Question

List whether the following equations are classified as single replacement, double replacement, combination, decomposition, combustion and/or oxidation reaction.

1) 2Mg(s) + O2(g) -> 2MgO(s)

2) Mg(s) + 2HCL (aq) -> MgCl2(aq) + H2

3) FeCl3 + 3NaOH -> Fe(OH)3 + 3NaCl

4) 3CuCl2 + 2Al -> 2AlCl3 + 3Cu

5) NaCl(aq) + AgNO3(aq) -> AgCl(s) + NaNO3

6) (NH4)2CO3 -> 2NH3 + CO2 + H20

Answer 1

Single displacement reaction (SD), is a chemical reaction in which one element replaces another elemente in _q_compound It can be represented af At B C AC #B_ This will most often occur it A i more reutine than B, thus giving a more stable product. Double displacement reaction (DP); Reaction in which two compounds in their aqueous solution react to form two product by intorchanging there radical orions i celled a double displacement reaction. It can be represented as - ABL CD - ADA CB.____ Decomposition reaction (1) - Chemical reaction in which two or more products are formed from a single reectant is called a decomposition reaction. It can be represented as -_-_-_-_ A * BIS ----

Combination reaction :- (It is also called synthese reaction) is a reaction where tho or more elements or compounds Creactants combine to form a single compound (Products, Such reaction may be represented as follow x+y - XY Combustion reection - is an exothermic reaction in which something reset with oxygen. 02 Mg (s) + O2(9) ► 2Mg0 (s) [ combinatim reection Combustion reaction) @ Mg(s) + znce (az) ~ Mylezlap) the [single displacement] © fech + 3Naon - Felony & 3 Nach [Double displacement . reection] 3u4, +2Al QA1} t cu [ Single displecement reaction] 8 Näcelifl + Agnozlop) → Agulla + Na nes ( Double displacement ! © (NH4), coz eN + Cos + Bo [Decompositum serction.
