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?
Thank you! Very informative.
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?
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?
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?
