Why might the amount of copper produced be less than 100% of the expected amount? check all possible reasons. there are impurities in the substances. the reaction might not go to completion. the amount of one of the reactants might be measured incorrectly. the molar ratio may not be correct. the expected amount might be based on measurements with error.

What is limiting reactant? with examples

Marcel just purchased 1.69 grams of iron fillings in order to make living putty for his 6 year old niece. how many moles of iron are made in his sample?

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
