Question

Out of the following equations I need
-one which yields a solid
-one which yields a gas
-one which produces heat
-one which produces a smell
-one no reaction
List:
H2SO4 + (NH4)2SO4
H2SO4 + Mg(NO3)2
H2SO4 + Na2CO3
H2SO4 + SrCl2
H2SO4 + NaOH
NaOH + (NH4)2SO4
NaOH + Mg(NO3)2
NaOH + Na2CO3
NaOH + SrCl2
Na2CO3 + (NH4)2SO4
Na2CO3 + Mg(NO3)2
Na2CO3 + SrCl2
(NH4)2SO4 + Mg(NO3)2
(NH4)2SO4 + SrCl2
Mg(NO3)2 + SrCl2

Thank you for your help!

Answer 1

you should write down the possible products for all the reactions to be able to see if there is any that can produce a gas or a solid or a smell or heat. Do you have any clue to narrow down the possibilities?
