Hey guys, I just need some help with my Chemistry (Gr.12) homework. It's the last unit and I'm kind of lost. If I could possibly get the steps and answers to this question, that would greatly help me.



Determine whether each of the following reactions is a redox reaction?



2NaHCO3 -> Na2CO3 + H2O + CO2



2HBr + Ca(OH)2 -> CaBr2 + 2H2O



PCl5 -> PCl3 + Cl2



Best answer will be given, thank you very much
