Answer:

Explanation:

use the equation

moles = mass/mr

=19.9/79.5

=0.250moles of CuO

then do the same for

H = 2.02/1

=2.02

so CuO is the limiting reagent because there is less amount of it.

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⁻

Consider the following reaction:

mestny [16]

Equation: NH4HS(s) <=> NH3 (g) + H2S(g)

Kc = [NH3]eq[H2S]eq; where eq subscripts are used to indicate that those are the concentrations at equilibrium

Kc= 0.272 * 0.365 =0.09928
