The characteristics of two different types of reactions are shown below: Reaction A: Protons are gained or lost by the atom of an element.
Reaction B: Electrons are lost by the atoms of an element.

Which statement is true about the two reactions?
- Valence electrons are not involved in both Reaction A and Reaction B.
- Valence electrons are involved in Reaction B but not in Reaction A.
- Valence electrons are involved in both Reaction A and Reaction B.
- Valence electrons are involved in Reaction A but not in Reaction B.

h let me think

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

58750.08068 is the answer i think

the dissolution of polymer can be thermodynamically described in 2 steps.
