Urea: (NH2)2CO 1. Which bonds in the molecule are polar and which are nonpolar? 2. What is the most polar bond in the molecule?

General Chemistry
Thank you! Very informative.

General Chemistry
2Fe2O3 + 3C > 4Fe + 3CO2 If 6.2 mol of Fe2O3 is used, what amount of C is needed, and what amounts of Fe and Co2 are produced?

General Chemistry
CaO + 2NH4Cl > 2NH3 + H2O + CaCl2 If 112 g of CaO and 224 g of NH4CL are mixed the theoretical yield of NH2 is 68.0 g. If only 16.3 g of NH3 is actually obtained, what is the percent yield?

General Chemistry
An unknown compound has a formula of CxHyOz. You burn 0.1523 g of the compound and isolate 0.3718 g of CO2, and 0.1522 g of H2O. What is the empirical formula of the compound? If the molar mass is 72.1 g/mol what is the molecular formula?
