Identifying the Type of Chemical Reaction

Identify the type of Chemical reaction:

AB > A + B

• Decomposition

• Synthesis

• Single Replacement

• Double Replacement

Identify the type of Chemical reaction:

Pb(NO₃)₂ > Pb + 2 NO₂ + O₂

• Decomposition

• Synthesis

• Single Replacement

• Double Replacement

Answer explanation

Even though there are more than 2 products made, this is decomposition.

Why?

Because one compound is broken down into parts, those parts don't have to be individual elements.

Identify the type of Chemical reaction:

4 P + 3 O₂ > P₄O₆

• Decomposition

• Synthesis

• Single Replacement

• Double Replacement

Answer explanation

Two substances are combining to form a single complex structure. This is the very essence of synthesis reactions. Two combining into one.

Identify the type of Chemical reaction:

H + MO > HM + O

• Decomposition

• Synthesis

• Single Replacement

• Double Replacement

Identify the type of Chemical reaction:

2 KBr + Cl₂ > 2 KCl + Br₂

• Decomposition

• Synthesis

• Single Replacement

• Double Replacement

Answer explanation

This is a single replacement reaction because the Cl and the Br trade places in the compound.

A single element is replaced in a compound, and a single element displaced.
