They both come up with two different compounds/elements then the original compound/element.
decomposition
I believe there are 6... (I'm a chemistry major) Combustion, synthesis, decomposition, single displacement, double displacement, and acid-base.
Neutralization, Double decomposition, Alkylation, Counterion Exchange, Precipitation are all different types of double displacement reactions.
Types of chemical reactions:- synthesis- decomposition- single displacement- double displacement
Read details at this useful link.
Examples of chemical reactions: neutralization, thermal decomposition, synthesis, single displacement, double displacement.
It is synthesis because new things are being produced
Thermal decomposition. MgCO3(s) ==heat==> MgO + CO2
Single displacement reaction and a double displacement reaction are redox reactions. apex- false
If you mean Zn + H2SO4 --> ZnSO4 + H2, then no, it is not a decomposition reaction. In decomposition reactions one reactant is broken down into two or more simpler substances. For example, the electrolysis of water, 2H2O --> 2H2 + O2 is a decomposition reaction. The reaction referred to in your question is a double replacement (displacement) reaction. I apologize that the subscripts are not working at this time.
A single displacement reaction is always a redox reaction, buta double displacement reaction is not a redox reaction.
