Question

From the below given Chemical Equation state its types. (i) CuO+H2---->heat Cu+H2O (ii) Pb(s)+CuCl2(aq) - - >PbCl(aq)+Cu(s) (iii) CH4(g)+2O2(g)- - ->CO2(g)+2H2O(g) (iv) C(s)+O2(g)- - ->CO2(g) (v) CaCO3(s)- - -> heat CaO(s)+CO2(g) (vi) Na2SO4+BaCl2(aq) - - -> BaSO4(s)+2NaCl(aq)​

Answer 1

Answer:

This is your answers

Explanation:

Double displacement reactions are those in which ions of the reactants are exchanged to form new compounds as products. 

Na+ion combines with Cl− ion and SO42− ion combines with Ba2+ ion to form two new compounds as sodium chloride (NaCl) and barium sulphate (BaSO4) respectively.
