Ca + 2HCl CaCl2 + H2Explanation / Answer
1. formation of CaCl2 from Ca and HCl is a exchange reaction. hydrogen is replaced calcium
2. formation of ammonium nitrate and barium chloride is an exchange reaction. nitrate group and chlorine group are exchanded.
3. formation of hudrogen and oxygen from H2O is a cleavage reaction. the braking of H2O will make the two companent Hydrogen and Oxygen.
4. calcium carbonate CaCO3 from calcium oxide CaO and CO2 is a condensation reaction. both the reactents are joined and formed the compound.
5. HCl and NaOH react to form NaCl and H2O is a exchange reaction. OH is repaced by chlorine atom. but in chemistry removal of water molecule after the reaction is called condonsation reaction. this reaction can also called neutralization reaction.
