Types Of Chemical Reactions | Quiz

Check changes in oxidation states.

1 / 5

Tags: Chemistry → Chemical Reactions, Oxidation-Reduction, Redox Concepts, Applying, 3 Marks

1 points

The reaction (CuO + H_2 rightarrow Cu + H_2O) is an example of:

” Combination Reaction

” Redox Reaction

” Decomposition Reaction

Think of oxidation and reduction together.

Well done! It involves both oxidation and reduction.

Step 1: \(CuO\) is reduced to \(Cu\).
Step 2: \(H_2\) is oxidised to \(H_2O\).
Step 3: Hence, it is a **Redox reaction**.

Observe the exchange of ions.

2 / 5

Tags: 3 Marks, Double Displacement, HOTS, Ion Exchange, Chemistry → Chemical Reactions

1 points

Identify the type of reaction: (AgNO_3 + NaCl rightarrow AgCl + NaNO_3)

” Displacement Reaction

” Combination Reaction

” Double Displacement Reaction

Look for ion exchange between compounds.

Excellent! Ions are exchanged.

Step 1: \(AgNO_3\) reacts with \(NaCl\) to form \(AgCl\) and \(NaNO_3\).
Step 2: Exchange of ions occurs.
Step 3: Hence, it’s a **Double Displacement reaction**.

Check if one element replaces another.

3 / 5

Tags: Chemistry → Chemical Reactions, Displacement, Metal Replacement, Understanding, 2 Marks

1 points

In the reaction (Zn + H_2SO_4 rightarrow ZnSO_4 + H_2), what type of reaction takes place?

” Double Displacement Reaction

” Displacement Reaction

” Combination Reaction

Observe if a metal replaces hydrogen.

Exactly! Zinc replaces hydrogen.

Step 1: Zinc displaces hydrogen from sulphuric acid.
Step 2: This is a **Displacement reaction**.

Check if a single compound breaks down.

4 / 5

Tags: Chemistry → Chemical Reactions, Decomposition, Reaction Breakdown, Applying, 2 Marks

1 points

What type of reaction is represented by (2KClO_3 rightarrow 2KCl + 3O_2)?

” Double Displacement Reaction

” Combination Reaction

” Decomposition Reaction

Notice the number of products formed.

Great! It’s a decomposition reaction.

Step 1: A single reactant \(KClO_3\) decomposes into \(KCl\) and \(O_2\).
Step 2: Hence, it is a **Decomposition reaction**.

Observe how two reactants combine.

5 / 5

Tags: Chemistry → Chemical Reactions, Combination Reaction, Reaction Identification, Understanding, 1 Mark

1 points

Identify the type of reaction: (2H_2 + O_2 rightarrow 2H_2O)

” Decomposition Reaction

” Displacement Reaction

” Combination Reaction

Look again at the product formed.

Correct! Two reactants combine to form a single product.

Step 1: Hydrogen and oxygen combine to form water.
Step 2: Two reactants combine to form one product.
Step 3: Hence, it is a **Combination reaction**.
