write 10 chemical equations for each type of chemical reactions.
Answers
During a chemical reaction, the substances that react are known as reactants whereas the substances that are formed during a chemical reaction are known as products. Six common types of chemical reactions are discussed below.
Combination reaction : Two or more compounds combine to form one compound.
A + B → AB
Decomposition reaction : The opposite of a combination reaction – a complex molecule breaks down to make simpler ones.
AB → A + B
Precipitation reaction : Two solutions of soluble salts are mixed resulting in an insoluble solid (precipitate) forming.
A + Soluble salt B → Precipitate + soluble salt C
Neutralization reaction : An acid and a base react with each other. Generally, the product of this reaction is a salt and water.
Acid + Base → Salt + Water
Combustion reaction : Oxygen combines with a compound to form carbon dioxide and water. These reactions are exothermic, meaning they give off heat.
A + O2 → H2O + CO2
Displacement reaction : One element takes place with another element in the compound.
A + BC → AC + B
Answer:
Combination Reactions
2Na(s)+Cl2(g)→2NaCl(s)
Decomposition Reactions
2HgO (s) → 2Hg(l) + O2 (g)
Displacement Reaction
Mg(s) + Cu(No3)2 (Aq) → Mg(No3)2 (Aq)+ Cu(s)
Double Displacement Reaction
NaCl2 + kSO4 → NaSO4 + KCl2
