I need help identifying the type of reactions. Can anyone help?
Eddi Din [679]

Answer:

Reaction 5: Decomposition reaction.

Reaction 6: Single replacement reaction

Reaction 7: Combination reaction.

Reaction 8: Combustion reaction.

Explanation:

<u><em>Reaction 5:</em></u>    2KClO₃ → 2KCl + 3O₂.

  • It is a decomposition reaction.
  • A decomposition reaction is a type of chemical reaction in which a single compound breaks down into two or more elements or new compounds.
  • In this reaction: potassium chlorate decomposes into two single components (potassium chloride and oxygen).
  • So, it is a decomposition reaction.

<u><em>Reaction 6:</em></u> Zn + 2HCl → H₂ + ZnCl₂.

  • It is a single replacement reaction.
  • A single-replacement reaction, a single-displacement reaction, is a reaction by which one (or more) element(s) replaces an/other element(s) in a compound.
  • It is most often occur if element is more reactive than the other, thus giving a more stable product.
  • In this reaction, zinc metal (more active) displaces the hydrogen to form hydrogen gas and zinc chloride, a salt. Zinc reacts quickly with the acid to form bubbles of hydrogen.

<u><em>Reaction 7:</em></u> N₂O₅ + H₂O → 2HNO₃.

  • It is a combination "synthesis" reaction.
  • A synthesis reaction has two or more reactants and only one product.
  • In this reaction, dinitrogen pentoxide reacts with water to produce nitric acid.
  • So, it is considered as a synthetic "combination" reaction.

<u><em>Reaction 8:</em></u> 2C₂H₆ + 7O₂ →  4CO₂ + 6H₂O.

  • It is a combustion reaction.
  • A combustion reaction is a reaction where hydrocarbon alkane is completely burned in oxygen to produce water and carbon dioxide.
  • In this reaction 1.0 mole of ethane is burned to give 4.0 moles of carbon dioxide and 6.0 moles of water.
  • So, it is considered as a combustion reaction.

9. What are the advantages of using an indicator to inform pH measurements? What are the advantages of using a pH meter?
Llana [10]

Answer:

The advantages of using an indicator to inform pH measurements:

It gives a mathematically result of the pH, in addition, it gives the precise pH of solvent, and it also gives an idea of the straight of the solution also.

Now, the advantage of using a pH meter:

It is a rapid method to characterize between acids, bases. However, this method does not show how strong acid or base actually are, plus it tends to gives a range of acidity or basicity not quite accurate as a result.
