Bitter taste, high pH, and caustic Bitter are the characteristics of base.
<h3>What are the characteristics of base?</h3>
Bases have bitter taste, soapy feel, turn red litmus paper blue. Bases are substances that contain metal oxides or hydroxides. Its pH is higher than 7 up to 14.
So we can conclude that bitter taste, high pH, and caustic Bitter are the characteristics of base.

Answer:
2 KF ₍s₎ → F₂ ₍g₎ + 2 K ₍s₎
Explanation:
Chemical Formula of Potassium Fluoride = KF
Chemical Formula of Fluorine Gas = F₂
Chemical Formula of Solid Potassium = K
Step 1: Write the unbalance chemical equation,
KF → F₂ + K
Step 2: Balance Fluorine Atoms;
As there is one fluorine atom on left hand side and two fluorine atoms on right hand site therefore, to balance them multiply KF on left hand side by 2 i.e.
2 KF → F₂ + K
Step 3: Balance Potassium Atoms;
As there are two potassium atoms on left hand side and one potassium atom on right hand site therefore, to balance them multiply K on right hand side by 2 i.e.
2 KF → F₂ + 2 K
Step 4: Assign Physical states as,
2 KF ₍s₎ → F₂ ₍g₎ + 2 K ₍s₎
Becouse melting point and cooling point are two opposite things one is 100degrees nd other 0degrees
