Cola-flavored soda: 2. 6 -Acidic

cranberry juice: 2. 9  -Acidic

dish soap: 7. 3  -Basic

pickle juice: 5. 5  -Acidic

seawater: 8. 0 -Basic

lye soap: 13. 0. -Basic

<h3>What is pH?</h3>

pH value tells us about the acidity and basicity of any solution. pH means potential hydrogen.

The pH scale is counted from 0 to 14 in which 7 is neutral and the value of pure water.

Below 7 are all acids and the above 7 are all basic.

Thus, all acidic substances are Cola-flavored soda: 2. 6, pickle juice: 5. 5, cranberry juice: 2. 9.

<em>Answer:</em>

  • The protein is an organic compound which is made up of the amino acids methionine, arginine, and leucine etc. 

<em>Explanation:</em>

  • Most of the amino acid are linked with others amino acid through peptide linkage to form proteins. The peptide bond is formed between the two amino acid involving carboxylic and amino group.
  • The proteins produce by this way may be simple, conjugated and derived proteins.

For the following electron-transfer reaction:
creativ13 [48]

Answer:

1. The oxidation half-reaction is: Mn(s) ⇄ Mn²⁺(aq) + 2e⁻

2. The reduction half-reaction is: Ag⁺(aq) + 1e⁻ ⇄ Ag(s)  

Explanation:

Main reaction: 2Ag⁺(aq) + Mn(s) ⇄ 2Ag(s) + Mn²⁺(aq)

In the oxidation half reaction, the oxidation number increases:

Mn changes from 0, in the ground state to Mn²⁺.

The reduction half reaction occurs where the element decrease the oxidation number, because it is gaining electrons.

Silver changes from Ag⁺ to Ag.

1. The oxidation half-reaction is: Mn(s) ⇄ Mn²⁺(aq) + 2e⁻

2. The reduction half-reaction is: Ag⁺(aq) + 1e⁻ ⇄ Ag(s)  

To balance the hole reaction, we need to multiply by 2, the second half reaction:

Mn(s) ⇄ Mn²⁺(aq) + 2e⁻

(Ag⁺(aq) + 1e⁻ ⇄ Ag(s)) . 2

2Ag⁺(aq) + 2e⁻ ⇄ 2Ag(s)  

Now we sum, and we can cancel the electrons:

2Ag⁺(aq) + Mn(s) + 2e⁻ ⇄ 2Ag(s) + Mn²⁺(aq) + 2e⁻
