In chemistry, an amphoteric compound is a molecule or ion that can react both as an acid as well as a base. Many metals (such as copper, zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. Amphoterism depends on the oxidation states of the oxide. AlO is an example of an amphoteric oxide.
can a compound be both an acid and a base?

The Andorran government imposes no visa requirements on its visitors and only requires a passport or European Union national identity card for entrance. However, since the country is only accessible via the Schengen countries of Spain or France, entrance is not possible without entering the Schengen area first and the Schengen visa rules can therefore be regarded to apply de facto. Because Andorra is not part of the Schengen area, a multiple entry visa is required to re-enter the Schengen area when leaving Andorra. Foreign visitors looking to stay in Andorra more than 90 days require a residence permit.(2)
can i go to andorra with schengen visa?

The Hobbit is a film series consisting of three high fantasy adventure films directed by Peter Jackson. They are based on the 1937 novel The Hobbit by J.R.R. Tolkien, with large portions of the trilogy inspired by the appendices to The Return of the King, which expand on the story told in The Hobbit, as well as new material and characters written especially for the films. Together they act as a prequel to Jackson's The Lord of the Rings film trilogy. The films are subtitled An Unexpected Journey (2012), The Desolation of Smaug (2013), and The Battle of the Five Armies (2014).
are all three hobbit movies in one book?
