Question

Which displacement reaction(s) will occur? Give reason.
a) CuSO4 + Mg → MgSO4 + Cu
b) H2SO4 (sulphuric acid) + Zn → ZnSO4+ H2(gas)

Answer 1

Answer:

Explanation:

b) 2Na + 2C2H5OH —→ 2C2H5ONa + H2; Displacement reaction ... (b) MgO + H2O —→ Mg(OH)2. 37. Zinc is above hydrogen whereas copper is below hydrogen in the ... Sulphur dioxide gas when passed through acidic dichromate ... H2SO4. HNO3. Salt obtained from. Formula. NH4Cl. CuSO4. NaCl. Mg (NO3)2. K2SO4.

Answer 2

Answer:

CuSO4 (aq) + Zn (s) → Cu (s) + ZnSO4 (aq) is an example of displacement reaction. Adisplacement reaction is a chemical reaction in which amore reactive element displaces a less reactive element from its compound.
