  • Liquids can diffuse in liquids. Think of a drop of food colouring in water
  • It is the process of intermingling atoms from one substance into another.

The other answers are <em>incorrect</em> because:

40. Write a balanced equation and a net ionic equation for combining AgNO3(aq) and Na2CO3(aq)
Kay [80]

we are given the the two reactants: AgNO3 and Na2CO3 and is asked to write a balanced equation and a net ionic equation for the reaction of the two. This is a double-replacement reaction:
2AgNO3 (aq)+ Na2CO3 (aq)= Ag2CO3 + 2NaNo3 (aq)
2 Ag + + 2 N03- + 2Na+ + CO32- = Ag2CO3 + 2 Na+ 2NO3-
cancelling the spectator ions, 2Ag + + CO32- = Ag2CO3
