Okay, I need some guidance.
I've tried googling some answers to this question and nothing has really helped me. It's kind of a common sense question, perhaps?
However, my common sense of chemistry reactions is quite low. I am wondering if there is a trick to questions like these:
"Identify the solid formed from the reaction between Mg(NO3)2 and Na2SO4 in aqueous solution. Write ""no reaction"" if no precipitate is formed."
"Identify the solid formed from the reaction between BaS and PbNO3 in aqueous solution. Write ""no reaction"" if no precipitate is formed."
"Identify the solid formed from the reaction between MgCl2 and NH4OH in aqueous solution. Write ""no reaction"" if no precipitate is formed."
How do I go about answering these? My first step would be to write down the products and reactants in an equation, correct? But how do I KNOW if one is aq, l, g, s ?
Thanks for any tips.
