PLEASE QUICK HELP Use bond energies to calculate the enthalpy change for the following reaction.
H2(g) + CO2(g) — H2O(g) + CO(g)

PLEASE ANSWER IN A TABLE:)

Is there any other information that there is to tell you I would love to help Is there any other information that there is to tell you I would love to help

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
