Answer:
The answer to your question is: Iron oxidizes and Copper reduces
Explanation:
An element oxidizes when it loses electrons
An element reduces when it gains electrons
Then
Fe ⇒ Fe⁺² Now, is more positive, it loses electrons
Cu⁺² ⇒ Cu Now, is more negative, it gains electrons
Iron oxidizes and Copper reduces
Answer:
The concentration and pKa of an acid and its conjugate base can limit the buffering capacity of a molecule.
Explanation:
A buffer is an acid and its conjugate base and the quality of it depends on its buffer capacity. This buffer capacity is the resistance to change the pH of the solution when strong acids or bases are added. The buffer capacity is related to the buffer concentration, the concentration of the acid end its conjugate base. Also, every acid has a pKa and the buffer capacity is at its maximum at the pKa value and can buffer the solution between ± 1 the pKa value.
Answer:
CH2O is formaldehyde a covalent compound and its intermolecular forces are week
KCl is an ionic compound formed by electrostatic force of attraction between positive and negative charge. Ionic compounds also exists in three dimensional crystal lattic that is why intermolecular forces in KCl is stronger.
Moreover melting point of KCl is higher than CH2O
