Use bond energies to calculate the enthalpy change for the following reaction. h2(g) + co2(g) ⟶ h2o(g) + co(g)

For the given reaction, the enthalpy change calculated with bond energies is 36 kJ/mol.

Given the following balanced reaction:

H₂(g) + CO₂(g) → H₂O(g) + CO(g)     (1)

The enthalpy change () can be calculated with the next equation:

Where:

n and m are the stoichiometric number of moles of the reactants and the products, respectively          

and are the bond energies of the reactants and the products, respectively

For reaction (1), the enthalpy change is given by:

Therefore, the enthalpy change for the given reaction is 36 kJ/mol.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
