Well let's start with an equation
PbO(s) + NH3(g) -->Pb(s) + N2(g) + H2O(g)
Balancing we get
3PbO(s) + 2NH3(g) --> 3Pb(s) + N2(g) + 3H2O(g)
Types of reactions include:
Combination or synthesis A + B ----> AB
Decomposition AB ----> A + B
Substitution or Single Replacement A + BC ----> B + AC
Metathesis or Double Displacement AB + CD ----> AD + CB
Does double displacement make sense...Can it be endothermic?
Not the answer you are looking for? Search for more explanations.
to me that reaction doesn't look like double replacement
In double displacement they switch places as I've shown above so I agree with @Photon336 with it not looking like a double displacement
yeah you explained it nicely, is it possible for a double replacement to be endothermic? I guess you can't really tell just by looking at the reaction, you would need the bond energies or enthalpy of reaction or something i guess.
You would have to look at the enthalpies of the products and the reactants in order to determine exoteric or endothermic
