Interpretation Introduction

Interpretation:

To classify each of the following as a combination, decomposition, single replacement, double replacement or combustion reaction.

${\text{H}}_{\text{2}}{\text{(g) + Br}}_{\text{2}}\text{(g) }\to \text{2HBr(g)}$

${\text{Ag}}_{\text{2}}{\text{NO}}_{\text{3}}\text{(aq) + NaCl(aq)}\to {\text{AgCl(s) + NaNO}}_{\text{3}}\text{(aq)}$

${\text{2H}}_{\text{2}}{\text{O}}_{\text{2}}\text{(aq) }\to {\text{2H}}_{\text{2}}{\text{O(l) + O}}_{\text{2}}\text{(g)}$

${\text{Zn(s) + CuCl}}_{\text{2}}\text{(aq) }\to {\text{ Cu(s) + ZnCl}}_{\text{2}}\text{(aq)}$

${\text{C}}_{\text{5}}{\text{H}}_{\text{8}}{\text{(g) + 7O}}_{\text{2}}\text{(g) }\stackrel{\text{Δ}}{\to }{\text{5CO}}_{\text{2}}{\text{(g) + 4H}}_{\text{2}}\text{O(g)}$

Concept introduction:

Reaction type	Explanation	General formula
Combination reaction	Two or more compounds combine to form one compound	$\text{A+B }\to \text{AB}$
Decomposition reaction	A single compound decomposes into two or more simple substances.	$\text{AB}\to \text{A+B}$
Precipitation reaction	Reaction that result in the formation of an insoluble product.	$\text{A+ Soluble salt B }\text{}\to \text{Precipitate+ Soluble salt C}$
Neutralization reaction	Acid and base react together to form a salt and water.	$\text{Acid + Salt}\to \text{Salt + Water}$
Combustion reaction	Compound reacts with oxygen to form carbon dioxide and water.	${\text{A + O}}_{\text{2}}\to {\text{H}}_{\text{2}}{\text{O + CO}}_{\text{2}}$
Single replacement reaction	In a compound one element replaces another element.	$\text{A + BX}\to \text{AX + B}$
Double replacement reaction	It occurs when different elements of different compounds replace different atoms.	$\text{AY + BX }\to \text{AX + BY}$
