Answer: 75.7 % yield
Explanation:
The balanced chemical equation is:
According to stoichiometry :
68.2 g of will require = 64 g of
Thus 7.5 g of will require = of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 68.2 g of give = 96 g of
Thus 7.5 g of give = of
% yield=
Thus 75.7 % yield is there.
Answer:
neck
Explanation:
through the neck and opening of the thermos, where there is no vacuum.. hence heat is easily transmitted resulting into heat loss
