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.
Rating Newest Oldest. Best Answer: Having a low percent yield means that you received much less product than you expected to get. The theoretical yield predicts how much product you're supposed to make, but by experimental error and unavoidable error, this number will decrease. Lower percent yields are common, because rarely will an experiment proceed perfectly. There are just too many outside factors to distract the process.
