The correct answer is Option [3] i.eastward. Combustion reaction.
Key Points
- Types of Chemical Reactions-The The basis for unlike types of reactions is the production formed, the changes that occur, the reactants involved, and so on. Different types of reactions are
- Combustion reaction
- Decomposition reaction
- Neutralization reaction
- Precipitation or Double-Displacement Reaction
- Combustion Reaction-
- It is a reaction with acombustible material with anoxidizer to requite an oxidized product.
- An oxidizer is achemical a fuelrequires to burn, generally oxygen.
- An case of the combustion of magnesium metal.
2Mg + O2→2MgO + Heat
Here,two magnesium atoms react with a molecule of oxygen-producing 2 molecules of the compound magnesium oxide-releasing some heat in the process.
- Decomposition Reaction-
- It is a reaction in which a single component breaks downward intomultiple products.
- Certainchanges in free energy in the environment have to be fabricated likeheat, light, or electricity breaking bonds of the chemical compound. for case of the decomposition of calcium carbonate gives out CaO (Quick Lime) which is a major component of cement.
CaCOthree(due south)→CaO(s)+COii(grand)
Hither, the chemical compound Calcium carbonate when heated breaks downward into Calcium Oxide and Carbon Dioxide.
- Neutralization Reaction-
- Information technology is basically thereaction between an acid and a base of operations giving common salt and water equally the products.
- The water molecule formed is by thecombination of OH- ions and H+ ions. Theoverall pHof the products when a strong acid and a stiff base undergo a neutralization reaction will be 7.
- Consider theexample of the neutralization reaction between Muriatic acid and Sodium Hydroxide giving out sodium chloride(Common Common salt) and h2o.
HCl + NaOH → NaCl + H2O
Here, an acid and a base of operations, Hydrochloric acid, and Sodium Hydroxide react in a neutralization reaction to produce Sodium Chloride(Common Table salt) and Water every bit the by-products.
