Question

Use the reaction and bond information to answer the question.

H2 + CO2 → CH2O2

Reactant bond energies: H–H is 432 kJ/mol, C=O is 799 kJ/mol

Product bond energies:
C–H is 413 kJ/mol, C=O is 745 kJ/mol
C–O is 358 kJ/mol, O–H is 467 kJ/mol

How much energy will be given off by the products?

1,570 kJ

1,983 kJ

1,238 kJ

1,516 kJ

Answer 1

`\\ \bull\tt\longmapsto 413+745+358+467`

`\\ \bull\tt\longmapsto 1983KJ`
