Acid/base, precipitation, redox, or none: . 1. ba(clo3)2(s) > bacl2(s) + 3o2(g). 2. cao(s) +co2(g) > caco3(s)

There are two equations given in the question. The type of reaction shown can be easily judged, if one takes a closer look at the equations.

1. Ba(ClO3)2(s) > BaCl2(s) + 3O2(g) Redox

2. CaO(s) +CO2(g) > CaCO3(s) None.

I hope that this is the answer that you were looking for and the answer has actually come to your desired help.
