HELP ITS DUE SOON PLEASEE Identify the type of chemical reaction for each of the following:

SnO2(aq) + 2H2(g) → Sn(s) + 2H2O(g)

AgNO3(aq) + KI(aq) → AgI(s) + KNO3(aq)

2Fe(s) + 3Br2(l) → 2FeBr3(s)

3H2SO4(aq) + 2Fe(s) → Fe2(SO4)3(aq) + 3H2(g)

2C2H6(g) + 7O2(g) → 4CO2(g) + 6H2O(g)

4Al(s) + 3O2(g) → 2Al2O3(s)

2KI(l) → 2K(s) + I2(s)  

3CaCl2(aq) + 2Na3PO4(aq) → Ca3(PO4)2(s) + 6NaCl(aq)

The options are:
Single replacement
Double replacement
Decomposition
Formation
Hydrocarbon combustion

SnO2(aq) + 2H2(g) → Sn(s) + 2H2O(g) - Redox reaction

AgNO3(aq) + KI(aq) → AgI(s) + KNO3(aq) - double replacement reaction

2Fe(s) + 3Br2(l) → 2FeBr3(s) - Formation

3H2SO4(aq) + 2Fe(s) → Fe2(SO4)3(aq) + 3H2(g) - Single replacement

2C2H6(g) + 7O2(g) → 4CO2(g) + 6H2O(g) - Hydrocarbon combustion

4Al(s) + 3O2(g) → 2Al2O3(s) - Formation

2KI(l) → 2K(s) + I2(s) - Decomposition

3CaCl2(aq) + 2Na3PO4(aq) → Ca3(PO4)2(s) + 6NaCl(aq) - Double replacement

Explanation:

In an oxidation - reduction reaction, the oxidation number of the species involved in the reaction changes from left to right. One specie is oxidized while the other is reduced. E.g in SnO2(aq) + 2H2(g) → Sn(s) + 2H2O(g) - Sn^2+ was reduced while H2 was oxidized.

For a single replacement reaction, one specie is replaced in the reaction e.g H^+ is replaced by Fe^2+ in the reaction, 3H2SO4(aq) + 2Fe(s) → Fe2(SO4)3(aq) + 3H2(g) .

In a double replacement reaction, the ions on the reactant side exchange partners at the product side e.g 3CaCl2(aq) + 2Na3PO4(aq) → Ca3(PO4)2(s) + 6NaCl(aq)

In a formation reaction, two reactants combine to form a product. E.g 2Fe(s) + 3Br2(l) → 2FeBr3(s)

In a decomposition reaction, a compound breaks down to yield its components e.g 2KI(l) → 2K(s) + I2(s)

Hydrocarbon combustion refers to the reaction of a hydrocarbon compound with oxygen e.g 2C2H6(g) + 7O2(g) → 4CO2(g) + 6H2O(g)

its going to be mutualism cuz they both benefit from the relationship.
