The bond enthalpy in no is 632 kj/mol and that of each no bond in no2 is 469 kj/mol. explain the difference in bond enthalpies between the two molecules.

1. no has a double bond while in no2 the bonds are equivalent due to resonance.
2. no has a single bond while in no2 the bonds are equivalent due to resonance.
3. double bonds always have a larger bond enthalpy than single bonds.
4. the bond type does not explain the dif- ference.

Plzz a sample of table sugar (sucrose, c12h22o11) has a mass of 7.801 g. ● a) calculate the number of moles of c12h22o11 in the sample b) calculate the number of moles of each element in c12h22o11 (number of moles of c, number of moles of h & number of moles of o) in the sample. (use your answer from part a as your starting point.) show your work and highlight your final answer. calculate the number of atoms of each element in c12h22o11 (number of atoms of c, number of atoms of h & number of atoms of o) in the sample. (use your answers from part b as your starting for each element.) show your work and highlight your final answer.
