Combination reaction

Also known as a synthesis reaction. One kind of frequently occurring combination reaction is the reaction of an element with oxygen to form an oxide. Under certain conditions, metals and nonmetals both react readily with oxygen. Once ignited, magnesium reacts rapidly and dramatically, reacting with oxygen from the air to create a fine magnesium oxide powder.

C2H2 + CH3OH => CH3OCHCH2 Na2O + SO2 => Na2SO3 NaOH + CO2 => NaHCO3 H2 + I2 => 2HI 3Mg + 2P => Mg3P2 C + CO2 => 2CO Cl2 + Be => BeCl2 View All Combination reaction

Decomposition reaction

Many decomposition reactions involve heat , light, or electricity to input energy. Binary compounds are compounds which consist of only two elements. The simplest sort of reaction to decomposition is when a binary compound breaks down into its elements. Mercury (II) oxide, a red solid, decomposes to form mercury and oxygen gas when heated. Also, a reaction is regarded as a decomposition reaction even if one or more of the products are still a compound. A metal carbonate breaks down to form a metal oxide and carbon dioxide gas. Calcium carbonate for example decomposes into calcium oxide and carbon dioxide.

3HClO3 => H2O + 2ClO2 + HClO4 HNO3 + HBr => Br2 + H2O + NO2 2NaHCO3 => H2O + Na2CO3 + CO2 Cu(OH)2 => CuO + H2O (NH4)2SO4 => H2SO4 + 2NH3 C2H5Cl => C2H4 + HCl CaCl2 => Ca + Cl2 View All Decomposition reaction

Oxidation-reduction reaction

An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron. Redox reactions are common and vital to some of the basic functions of life, including photosynthesis, respiration, combustion, and corrosion or rusting.

4HCl + O2 + 2CH2=CH2 => 2H2O + 2ClCH2CH2Cl Cl2 + Cu => CuCl2 H2O + 2KMnO4 + 3K2SO3 => 2KOH + 2MnO2 + 3K2SO4 4H2SO4 + 4FeSO4 + K2MnO4 => 2Fe2(SO4)3 + 4H2O + MnSO4 + K2SO4 O2 + 4Fe3O4 => 6Fe2O3 H2O + NaH => H2 + NaOH 3H2SO4 + 2KMnO4 + C6H5CHCH2 => 4H2O + 2MnSO4 + K2SO4 + CO2 + C6H5COOH View All Oxidation-reduction reaction

Single-replacement reaction

A + BC → AC + B Element A is a metal in this general reaction and replaces element B, a metal in the compound as well. If the replacement element is a non-metal, it must replace another non-metal in a compound, and it becomes the general equation. Many metals easily react with acids, and one of the reaction products when they do so is hydrogen gas. Zinc reacts to the aqueous zinc chloride and hydrogen with hydrochloride acid (see figure below).

2HCl + Mg => H2 + MgCl2 Fe + 2HCl => FeCl2 + H2 Fe + CuSO4 => Cu + FeSO4 2AgNO3 + Cu => 2Ag + Cu(NO3)2 2HNO3 + Ni => H2 + Ni(NO3)2 H2SO4 + Mg => H2 + MgSO4 CH3CH2CH2OH + C2H5COOH => H2O + C2H5COOCH2CH2CH3 View All Single-replacement reaction

Double-replacement reaction

AB + CD → AD + CB A and C are positive charged cations in this reaction, while B and D are negative charged anions. Double-replacement reactions typically occur in aqueous solution between the compounds. To cause a reaction, one of the products is usually a solid precipitate, a gas, or a molecular compound like water. A precipitate forms in a double-replacement reaction when the cations from one reactant combine to form an insoluble ionic compound with the anions from the other reactant. The following reaction occurs when aqueous solutions of potassium iodide and lead ( II) nitrate are blended.

H2S + LiOH => H2O + LiSH AlCl3 + 3NaOH => Al(OH)3 + 3NaCl AgNO3 + NaI => NaNO3 + AgI Ba(NO3)2 + H2SO4 => 2HNO3 + BaSO4 H2S + CuSO4 => CuS + H2SO4 3Ca(NO3)2 + 2Na3PO4 => Ca3(PO4)2 + 6NaNO3 2NaOH + ZnO => H2O + Na2ZnO2 View All Double-replacement reaction
