Answer:
B
Explanation:
because every Chinese shar-pei has wrinkled skin.
H₃As is stronger acid than H₂Se.
The H-A bond strength typically determines the size of the "As" atom in an acid; the smaller the "As" atom, the stronger the H-A bond. In the Periodic Table, the atoms get bigger and the bonds get weaker as you advance down a row, strengthening the acids.
<h3>What is acid?</h3>
Any molecule or ion that may donate a proton—a Brnsted-Lowry acid—or establish a covalent bond with a pair of electrons—a Lewis acid—is regarded as an acid. The first class of acids are the Brnsted-Lowry acids, often known as proton donors.
The compound is referred to chemically as lysergic acid diethylamide, or LSD as it is more commonly known. Using it may lead you to have a distorted perception of reality and objects because it has a potent hallucinogenic effect. LSD has an effect known as tripping.
Aqueous solutions of acids with a pH lower than 8 are frequently referred to as "acids," even though the term "acid" technically only refers to the solute.

- Standard reduction potential of Ag/Ag⁺ is 0.80 v and that of Cu⁺²(aq)/Cu⁰ is +0.34 V.
- The couple with a greater value of standard reduction potential will oxidize the reduced form of the other couple.
Ag⁺ will be reduced to Ag(s) and Cu⁰ will be oxidized to Cu²⁺
Anode reaction: Cu⁰(s) → Cu²⁺ + 2 e⁻ E⁰ = +0.34 V
Cathode reaction: Ag⁺(aq) + e → Ag(s) E⁰ = +0.80 V
Cell reaction: Cu⁰(s) + 2 Ag⁺(aq) → Cu⁺²(aq) + 2 Ag⁰(s)
E⁰ cell = E⁰ cathode + E⁰ anode
= 0.80 + (-0.34) = + 0.46 V
