The balanced equation is

Cl₂ + SO₂ +2H₂O ⟶ 2Cl⁻ +SO₄²⁻ + 4H⁺

This is a redox reaction, so I will balance it using the ion-electron method.

Step 1. Write the skeleton equation.

Strip the equation of H⁺ and H₂O (these come back in during the balancing procedure). We get

Cl₂ + SO₂ ⟶ Cl⁻ +SO₄²⁻

Step 2: Separate the skeleton equation into two half-reactions.

Cl₂ ⟶ Cl⁻

SO₂ ⟶ SO₄²⁻

Step 3: Balance all atoms other than H and O.

Cl₂ ⟶ 2Cl⁻

SO₂ ⟶ SO₄²⁻

Step 4: Balance O.

Add enough H₂O molecules to balance O,

Cl₂ ⟶ 2Cl⁻

SO₂ + 2H₂O ⟶ SO₄²⁻

Step 5: Balance H.

Add enough H⁺ ions to balance H.

Cl₂ ⟶ 2Cl⁻

SO₂ + 2H₂O ⟶ SO₄²⁻ + 4H⁺

Step 6: Balance charge.

Add electrons to the side that needs more negative charge.

Cl₂ + 2e⁻ ⟶ 2Cl⁻

SO₂ + 2H₂O ⟶ SO₄²⁻ + 4H⁺ + 2e⁻

Step 7: Add the two half-reactions.

The balanced equation is

Cl₂ + SO₂ + 2H₂O ⟶ 2Cl⁻ + SO₄²⁻ + 4H⁺

In which system does a spontaneous redox reaction produce electrical energy?

Vladimir [108]

Had to look for the options and here is my answer.
When we say that a redox reaction is spontaneous, this would mean that there is a formation of positive voltage across the electrodes of a voltaic cell. Therefore, the system that this kind of reaction produces electrical energy is in a GALVANIC CELL. Hope this helps.

The Ka for acetic acid (HC2H3O2) is 1.80 x 10-5 . Determine the pH of a 0.0500mol/L acetic acid solution.

TiliK225 [7]

Answer:

pH = 3.02

Explanation:

Acetic Acid is a weak acid (HOAc) that ionizes only ~1.5% as follows:

HOAc ⇄ H⁺ + OAc⁻.

In pure water the hydronium ion concentration [H⁺] equals the acetate ion concentration [OAc⁻] and can be determined* using the formula [H⁺] = [OAc⁻] = SqrRt(Ka·[acid]) = SqrRt(1.8x10⁻⁵ x 0.0500)M = 9.5x10⁻⁴M.

By definition, pH = -log[H⁺] = -log(9.5x10⁻⁴) = 3.02

______________________________________________________

*This formula can be used to determine the [H⁺] & [Anion⁻] concentrations for any weak acid in pure water given its Ka-value and the molar concentration of acid in solution.

Use the following balanced reaction to solve 1-3:

tino4ka555 [31]

Answer:

1.96g H2

Explanation:

P4 = 123.9g/mol

H2 = 2.02g/mol

$\frac{20g P_{4} }{1}$ * $\frac{1 mol P_{4} }{123.9g}$ * $\frac{6 mol H_{2} }{1 mol P_{4} }$ * $\frac{2.02g H_{2} }{1 mol H_{2} }$ = 1.96g H2
