Hello,
I have this problem from a general chemistry guide but I have no idea what "cs" means. I already look online but I can't find an acronym that makes sense with this one.
Can someone please let me know what does it mean?
This is the problem
CS is positive for the following reaction:
a) 2H2(g) + O2(g)---> 2H2O(g)
b) 2NO2(g)--->N2O4(g)
c) CO2(g)--->CO2(s)
d) BaF2(s)-->Ba2+(aq) + 2F-(aq)
e) 2Hg(l) + O2(g)-->2HgO(s)
thanks in advance
