Answer:

FeBr3 is the Lewis acid, and FeBr4-1 is the Lewis base.

Explanation:

A Lewis acid is any specie that has empty orbitals into which it can receive a lone pair of electrons.

A Lewis base is any specie that donates a lone pair of electrons to another to form a dative covalent bond.

If we look at the species listed in the options, FeBr3 is lone pair acceptor hence it is a Lewis acid while FeBr4- is a lone pair donor hence it is Lewis base.

Write 2 similarities and 2 differences between the digestive system of a Buffalo and humans
lutik1710 [3]

Answer:

The cow digestive system is not at all like the human digestive system. The main difference between the human digestive system and the cow's animal digestive system is simple: Cows have a stomach that consists of four compartments, commonly referred to as four stomachs. Cows spend the better part of the day eating, swallowing and regurgitating their food, and chewing it again before final digestion. Because a cow's teeth mostly grind their food, cows use their tongues – which is why they are so long – to help them gather and grasp grass for pinching off between their incisors and dental pad at the front part of their mouths.
