double replacement reaction

A ________________ is a chemical change involving an exchange of positive ions between two compounds.

Dalton said that the atoms of reactants are rearranged to form new substances as products

How did John Dalton explain a chemical reaction using his atomic theory?

CS2 + 3Cl2 ---> CCl4 + S2Cl2

Balance this equation: CS2 + Cl2 ---> CCl4 + S2Cl2

3Zn(OH)2 + 2H3PO4 ---> Zn3(PO4)2 + 6H2O

Balance this equation: Zn(OH)2 + H3PO4 ---> Zn3(PO4)2 +H2O

2AgNO3 + H2S ---> Ag2S + 2HNO3

Balance this equation: AgNO3 + H2S ---> Ag2S + HNO3

FeCl3 + 3NaOH ---> Fe(OH)3 + 3NaCl

Balance this equation: FeCl3 + NaOH ---> Fe(OH)3 + NaCl
