What does this reaction suggest? MgSO4 + Cu →CuSO4 + Mg
This reaction occurs only at high temperatures.
This reaction can not occur.
This reaction is a decomposition reaction.
Copper is more reactive than magnesium.
Metal that are less reactive, cannot displace more reactive metal from their salt solution. Hence the reaction will not occur.
Is decomposition of vegetable is exothermic or endothermic reaction? If it is exothermic reaction than what type of decomposition reaction is this?
Fe2O3 + 2Al → Al2O3 + 2Fe
This reaction is an example of :
