Balance equations:
Aqueous solutions of Cu(NO3)2, Na2CO3 are mixed and produce a blue precipitate of CuCO3.
I wrote Cu(NO3)2 + Na2CO3 --> 2CuCO3
What does the blue mean and how should i express that?
or am I right with what I have?
Another balancing equation has to deal with neutralization:
aqeous solutions of NaOH and H2SO4 are mixed. The neutralization of water is formed with the evolution of heat.
How do I go about balacing this one?
