## Question:

Identify the type of reaction for each of the following. Explain

AgNO3 + Na –> Ag + NaNO3
C6H12O6 –> 6C + 6H2O
KOH + HBr –> KBr + H2O
4Al + 3O2 –> 2Al2O3
2C6H6 + 15O2 –> 12CO2 + 6H2O

AgNO3 + Na → Ag + NaNO3    = Single replacement reaction

C6H12O6 → 6C + 6H2O           =  Decomposition reaction

KOH + HBr → KBr + H2O          =  Acid-base reaction

4Al + 3O2 → 2Al2O3                =  Synthesis reaction

2C6H6 + 15O2 → 12CO2 + 6H2O   =

Combustion Reaction

Explanation:

Single replacement reaction

AgNO3 + Na → Ag + NaNO3

A single replacement reaction is a chemical reaction in which one element is substituted for another element in a compound. In single replacement reaction, metal is usually replaced with another metal while non metal is replaced with another non metal. The element that displace the other element is usually more reactive. In this scenario sodium is more reactive and electropositive  than silver , so it will easily displace silver in the compound.

Decomposition reaction

C6H12O6 → 6C + 6H2O

A decomposition reaction is a chemical reaction which a single reactant yields two or more products. it is a chemical reaction in which a single compound split to form two or more compound or elements. From the reaction above the glucose compound disintegrate to form carbon and water molecule.

Acid-base reaction

KOH + HBr → KBr + H2O

The reaction above is a Acid-base reaction. The reaction is also known as a neutralization reaction. The acid react with the base to form salt and water.

The base in this scenario is potassium hydroxide and the acid is hydrogen bromide . Both compound react to form potassium bromide(salt) and water.

Synthesis reaction

4Al + 3O2 → 2Al2O3

A synthesis reaction is a chemical reaction where two or more reactants combine together to form a single product.  The reaction above combines aluminium and oxygen to form a single product known as aluminium oxide.

Combustion Reaction

2C6H6 + 15O2 → 12CO2 + 6H2O

A combustion reaction involves the burning of a substance. The substance usually react rapidly with oxygen. The products of combustion are usually carbon dioxide and water vapor.  The reaction usually give heat and light.
