Question

Acid/base, precipitation, redox, or none:. 1. Ba(ClO3)2(s) ----> BaCl2(s) + 3O2(g). 2. CaO(s) +CO2(g) ----> CaCO3(s)

Answer 1

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.
