Double Replacement Reactions Exchange of ions between two compounds Typically a precipitate is produced AX+BY -> AY+BX EX. The figure below clearly illustrates how this swap takes place. Understand that the atomic theory explains the conservation of matter: if the number of atoms stays the same no … EX: Cu + AgNO3 ---> Ag + Cu(NO3)2 Where Copper (CU) replaces Silver (Ag) to form copper nitrate (Cu(NO3)2) and silver by itself Double replacement is when you have two compounds which "trade partners" Ex: 2NaCl + H2SO4 ---> Na2SO4 + 2HCl Note that Sodium (Na) switches with Hydrogen (H) to form sodium sulfate (Na2SO4) and Hydrogen chloride (HCl) … The "double replacement reaction" is a very common type that takes place when two pairs of charged particles essentially "change partners." Check the sentence(s) that … Instructions: 1. So let's see here at first do we're first going to actually write a reaction of what exactly took place so we have K2CrO4 is reacting with silver nitrate, AgNO3, I'm sorry Ag yeah NO3 this is give me double replacement reaction may have two ionic compounds for producing silver chromate and potassium nitrate and we balance this we should have 2 here which means we should have 2 … "K2Cro4 Agno3" Essays and Research Papers . CaCO3 + HCl → CaCl2 + H2CO3 38. Pb(NO3)2 + K2CrO4 --> 3. HgO --> 6. This product is referred to as a precipitate, and the reaction is called a precipitation … The common names of the chemicals in the reaction are sodium hydroxide, silver nitrate, sodium nitrate, silver oxide and water.
