Homework Help: chemistry

Posted by Anonymous on Sunday, October 16, 2011 at 10:04pm.

The synthesis of urea by Frederich Wöhler in 1825 began the decline of the idea that "organic" chemicals could only be made by living organisms as part of their biological processes.

AgOCN(aq) + NH4Cl(aq) → AgCl(s) + NH2CONH2(aq)

If you perform this reaction and collect the following table of data, in which trial(s) is NH4Cl clearly the limiting reactant?

Trial mL AgOCN mL NH4Cl mass AgCl
1 10.4 mL 100.0 mL 4.9 g
2 20.2 mL 98.9 mL 10.1 g
3 30.0 mL 101.1 mL 20.6 g
4 40.2 mL 99.8 mL 30.2 g
5 50.1 mL 100.5 mL 30.1 g
6 60.2 mL 100.3 mL 30.2 g

The mL of AgOCN and NH4Cl are the initial amounts used, the mass of AgCl is how much was recovered from the reaction. (Hint: You do not need to do any calculations to answer this question.)
