Question

classify the chemical reaction

Answer 1

which chemical reaction dude

Answer 2

Types of Chemical ReactionsSynthesis reactions 
Two or more reactants combine to make 1 new product.
Examples:
C(s) + O2(g) → CO2(g) 
H2O(l) + SO3(g) → H2SO4(aq) 

Decomposition reactions
A single reactant breaks down to form 2 or more products. 
Examples:
H2CO3(aq) → H2O(l) + CO2(g)
CaCO3(s) → CaO(s) + CO2(g)

Single-replacement reactions
A single element replaces a similar element of an adjacent reactant compound. 
Examples:
Zn(s) + CuSO4(aq) → ZnSO4(aq) + Cu(s) 

Double-replacement reactions 
Two ionic compounds exchange ions, producing 2 new ionic compounds. 
Examples:
NaCl(aq) AgNO3(aq) → NaNO3(aq) + AgCl(s)
HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l) 


Combustion reactions
A single element or compound combines with oxygen gas releasing energy. This rapid oxidation is called burning.
Examples:
C(s) + O2(g) → CO2(g) + energy
2Mg(s) + O2(g) → 2MgO(s) + energy

I hope it will help u....
