Answer:
HCl is a Bronsted acid, dissociates partially or completely with the release of H+ dissociating as H+ and Cl-.
BF_3 is a Lewis acid because it has an incomplete octet and an empty 2p orbital, so it can accept a lone pair. It is clearly not a Bronsted acid as it does not have a H+ to release on dissociation.
CCl_3 Lewis base
-H Lewis base
CH_2O Bronsted base
CH_3Cl Bronsted acid
-OCH_3 Lewis base
NH_3 is a Lewis Base:, N has a a lone pair which it can donate to a Lewis acid like BF3.
Explanation:
The Brønsted-Lowry theory describes acid-base interactions in terms of proton transfer between chemical species. A Brønsted-Lowry acid is any species that can donate a proton, H+, and a base is any species that can accept a proton. As for chemical structure, this means that any Brønsted-Lowry acid must contain a hydrogen that can be dissociated as H+. To accept a proton, a Brønsted-Lowry base must have at least one solitary pair of electrons to form a new bond with a proton.
Answer:
3 moles of oxygen at STP will occupy a volume of 3×22. 4=67. 2 L.
Explanation:
Answer:
D
Explanation:
Process of elimination. There is more than just water vapor in a vape so it can't be D, it isn't a cigarette so it can't be B, and A is just clearly not the answer haha.
<span>To account for the hexavalency in SF6 one electron each from 3s and 3p orbitals is promoted to 3d orbitals as shown in fig.1.27(b). These six orbitals get hybridised to form six sp3d2hybrid orbitals. Each of these sp3d2 hybrid orbitals overlaps with 2p orbital of fluorine to form S-F bond.
The answer is S(sp3d2)- F(p)</span>
