Answer:
potassium and fluorine both react and form potassium fluoride.
Explanation:
Synthesis reaction:
It is the reaction in which two or more simple substance react to give one or more complex product.
General reaction:
A + B → AB
For example in given potassium and fluorine reaction both react and form potassium fluoride.
Chemical reaction:
K + F₂ → KF
Balanced chemical reaction:
2K + F₂ → 2KF
The oxidation state of potassium is +1 while the oxidation state of fluorine is -1. That's why one atom of potassium combine with one atom fluorine and form potassium fluoride.
Answer:
(c) 
Explanation:
The solubility product of a solid is the amount of solid dissociates into its respective ions in the solution. Thus more the value of the Ksp, the more is the salt soluble in the solvent.
So, Given that:-




The salt having highest value of Ksp is AgCN. So, it is most soluble.
Answer:
Explanation:
The attachment or (Bond) that resolves around the atoms of CI2 which is a covalent bond, yet energy is needed to destroy the bond and when new bonds are produced, energy is unleashed while the bond's development makes the molecule equilibrated. In short terms to basically break this bond energy is required and another terms energy is occupied and is the conclusion to your question (I tried my best) Energy is absorbed which is the result of what occurs.
