Answer 1

Answer:

mg+02----> mg0

zn + cuso4-----> znso4 +cu

3) reaction cannot take place

Answer 2

Answer:

Magnesium + Oxygen → Magnesium oxide

2Mg+O

2

→2Mg

Zn+CuSO4=Cu+ZnSO4 Balanced Equation|| Zinc+Copper sulphate=Copper+Zinc sulphate Balance

The overall reaction is: Mg(s) + CuSO4(aq) --> MgSO4(aq) + Cu(s); the magnesium, because it is more reactive than copper, displaces it. The blue solution will turn reddish black with the introduction of Mg.
