Input: Hydrogen
In inorganic chemistry, hydrides can also serve as bridging ligands that link two metal centers in a coordination complex. This function is particularly common in group 13 elements, especially in boranes (boron hydrides) and aluminium complexes, as well as in clustered carboranes.

What chemistry do hydrides serve as bridging ligands?
Output: inorganic chemistry

Input: Qing dynasty
Banner Armies were organized along ethnic lines, namely Manchu and Mongol, but included non-Manchu bondservants registered under the household of their Manchu masters. The years leading up to the conquest increased the number of Han Chinese under Manchu rule, leading Hong Taiji to create the Eight Han Banners (zh), and around the time of the Qing takeover of Beijing, their numbers rapidly swelled. Han Bannermen held high status and power in the early Qing period, especially immediately after the conquest during Shunzhi and Kangxi's reign where they dominated Governor-Generalships and Governorships across China at the expense of both Manchu Bannermen and Han civilians. Han also numerically dominated the Banners up until the mid 18th century. European visitors in Beijing called them "Tartarized Chinese" or "Tartarified Chinese". It was in Qianlong's reign that the Qianlong Emperor, concerned about maintaining Manchu identity, re-emphasized Manchu ethnicity, ancestry, language, and culture in the Eight Banners and started a mass discharge of Han Bannermen from the Eight Banners, either asking them to voluntarily resign from the Banner rolls or striking their names off. This led to a change from Han majority to a Manchu majority within the Banner system, and previous Han Bannermen garrisons in southern China such as at Fuzhou, Zhenjiang, Guangzhou, were replaced by Manchu Bannermen in the purge, which started in 1754. The turnover by Qianlong most heavily impacted Han banner garrisons stationed in the provinces while it less impacted Han Bannermen in Beijing, leaving a larger proportion of remaining Han Bannermen in Beijing than the provinces. Han Bannermen's status was decreased from that point on with Manchu Banners gaining higher status. Han Bannermen numbered 75% in 1648 Shunzhi's reign, 72% in 1723 Yongzheng's reign, but decreased to 43% in 1796 during the first year of Jiaqing's reign, which was after Qianlong's purge. The mass discharge was known as the Disbandment of the Han Banners (zh). Qianlong directed most of his ire at those Han Bannermen descended from defectors who joined the Qing after the Qing passed through the Great Wall at Shanhai Pass in 1644, deeming their ancestors as traitors to the Ming and therefore untrustworthy, while retaining Han Bannermen who were descended from defectors who joined the Qing before 1644 in Liaodong and marched through Shanhai pass, also known as those who "followed the Dragon through the pass" (; cong long ru guan).

When did Manchu ethnicity become important again in the Eight Banners?
Output: Qianlong's reign

Input: Napoleon
When he became First Consul and later Emperor, Napoleon eschewed his general's uniform and habitually wore the simple green colonel uniform (non-Hussar) of a colonel of the Chasseur a Cheval of the Imperial Guard, the regiment that often served as his personal escort, with a large bicorne. He also habitually wore (usually on Sundays) the blue uniform of a colonel of the Imperial Guard Foot Grenadiers (blue with white facings and red cuffs). He also wore his Legion d'honneur star, medal and ribbon, and the Order of the Iron Crown decorations, white French-style culottes and white stockings. This was in contrast to the gorgeous and complex uniforms with many decorations of his marshals and those around him.

What color stockings did Napoleon usually wear?

white
