Match the equation to its type

Question

1. AB + CD -> AD + CD
2. AB -> A + B
3. A + B -> AB
4. A + BC -> B + AC
5. HCl + Mg(OH)2 -> MgCI2 + 2H2O

A. Single - replacement reaction
B. Acid-base reaction
C. Synthesis reaction
D. Decomposition reaction
E. Double- replacement reaction

Answer 1

Here are the equations matched to their types:

1. AB + CD -> AD + CB - E. Double-replacement reaction
2. AB -> A + B - D. Decomposition reaction
3. A + B -> AB - C. Synthesis reaction
4. A + BC -> B + AC - A. Single-replacement reaction
5. HCl + Mg(OH)2 -> MgCl2 + 2H2O - B. Acid-base reaction

So the matches are: 1 - E
2 - D
3 - C
4 - A
5 - B
