percentage yield=actual yield *100/ predicted yield.
Yields in most of the reactions are never 100 % due to some error or mistakes,like while transfering one liquid into another container some amount will be left,sometimes not all the reactant react to form the product, it depend on the limiting reagent,sometimes there are side reactions which can complicate the reactions,many reactions do not go to completion due to equilibrium .In many cases the amount which is actually produced is very less than the yield calculated according to the theory, so the above statement is false

In the carbon cycle, combustion reactions produce atmospheric oxygen. True False The empirical formulas for H2O, H2O2, NH3, N2H4, C12H22O11, and Al2Cl6 are H2O, HO, NH3, NH2, C12H22O11, and AlCl3, respectively. True False The combustion reaction of hydrocarbons, in the presence of excess oxygen, will produce carbon monoxide and water. True False Stoichiometry of a chemical reaction refers to the quantitative relationships between the amounts of reactants and products involved in the reaction. True False The percent composition of a...
