This reaction is highly exothermic:Fe2O3 + 2 Al = 2 Fe + Al2O3
Two types of displacement reactions are known:- single displacement- double displacement
how chemical energy produce in firewood useful
Exothermic reactions give off heat.
Activity series are useful for single displacement reactions.
Yes, the combustion of coal (oxydation reaction) is an exothermic reaction, releasing heat.

can anyone help me
An activity series of metals can predict whether a replacement (displacement) reaction will occur. You use the activity series to compare the reactivity of different metals in order to predict whether a replacement reaction will occur. A metal that is above another metal in the series will replace that metal in a compound.
Yes,burning fuel is a useful chemical reaction as energy is released and can be converted into different forms to do useful work
Exothermic and Endothermic reactions are part of the natural universe. Without it, temperatures would remain stagnate. In light of technology harnessing these reactions, they provide us with a number of useful abilities. They are useful in that we use these reactions to cook our food, heat our water, cool our airs and refrigerate our storages, to name a few.
Exothermic reactions give off heat.
its not.
Activity series are useful for single displacement reactions.
