43 inHg = 43 inHg*2.54cm/in = 109.22cmHg * 10 mm/cm = 1092.2 mmHg
14.7 psi = 760 mmHg
1092.2mmHg * 14.7psi / 760 mmHg = 21.13 psi
Answer: option D. 21.13 psi
Answer:
Adduct, donate, accept
Explanation:
Lewis acids are those having suitable vacant orbital for electron acceptance and forming a covalent bond with an electron rich species. Example:
(B has vacant 2p orbital for electron acceptance)
Lewis bases are those having energetically available unshared electrons that can be donated to an electron deficient species and form a covalent bond. Example:
(N has energetically available lone pair)
So, product of Lewis acid-base reaction is an adduct (
) where a new covalent bond is formed between B and N.
