why don't reactions give us a 100 percent yield?

i dont give a f***
give the meaning and answer of kinds of fraction percent ratio proportion decimals inverse comparing ratios converting rartios rate
Mixing 80 liters of 15% solution and 520 liters of 90% solution will give 600 liters of 80% solution.
365$ give or take :)
The yield is 82,45 %.
Percentage yield is worked out as (amount you got/ amount you could have got) x 100 You should do the calculation in moles so weigh your compound, work out its molar mass and divide the mass by the molar mass to get number of moles. Then you have to work out your maximum theoretical yield - work out how many moles of reactant you started with and check the stoichiometric ratio from your balanced equation to find how many moles you expected to get. In organic reactions a yield of 60% or so is normal. The more steps you went through in your preparation, the lower you would expect your yield to be. Many reactions just do give a low yield anyway, because they are at equilibrium rather than going to completion, like the Haber process.
cows yield milk
Vitamins are not used as energy sources, they are not oxidized. They take part in many reactions that yield energy tough (like the B group)
No. They result in salts. By the way I dont mean cooking salt.
Exothermic reactions are reactions that give off heat.
Yield.
reactions with acid often give off
Why did the deli give way to the street sign? Y + deli = yield.
Such reactions are called Exothermic reactions.
if you speak of %yield meaning experimential yield over theorietical yield then divide the 2 numbers and multiply by 100 give you the ans
Yield means to give way. It can also mean that the land yields wheat and barley.
