You should choose the category this question belongs to from these categories: History, Science, Social Science, Fine Arts, Literature. You can only choose one category, so if in doubt, please choose the closest match.
PROBLEM: Ninhydrin forms a Schiff base with this chemical, resulting in a hue known as Ruhemanns purple. The Birch reduction takes place in a liquid substrate of it, the reason it is common in methamphetamine labs. The Kjeldahl method uses this molecule as an end-product to measure the amount of nitrogen in a sample, and it is oxidized in the first step of a nitric acid forming procedure, the Ostwald process. For 10 points, name this weak base found in fertilizers, formed by combining hydrogen and nitrogen in a three-to-one ratio in the Haber process.

SOLUTION: Science

PROBLEM: A quantity analogous to this effect in electrodynamics is called the Christofel voltage, while large motions restored by it were found by Carl Rossby. The Etvs effect accounts for its vertical component, and Buys-Ballot's Law is a result of this effect in areas of different pressure. Present only in non-inertial frames of reference, this effect was also considered when Laplace derived his tidal equations, and it influences the rotation of sunspots and the circulation of the atmosphere. Proportional to the cross product of the angular frequency and velocity, this is, FTP, which force that describes the tendency of a body to drift away from its course due to the Earth's rotation

SOLUTION: Science

PROBLEM: One result of this war was a revolution led by the MNR Party, and it ended with a mediation led by Carlos Lamas. This war saw a massive siege of Fort Boqueron. It began with the Battle of Pitiantuta, and one decisive battle saw the defeat of General Penaranda. The defending country was led by Jose Estigarriba and advised by numerous Russian migrs such as General Belaieff. The attacking country, led by President Salamanca and General Hans von Kundt, had warplanes and tanks, but these proved ineffective against the guerilla tactics of Paraguay. For ten points, name this 20th century war where Bolivia failed to conquer the namesake region.
