Question

Please give 2 real-life applications of synthesis, decomposition, single and double displacement reactions.

Answer 1

Double Displacement Reaction Examples

The reaction between silver nitrate and sodium chloride is a double displacement reaction. The silver trades its nitrite ion for the sodium's chloride ion, causing the sodium to pick upHere are some examples of synthesis reactions:

   Water: 2 H2(g) + O2(g) → 2 H2O(g)

   Carbon dioxide: 2 CO(g) + O2(g) → 2CO2(g)

   Ammonia: 3 H2(g) + N2(g) → 2 NH3(g)

   Aluminum oxide: 4 Al(s) + 3 O2(g) → 2 Al2O3(s)

   Iron sulfide: 8 Fe + S8 → 8 FeS.

   Potassium chloride: 2 K(s) + Cl2(g) → 2 KCl(s) the nitrate anion

.Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen

A single-replacement reaction replaces one element for another in a compound. The periodic table or an activity series can help predict whether single-replacement reactions occur. A double-replacement reaction exchanges the cations (or the anions) of two ionic compounds.

Answer 2

Answer:

A synthesis reaction occurs when two or more reactants combine to form a single product. This type of reaction is represented by the general equation: A + B → AB. An example of a synthesis reaction is the combination of sodium (Na) and chlorine (Cl) to produce sodium chloride (NaCl).

Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.

Single displacement reactions are useful in understanding the patterns of reactivity of elements of the same type. One everyday item that we use that is the result of a single displacement is table salt. When calcium chloride reacts with sodium, the result is sodium chloride and calcium.

Double displacement reactions generally take place in aqueous solutions in which the ions precipitate and there is an exchange of ions. For example, on mixing a solution of barium chloride with sodium sulphate, a white precipitate of barium sulphate is immediately formed. These reactions are ionic in nature.
