Write a balanced half-reaction for the reduction of gaseous oxygen to aqueous hydrogen peroxide in basic aqueous solution. Be su
Vesna [10]

Answer:

Balanced half-reaction: O_{2}(g)+2H_{2}O(l)+2e^{-}\rightarrow H_{2}O_{2}(aq.)+2OH^{-}(aq.)

Explanation:

Balanced half-reaction for the reduction of gaseous oxygen to aqueous hydrogen peroxide in basic solution should be written in the following step-by-step manner:

Half-reaction: O_{2}(g)\rightarrow H_{2}O_{2}(aq.)

Balance H and O in basic medium: O_{2}(g)+2H_{2}O(l)\rightarrow H_{2}O_{2}(aq.)+2OH^{-}(aq.)

Balance charge: O_{2}(g)+2H_{2}O(l)+2e^{-}\rightarrow H_{2}O_{2}(aq.)+2OH^{-}(aq.)

Balanced half-reaction: O_{2}(g)+2H_{2}O(l)+2e^{-}\rightarrow H_{2}O_{2}(aq.)+2OH^{-}(aq.)

The concentration of hydroxide ions is less than the concentration of hydronium ions for acidic solutions. True False
wolverine [178]

Answer:

True

Explanation:

It's true because the pH is a measure of how basic or acid a solution is. In an acidic medium, the pH scales goes from 0 to 7. While in a basic medium goes from 7 to 14. The lower the pH value of the most acid the solution is.

1. The expression pH = -log(molar concentration of hydronium) allow to calculate the pH of a solution.

2. On the other hand, the expression pOH = -log(molar concentration of hydroxide) allow to determine the pOH of a solution.

The values of pH and pOH always obey the following expression:

pH + pOH = 14

Thus if for instance the pH becomes smaller the pOH must become bigger in order to fulfill the equation. Which means that the concentration of hydronium ions is greater than the hydroxide concentration.

For example, in an acidic medium:

if pH= 3, pOH= 11

In this case the molar concentration of hydronium is 0,001M. And the molar concentration of hydroxide ions is just 0,00000000001M.

Identify the Following as either Alkanes, alkynes or alkenes
puteri [66]

Answer:

The answer to your question is below

Explanation:

To solve this problem use the general formulas for Alkanes, Alkenes, and Alkynes.

Alkanes           Cn H(2n + 2)

Alkenes           Cn H (2n)              "n" is the number of Carbons

Alkynes            Cn H (2n - 2)

a) CH₄             C₁ H 2(1) +2   = C₁H₂ + ₂ = CH₄       Alkane

b) C₂H₄            C₂ H₂(₂)                                           Alkene

c) C₃H₆             C(₃) H₂ (₃)                                        Alkene

d) C₂H₂            C₂ H₂(₂) - 2  = C₂H₄ - ₂ = C₂H₂        Alkyne

e) C₁₀H₂₂          C₁₀ H₂(₁₁)                                          Alkene
