Answer:
Bronsted-Lowry acid
Explanation:
Bronsted-Lowry Base -
According to Bronsted-Lowry theory of acids and bases:
Acids are those substances which donate proton in the solution whereas bases are those substances which accept proton in the solution.
Consider an example,
HCO3- behave as base as it accepts proton in the reaction whereas HOH behaves as acid as it releases proton.
According to Lewis theory of acids and bases:
Acids are electron acceptor and bases are electron donar. Acids are generally electron deficient species whereas Lewis are chemical species having lone pair of electrons.
For example, AlCl3 is behave as Lewis acid because of being electron deficient species.
NH3 is a Lewis base because of presence of lone pair of electrons.
Therefore, among given options, Bronsted-Lowry acid is the correct option.
Given :
The atomic weight of copper is 63.5 gm.
To Find :
The total number of gram atoms and number of atoms present in 100 gram of copper.
Solution :
We know, 1 gram atom is equal to mass of one mole of copper i.e. 63.5 gm.
So, number of gram atom in 100 gram of copper is :
n = 100/63.5
n = 1.57 gram atom
Now, number of atoms on gram atom is :
Therefore, total number of gram atoms and number of atoms present in 100 gram of copper is 1.57 gram atom and .
Hence, this is the required solution.
