Question is incomplete, the complete question is pasted below.

Consider the following equilibrium. 2SO2(g) + O2(g) ⇌2SO3(g) The equilibrium cannot be established when ________ is/are placed in a 1.0-L container?

A) 0.50 mol O2 (g) and 0.50 mol SO3 (g)

B) 1.0 mol SO3 (g)

C) 0.25 mol SO2 (g) and 0.25 mol O2 (g)

D) 0.75 mol SO2 (g)

E) 0.25 mol of SO2 (g) and 0.25 mol of SO3 (g)

Answer:

The correct answer is : D) 0.75 mol SO2 (g)

Explanation:

Option A is not true because both SO3 can be converted into SO2 and O2 and equilibrium can be achieved.

Option B is not true because SO3 will be decomposed into SO2 and O2 and can achieve equilibrium.

Option C is not true because both SO2 and O2 will react and make SO3 and can achieve equilibrium.

Option D is correct because SO2 requires O2 to react and form SO3. Since O2 is not present, thus reaction will not occur and equilibrium will not be achieved.

Option E is not true because SO3 can decompose into O2 and SO2 and can achieve equilibrium.

Sn4+(aq) + 2e− → sn2+(aq)which term best describes this reaction?ionizationneutralizationoxidationreduction
Yakvenalex [24]

Answer:

Reduction

Explanation:

Gaining electrons means reduction. When the electrons are on the reactant side of the reaction, they are added to the other reactant. This indicates that the Sn^4+ is gaining electrons and is therefore reduced (reduction).

Use the pull-down boxes to specify states such as (aq) or (s). If a box is not needed leave it blank. If no reaction occurs leav
babunello [35]

Answer:

H+  +  OH−  --> H2O

Explanation:

Hydrochloric acid is represented by the chemical formular; HCl. This is an ionic substance so in water it breaks apart into hydrohrn ions; H+ and chloride ions; Cl−. It is a strong acid, hence it completely dissociates.

Potassium Hydroxide is also an ionic substance it also breaks apart in water into potassium ions; K+ and hydroxide ions; OH−. It is a strong base, hence it completely dissociates.

The complete ionic equation for the reaction is given as;

H+  +  Cl−  +  K+  +  OH−  -->  K+  +  Cl−  +  H2O

The Hydrogen ion and the Hydroxide ions combine to form water.

The net ionic equation is given as;

H+  +  OH−  --> H2O

Cl- and K+ ions were cancelled out because they do not undergo any changes therefore are not part of the net ionic equation. They are referred to as spectator ions.

A solution of sodium hydroxide was titrated against a solution of sulfuric acid. How many moles of sodium hydroxide would react
jeka57 [31]

Answer:

2 mole of Sodium hydroxide reacts with 1 mole of Sulfuric acid

Explanation:

Write down the equation in the beginning with reactants and products:

NaOH + H₂SO₄ → Na₂SO₄ + H₂0

Now try to balance it. Try with Na first:

2NaOH + H₂SO₄ → Na₂SO₄ + H₂0

Na atoms are balanced. There are 6 Oxygen atoms on the right and 5 on the left. Balance by increasing the H₂O moles:

2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂0

Check if H atoms are also balanced. They are. That means our final reaction is:

2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂0

2 Moles of NaOH reacts with 1 mole of H₂SO₄

Ca+HCI—>CaCI2+H2, what is the reaction?
arsen [322]

Answer:

single replacement reaction

Explanation:

This is a kind of single replacement reaction where you switch either cations or anions. Here you switched Ca for H and produced Cacl2 and H2 gas by itself.
