Question

Match the appropriate name for each chemical reaction description provided.

1) A + B------------ -> AB
2) ABC --------------> AB + C
3)XY + Z ------------------> Y + XZ
4)CH4 + 2O2 -----------------> 2H2O + CO2
5)HNO3 (aq)+ LiOH (aq)-------------> H2O (l)+ LiNO3(aq)
6)2KI (aq) + Pb(NO3)2 (aq)------------> 2KNO3 (aq) + PbI2 (s)

Answer
A.
Decomposition
B.
Single-replacement
C.
Synthesis
D.
Neutralization double-replacement
E.
Combustion
F.
Precipitation double-replacemen

Answer 1

1. Combination, since two reactant molecules are combined together to form a new addition molecule.

2. Decomposition, since one molecule gets converted into two compounds

3. Single replacement Reaction. Since Y is replaced by Z

4. Combustion reaction, reaction of hydrocarbons with excess Oxygen.

5. Neutralization, reaction of acid and base gives salt and water.

6. Double displacement reaction

Answer 2

Reaction 1 is a synthesis type of reactant because it involves combination of two elements. Reaction 2 is a decomposition type since it breaks down the original compound to more than 1 compounds or elements. Reaction 3 is a single replacement reaction. Reaction 4 is a combustion type since it uses oxygen. Reaction 4 is a neutralization double-displacement since it exchanges the places of cations at the same time it produces water. Reaction 5 is a precipitation double-replacement since it also exchanges the places of cations at the same time produces a solid product.Answers are C, A, B, E, D, and F in order.
