Answer : The correct option is, (D) CO₂, BCl₃, and Fe³⁺
Explanation :
According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.
(a) 
It is a Lewis-acid because it can accepts electron pairs.
(b) 
It is not a Lewis-acid because it can not accepts electron pairs but it is a base because it can donates and accept hydrogen ion.
(c) 
It is a Lewis-acid because it can accepts electron pairs because it has an incomplete octet and an empty 2p orbital.
(d) 
It is a Lewis-acid because it can accepts electron pairs.
Hence, the ions which behave as Lewis acids are, CO₂, BCl₃, and Fe³⁺
Carbon dioxide concentrations expected to increase because fossil fuel burning is expected to increase
Answer:
The modern model recognizes particles in the atom, whereas Dalton’s model does not.
Explanation:
The modern model considers the atom to consist of electrons, protons, and neutrons.
A is wrong. The modern model of the atom is widely accepted.
B is wrong. Dalton assumed that all atoms are identical. The modern model recognizes that there are isotopes of atoms.
D is wrong. The modern model explains emission spectra. Dalton's model does not.
