Broccolini (original Japanese: ãã­ãã³ãªã¼ã) is a green vegetable similar to broccoli but with smaller florets and longer, thin stalks.Often misidentified as young broccoli, it is a hybrid of broccoli and kai-lan, both cultivar groups of Brassica oleracea.rom Wikipedia, the free encyclopedia. Broccolini (original Japanese: ãã­ãã³ãªã¼ã) is a green vegetable similar to broccoli but with smaller florets and longer, thin stalks. Often misidentified as young broccoli, it is a hybrid of broccoli and kai-lan, both cultivar groups of Brassica oleracea.
A 100% yield means that no product has been lost, while a 0 per cent yield means that no product has been made. There are several reasons why the percentage yield of a product might be less than 100 per cent, including loss when: 1  Filtering. 2  Evaporating. 3  Transferring liquids. 4  Not all reactants react to make product.
The percent yield is defined as. The predicted yield is determined by the masses used in a reaction and the mole ratios in the balanced equation. This predicted yield is the ideal. It is not always possible to get this amount of product. Reactions are not always simple. There often are competing reactions.
