Answer:
c. fluorine
Explanation:
A single replacement reaction is defined as the chemical reaction in which a strong molecule replaces the weak molecule from a compound.
In a single replacement reaction, the chloride ion in NaCl can be replaced by fluorine and gives Sodium fluoride as fluorine (F) is stronger than chlorine (Cl) and from other given molecules also. So the single replacement reaction between NaCl and F will be:
NaCl + F2 => NaF + Cl2
Hence, the correct answer is "c. fluorine".
The dust particles in the water can be helped to settle down faster by Alum.
So, your answer is option B. Alum.
Hope this helps!
True, this is because they are too small to be studied as if they were an animal, plant, or geological formation such as a rock or crystal.
Lithium, sodium, potassium, magnesium, calcium, barium, boron, aluminum, nitrogen, phosphorus, sulfur, fluorine and xenon are all examples of elements that react with oxygen. Oxygen reacts with other elements but those reactions are relatively mundane.
higher Ka value= stronger acid
stronger acids have weaker conjugate bases, so the acid with the strongest conjugate base would be acetic acid
