Determine ΔrG° for the following reaction:

Fe2O3(s)+3CO(g)→2Fe(s)+3CO2(g)

Use the following reactions with known ΔrG° values:

2Fe(s)+32O2(g)→Fe2O3(s), ΔrG° = - 742.2 kJmol−1

CO(g)+12O2(g)→CO2(g), ΔrG°= - 257.2 kJmol−1

Express your answer using one decimal place.

2pos suppose an object in free fall is dropped from a building. its starting velocity is 0 m/s. ignoring the effects of air resistance, what is the speed (in m/s) of the object after falling 3 seconds? give your answer as a positive decimal without units. answer here

If you chip a tooth, most likely you will go to the dentist to have the missing material filled in. currently the material used to fill in teeth is a polymer that is flexible when put in, yet is hardened to the strength of a tooth after irradiation with blue light at a wavelength of 461 nm. what is the energy in joules for a photon of light at this wavelength?
