Answer:
d.miscible
Explanation:
If two liquids are completely miscible, no interfacial tension exists between them.
Interfacial tension is the force of attraction between between the molecules of a fluid that are in contact. This tension forms thick skin at the interface.
In miscible liquids, in which one liquid completely dissolves in another, there is no interfacial tension.
Interfacial tension does not allow miscibility of fluids as the tension between the interface is too great.
- When there is a condition of no interfacial tension, two liquids are miscible.
- When there is immiscibility, interfacial tension exists between two fluids and this invalidates option A.
So, if two liquids are miscible, there is no interfacial tension between them.
Explanation:
Acids and alkalis both contain ions. Acids contain lots of hydrogen ions, which have the symbol H+. Alkalis contain lots of hydroxide ions, symbol OH-. Water is neutral because the number of hydrogen ions is equal to the number of hydroxide ions
Answer:
it stop burning because the gas surrounds itself
