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:
Friction is "a force which opposes relative motion" while kinetic energy is the "energy an object has associated with its motion." Frictional work will reduce an object's kinetic energy if it opposes the current speed
Explanation:
Molecular solids do not ionize into several particles while ionic solids do (to some extent). Since Freezing-point depression is a colligative property, caused by the presence of particles of non-volatile solute (and not on their chemical nature), ionic solids have a multiplicative effect on the change in temperature per unit - i.e. the van't hoff constant, i<span>.
