Bismuth chloride $(BiCl_3)$, on hydrolysis, yields a white precipitate of
Nitrogen is unreactive at room temperature but becomes reactive at elevated temperatures (on heating) or in the presence of catalysts. In nitrogen molecules, there is extensive delocalization of electrons.
In crystal lattice, size of the cation is larger in a tetrahedral hole than in an octahedral hole. The cations occupy more space than anions in crystal packing.
Electrons are ejected from a certain metal when either blue or violet light strikes the metal surface. However, only violet light causes electron ejection from a second metal. The electrons in the first metal require less energy for ejection.
Azolla pinnata is used as a biofertilizer in rice cultivation. Azolla performs nitrogen fixation with the help of symbiotic bacterium Bacillus sp.
Alpine forests consist of dwarf shrubs mainly of junipers, silver firs and rhododendrons. Alpine forests occur in the Himalayas above the altitude of 3500 metres.
Acetylcholine participates in the nerve impulse transmission across a synapse. Acetylcholine is secreted by adrenergic fibres.
A special line will be seen for a $2p_x \to 2p_y$ transition. Energy is released in the form of waves of light when the electron drops from $2p_x$ to $2p_y$ orbital.
