I need some help with net ionic equations. I can do single replacement, double replacement, etc., but I don't get stuff like gas forming-reactions or the trends when stuff like a strong acid and water are the reactants.
1. Moist sodium hydroxide reacts with carbon dioxide gas.
2. Rubidium permanganate is added to solid silver iodide.
Help please? Thank you!
I'm not sure of your general question. For the two questions posted, however,
1. NaOH(moist aq) + CO2 ==> Na2CO3 is a synthesis reaction.
2. RbMnO4 + AgI ==> is a redox reaction. I would expect the MnO4^- to oxidize I^- to I2 and MnO4^- to be reduced. In the dry state, however, I don't think any reaction will take place; i.e., the redox reaction will only occur in aq solution.
