Question

Conclusion on types of chemical reactions

Answer 1

Conclusion on kinds of chemical reactions:

• A chemical equation is an ingeniously compact manner of speaking quite a few records in a brief collection of parts.
• Modern chemical equations mirror our knowledge of being counted as being composed of atoms and of chemical reactions as a procedure of breaking bonds and rearranging atoms into new compounds.

Explanation:

• The motive of this test became to complete, look at, and stabilize every one of the exclusive kinds of chemical reactions which includes decomposition, mixture, single substitute, and double substitute.
• The motive became met due to the fact at some point in the test, we did look at at least one of every one of the reactions.
• Throughout the lab, we found  mixture reactions,  decomposition reactions,  single substitute reactions, one precipitate response, one gas evolution response, one acid-base response, and 3 times wherein there has been no response that took place.

Answer 2

Answer:

Their are total 5 types of chemical reactions.

Explanation:

1. Combination Reaction :

• A reaction in which two or more reactants combine together to form a single product is called as combination reaction.
• A + B → C
• E.g. C + O2 → CO2

2. Decomposition reaction

• When a single reactant breaks down into two or more product in the presence of a catalyst, then the reaction is known as decomposition reaction.
• A → B + C
• E.g. CaCO3 → CaO + CO2

3. Displacement Reaction :

• If in a reaction a more reactive element displaces a less reactive element and takes its place then the reaction is known as displacement reaction.
• AB + C → A + BC
• E.g. Cl2(aq) + 2NaBr(aq) → 2NaCl(aq) + Br2(aq)

4. Double Displacement Reaction

• If in a reaction when two ions formed in reactants part displaces each other and forms two different compounds, then the reaction is known as double displacement reaction.
• AB + CD → AC + BD
• E.g. Pb(NO3)2(aq) + 2 KI(aq) → 2 KNO3(aq) + PbI2(s)

5. Precipitation Reaction

• During the process of reaction, if a precipitate is formed at the bottom of the beaker then the reaction is known as precipitation reaction.
• A precipitate is a insoluble product formed during the reaction.
• E.g. NaCl(s) → Na+(aq) + Cl− (aq)
