i really love chemistry but unfortunate for me i dont have the best teacher.... any questions i ask she tells me to go do research on the net & in the library. & the thing is there is too much info sumtimes.....i just wanted to ask a few questions pls
is this reaction a Redox reaction or a Substitut reaction
Copper Sulphate (aq) + Water (aq) + Zinc (s) ---> Zinc Sulphate (aq) + Copper (s) + Hydrogen (g)
are these properly balanced because my teacher told me there is a special way to balance redox reaction but wont teach me
Cu (s) + 4HNO3 (aq) ----> Cu(NO3)2 (aq) + 2NO2 (g) + 2H2O (l)
Copper (s) + Nitric Acid (aq) ----> Copper Nitrate (aq) + Nitrogen Dioxide (g) + water (l)
Cu2SO4 + 4H2O (l) + Zn (s) ---> ZnSO4 (aq) + Cu (s) + 4H2 (g)
Copper Sulphate (aq) + Water (aq) + Zinc (s) ---> Zinc Sulphate (aq) + Copper (s) + Hydrogen (g)
