Suggest why you were told to remove the beaker from balance before mixing the two reactants.

是(为什么你被告诉在混和2个反应物之前先从天平上移去烧杯)吧
不知道翻译对不对,对的话应该是天平上不能用来反应,天平是用来平衡或测物体的质量的.

为什么你被告知要在混合两种反映物前从天平上移走烧杯

建议，为什么要告诉你在把两种反应物质混合之前，先把烧杯从天平上拿下来？

解释为什么你被告知在混合两个反应物前要把烧杯从天平上拿开

把两种反应剂混合之前，要标明为什么要把烧杯从天平上拿下来。

just guessing...>.<
maybe after mixing the two reactants, chemical reaction may result in physical reaction such as evaporation, which will eventually lead to weight loss of the solution inside the beaker and produce error in statistics...
