Answer:
NH3
Explanation:
In solution, they are in equilibrium. NH4+ acts as a bronsted Lowry acid and donates an H to become NH3, and NH3 acts as a bronsted lowry base and accepts an H. In this pair, NH3 is a weak base, which gets its basic character due to the presence of lone pair of nitrogen and its ability to donate it.
Answer: non metal
Explanation:
Nonmetals are dull, possess high ionization energies and electronegatives and are typically poor electricity conductors as they're insulators.
Non metals are also brittle and possess low melting point. Therefore, with the explanation, the sample is most likely a non metal.
Answer:
Option (3)
Explanation:
Ductility of a substance is defined as the property by which a substance can be hammered and change its form into thin, stretched wires. In simple words, the ductile materials can be drawn into thin wires. Some of the examples of ductile substances are gold, copper and silver.
The rocks also have this property which means that they have the capacity to get deformed into enormous strains in the absence of large scale fracturing.
Thus, the correct answer is an option (3).
