Question

Select all of the double replacement reactions.

A. CaO+CO, CaCO,
B. Na₂CO3 → Na₂O + CO₂
c. KCl + AgNO3 → AgCl + KNO3
D. Cu + Ag (NO3)₂ → Ag+ Cu(NO3)₂
E. H₂SO4 +2NaOH → Na₂SO4 + 2H₂O
C

Answer 1

Step-by-step explanation:

The double replacement reactions among the given options are:

C. KCl + AgNO3 → AgCl + KNO3

D. Cu + Ag(NO3)₂ → Ag + Cu(NO3)₂

These reactions involve an exchange of ions between two compounds, resulting in the formation of new compounds. In a double replacement reaction, the positive ions in the reactants switch places to form new compounds.

Therefore, options C and D are the double replacement reactions.
